8 Recommended Installation Procedure Please read and observe the instructions and guidelines in Section 3 Safety and Precautions (page 22) prior to installation. Failure to follow these instructions and guidelines may cause personal injury and/or damage to the equipment. 1. If fitted, then remove the V400 front panel by undoing the two captive M3 Pozidriv screws on the right side of the front panel. 2. Fit the mainframe into a 19-inch standard equipment rack on supporting rails, and secure the mainframe in position using the fixing screws and washers provided; see Figure 2. 1) This equipment is heavy (max. 20 kg). Please lift and handle with care to avoid strain or impact injuries, and follow the recommended installation procedure. Install modules after mounting mainframe in equipment rack. 2) Do not use the handles to lift or carry the mainframe. The handles are designed for sliding the unit into and out of the equipment rack, and not to support its weight. Use the underside edges of the mainframe to lift and carry it. 3) Always ensure adequate ventilation is provided for the equipment by fitting 1U ventilation panels above and below the equipment, and do not obstruct ventilation holes.

9 3. If a M400 Amplifier Module is being inserted, and connected to an ASL AEL (Active End of Line Device), the link setting on the M400 Amplifier Module needs to be adjusted as shown; see Figure 3. Figure 3 Setting the link on a M400 M400 DO NOT MAKE ANY OTHER CHANGES EOL10K/NO LINE MONITORING THIS IS THE DEFAULT POSITION JUMPER SEATED ON THE TWO FRONT PINS. THE FRONT PINS ARE POSITIONED FURTHEST FROM THE TRANSFORMER AT THE REAR OF THE MODULE. AEL LINK ENABLED: JUMPER SEATED ON THE TWO REAR PINS. THE REAR PINS ARE POSITIONED CLOSEST TO THE TRANSFORMER AT THE REAR OF THE MODULE. 4. Insert the chosen amplifier modules through the front of the mainframe, using the guides on the inside top of the mainframe to locate them correctly; see Figure 4. 1) Ensure that the amplifier module s side panels are located in the mainframe slides on the inside top of the mainframe. 2) Ensure that the amplifier module is pushed fully home so that its rear connector(s) mates the matching connector(s) in the mainframe. 3) Do not change any hardware settings on the amplifier module. These are set in manufacture for optimum performance. Page 9 of 24

FIT THE M3 TRANSIT POZIDRIV SCREWS TO THE LEFT HAND SIDE OF ALL AMPLIFIER MODULES AS SHOWN ABOVE. 1) The transit screws may be removed when the amplifiers are in situ to facilitate easy removal of the modules. 2) To remove Amplifier modules, release the transit screws and grip the cross-rod at the front of the module to slide it from the mainframe. The screws attaching the two parts of a M400 amplifier module together should never be removed. 6. Ensure that the power to the mainframe is disconnected. 1) Ensure that the mainframe mains and battery switches are turned off; see Figure 6. 2) Ensure that the AC mains supply to the unit is isolated. 3) Ensure that the DC supply to the unit is isolated, if used 7. Set the mainframe address as specified in the system design documentation; see Figure 6.

12 8. Set the rear-panel EARTH LIFT switch to the DOWN (, ON) grounded position; see Figure 7. Set the EARTH LIFT switch to the UP (, OFF) position to remove the mains earth from the signal circuit if a +ve ground battery system is used, or it is necessary to avoid a ground loop problem. It is possible to form a ground loop when connecting pieces of audio equipment using unbalanced connections that provide alternative earth connections via their cable screens. Such ground loops result in audible hum from the system. Never disconnect the mains earth from the plug to attempt to cure a ground loop. In the event of a fault, the equipment casing could become live. The recommended method of wiring low-level signal interconnections to preserve EMC (Electromagnetic Compatibility) performance and minimise the likelihood of ground loops is as follows: 1) We always recommend screen to shell connection for best EMC performance, but break the connection at the source end if a ground loop problem is encountered. In practice, the connections between this equipment are balanced and short and it is unlikely that ground loop problems will be encountered. 2) It is also possible to switch the rear panel EARTH LIFT switch to the UP (, OFF) ungrounded position. In some cases this may cure the problem. Figure 7 Setting the Earth Lift switch EARTH LIFT DOWN 9. Set the DIP switches at the rear of the mainframe as required; see Figure 8. The internal DIP switches must be set before the last interface card (the one closest to the AC mains socket) is fitted. Page 12 of 24

AC mains faults ARE reported. (1) Battery supply faults ARE reported. (1) Aux supply faults ARE reported. (1) Mainframe CPU faults are reported by front panel LED latching ON. Set to ON only if the mainframe is being used 'stand-alone', and it is desired that CPU reset causes LED to latch on. Amplifier mainframe is automatically switched off if the standby battery voltage drops below 21 V. This protects the battery from being completely discharged. AC Mains faults ARE NOT reported. Use only when the mainframe is being supplied from batteries only. Battery supply faults ARE NOT reported. Use only when the mainframe is being supplied from AC mains only (no batteries). Aux supply output faults ARE NOT reported. Use only when the auxiliary DC supply output is not being used to power other equipment. Mainframe CPU faults not latched by the front panel LED. Set to OFF for all Voice Alarm applications where the mainframes are integrated with a VAR Router.

The temperature and humidity ranges shown in the specifications for this product must not be exceeded. This equipment must not be installed in an area that is subject to a corrosive atmosphere, excessive moisture or may allow water or other liquids to come into contact with the unit or its external connections. You must switch off AC mains and battery supplies before plugging/unplugging amplifiers or you may damage the mainframe, and amplifier card electronics. External 24 V DC batteries connected to this unit can deliver very high currents that could cause fire or burns. Take care to avoid short circuits of the battery supply by tools or jewellery. Electrical Safety This product contains wiring that is energised to 230 V RMS AC mains and 100 V RMS audio signals at up to 20 khz. ESD Precautions This product contains static-sensitive devices. Observe ESD precautions when handling this product. Terminals marked with the symbol are hazardous, and the external wiring connected to these terminals requires installation by qualified personnel only. Always ensure that the equipment is correctly earthed by connection to an AC mains supply with a protective earthing connection. Ensure power supply cabling is adequately rated for the unit s operating current and protected, in case of short circuit, by a correctly rated fuse or circuit breaker. This is particularly important for supply feeds from the 24 V backup batteries which can deliver short circuit currents of several hundred amps. Weight Safety This equipment is heavy (max. 20 kg). Please lift and handle with care to avoid strain or impact injuries, and follow the recommended installation procedure. Install modules after mounting mainframe in equipment rack. Do not use the handles to lift or carry the mainframe. The handles are designed for sliding the unit into and out of the equipment rack, and not to support its weight. Use the underside edges of the mainframe to lift and carry it. Always replace blown fuses with the correct type and rating. Note that this equipment is intended for continuous operation and the front panel mains switch is not readily accessible without the use of tools to remove the front cover. Note that if the amplifiers are connected as a system which is permanently connected to the mains, then an all-pole mains isolator with a separation of 3 mm in each pole shall be incorporated in the electrical installation. Cabling Cables for the AC mains and DC battery supplies must be adequately rated for the expected currents that it will be carrying. Using too thin a cable can cause a safety hazard and will give excessive voltage drop and operational failure. EMC In the close proximity of some radio frequency transmitters, the signal to noise ratio of this product may be reduced. If this occurs, re-location of the equipment or the signal cables is recommended. Page 22 of 24

23 Ground Loops It is possible to form a ground loop (earth loop or hum loop) when connecting pieces of audio equipment using unbalanced connections that provide alternative earth connections via their cable screens. Such ground loops result in audible hum from the system. Packing for Return for Repair All electronics assemblies must be properly packed in ESD protective packing for transport, to prevent physical and ESD damage. Never disconnect the mains earth from the plug to attempt to cure a ground loop. In the event of a fault, the equipment casing could become live. Unpacking and Handling The equipment should be unpacked and inspected immediately on receipt. If damage has occurred please advise your carrier or supplier. The filler material used for packing for return for repair must be antistatic or static dissipative, as this may come into contact with exposed connectors, wiring, or PCB assemblies. The use of nonconductive filler material may cause damage to the electronic assemblies reducing their operational life, or even destroying them. This equipment contains electronic devices that are sensitive to electrostatic discharge. Please take precautions to avoid damage to the electronics by static electricity.
