1 36 to 120 k for small installation protection Data Sheet 2789_en_F 1 Description PHOEIX OTT Features The (SPD) provides surge protection in a compact, affordable package. high-energy suppression circuit provides 36 to 120 k (depending upon the model) of surge current rating per phase. Each surge suppression mode in the is individually fused for safety. The SPD uses a sealed, EM 4X housing, allowing installation in harsh environments with limited space. Operating status lights are easily observed and provide verification of protection. The VL-SQ SI provides compact protection of 120 V applications with bonded neutral and ground. The VL-SQ SI is for three-phase Wye applications up to 600 V with bonded neutral and ground. The VL-SQ SI D is for three-phase Delta applications up to 600 V. The 120/240S SPDs are for single- and split-phase 120/240 applications with common or separate neutral and ground. ompact design for flexible mounting locations 36 to 120 k surge current capacity per phase (L- and -G) protects against high-energy lightning strikes and transient voltages UL nominal surge discharge current (I n ) rating of 10 k EM 4X enclosure LEDs provide continuous feedback on the status of each phase UL/cUL listed; meets UL rd edition DGER: HZRD OF ELETRI SHOK OR R FLSH onfirm the SPD voltage rating on the module or nameplate label is the same as the operating voltage. Risk of electric shock. Disconnect power before installing or servicing. Service to be performed by qualified personnel only.

7 Type 1 SPDs can be connected on either side of the service entrance. Disconnects to the SPD are recommended. ll wires must be connected to properly installed circuit breakers sized according to the wire gauge. Use an appropriate breaker, i.e., 2- or 3-pole, for the electrical configuration. 7 Operation LEDs indicate the operating status of the individual phases of the The LEDs illuminate when the relevant phase is operating correctly. Device LED Phase LEDs Phase LEDs ll wires must be connected for the SPD to function correctly. The wires between the SPD and protected device should be twisted 1/2 turn every 12 in. (300 mm). Do not loop or coil wire. Excess wire must be removed without applying stress to wires. Figure 11 LED location If a phase is not operating correctly or a fault occurs, the corresponding LED is not lit. When a phase LED is not lit, verify the correct voltage is present on each phase. If power is present, the VL-SQ SI must be replaced. There are no serviceable parts. 2789_en_F PHOEIX OTT GmbH & o. KG lomberg Germany Phone: +49-(0) PHOEIX OTT P.O.ox 4100 Harrisburg P US Phone:
