XT-40 & IT-RSS Installation IM01005012E 2 INSTALLATION 2.1 Before Installation Perform or plan the following before installing the SPD: 1. Locate your electrical system’s applicable wiring diagram in Sections 2.2 & 2.3 2. Verify that your electrical system’s voltage and wiring configuration matches that of the SPD as shown on its label. 3. De-energize the SPD, and follow safe work practices to avoid an electrical shock hazard. 4. Ensure that a Neutral to Ground/Earth bond is present at

See Figure 2-1. When applicable, use weatherproof (corrosion resistant) conduit and fittings to maintain the enclosure’s NEMA 4 or 4X rating. If the system utilizes an isolated ground, then the SPD’s housing must be isolated from ground using insulated conduit fittings. Figure 2-1. Conduit Installation

IM01005012E XT-40 & IT-RSS Installation 2.8 Power Up and System Checkout Apply system power and observe that the LED(s) on the front of the SPD should glow. One LED should glow for each Phase voltage being monitored. Should there be a significant difference in brightness, check the phase rotation of the panel and ensure that the SPD’s Phase wires are connected to the correct phase. Slight differences in brightness DO NOT indicate a faulty device, rather specification tolerance differences
