Apply appropriate personal protective equipment (PPE) and follow electrical work practices. 1 Only qualified electrical personnel may install and service this equipment. 3 Never open SPD. No serviceable parts are inside. WARNING: This equipment depends upon an effective ground. Failure to obtain a quality ground connection may result in explosion or arc flash. NOTE: Megger® or hi-potential tests will damage this surge protective device. Turn off all power supplying the equipment and isolate the surge protective device before testing. 1 2 Figure 2 4. 6.1 1. Mounting and connection Position the VAL-SQ SI… so the LEDs are visible and the wires are as short and straight as possible. The SPD can be mounted in any orientation. It attaches through any side of the enclosure being protected using 1/2-NPT threaded nipple. SPD Protected device 3 Strain relief nut Mounting the SPD Connect the VAL-SQ SI… to the appropriate phases and ground lines as shown on the following illustrations. Wires are color coded as shown. If equipped with a green wire, it must be connected to ground. VAL-SQ SI Series NOTE: Surge Protective Device TRABTECH Cover or remove components inside any enclosure before drilling to prevent shavings from causing short-circuits across terminals and races. 2. 3. www.phoenixcontact.com 1 2 121 Create a hole in the enclosure, 2, for 1/2-in. conduit attachment, approximately 7/8 in. (22 mm) diameter. Route the wires and nipple through the hole and secure the VAL-SQ SI… to the enclosure with the strain relief nut, 3.

The SPD must be connected to power through a circuit breaker rated appropriately for the connected wire gauge. Use an appropriate breaker, i.e., 2- or 3-pole, for the electrical configuration. VAL-SQ SI Series 1 2 Surge Protective Device TRABTECH www.phoenixcontact.com Black White All wires must be connected for the SPD to function correctly. 2 1 11 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.
