Choose a smooth surface for an installation location (a wall, panel and etc.).. Open the white cover by releasing the locking plates on both sides of the cover and remove it. (See Fig. Locking plates release.). Insert the cables through the cable opening of the enclosure rear lid. (See Fig. Mounting dimensions.). Fix the unit to the wall / panel taking into account that the unit has to be installed at a minimum height of, m and the air flow has to pass free. Mind the correct mounting position and unit dimensions. See Fig. and Fig..

ATTENTION Do not exceed the maximum power supply rating! Measure before installation! Unregulated VAC supply units provide higher nominal output voltage and activate the integrated fuse protection.

7 ATTENTION Do not exceed the maximum power supply rating! Measure before installation! Unregulated VAC supply units provide higher nominal output voltage and activate the integrated fuse protection. ATTENTION If a G-type article is using the same AC power supply source (transformer) as F-type article, a SHORT CIRCUIT may result when the power supply and analogue signal terminals are connected to the same common ground! In this case always connect different article types to separate AC transformers or use the same article version. VERIFICATION OF INSTALLATION INSTRUCTIONS Check the status of the blue ON/OFF LED after you switch on the power supply. (See Fig. 8.) The ON/OFF LED should blink during the initialization period (0 s) at equal intervals. Then it should give out continuous blue light. If this is not the case, check the connections again. Fig. 8 Operating indication TRANSPORT AND STOCK KEEPING INFORMATION Avoid shocks and extreme conditions; stock in original packing. WARRANTY INFORMATION AND RESTRICTIONS MAINTENANCE Two years from the delivery date against defects in manufacturing. Any modifications or alterations to the product after the date of publication relieve the manufacturer of any responsibilities. The manufacturer bears no responsibility for any misprints or mistakes in this data. In normal conditions this product is maintenance-free. If soiled, clean with a dry or dampish cloth. In case of heavy pollution, clean with a non aggressive product. In these circumstances the unit should be disconnected from the supply. Pay attention that no fluids enter the unit. Only reconnect it to the supply when it is completely dry. 7-7
