Instruction Manual

INSTALLATION
Pre-Plan your installation. You need to accomplish the following:
▪ Meet all National and Local codes (NEC
®
Article 285 and UL 1449 address SPDs).
▪ Conrm System voltage to SPD voltage (120V SPD will fail instantly on 240V, 277V, etc.).
▪ Mount SPD as close to panel or equipment as possible to keep leads short. (long leads hurt performance).
▪ Ensure leads are as short and straight as possible, including neutral and ground. If using a
breaker, use a breaker position that is close to the SPD and the panel’s neutral and ground.
▪ If using a breaker, recommended breaker size is 30A due to 10 AWG conductor.
▪ Make sure system is grounded per NEC
®
and clear of faults before energizing SPD.
(inadvertent system problem may fail SPD).
▪ Never Hi-Pot test Any SPD. (will prematurely fail SPD).
▪ Do not install the XCS through the bottom of a NEMA 3R panel. Dripping water will
prematurely fail the SPD.
1. Use voltmeter to check voltages and ensure correct SPD. See Data Sheet for specs and wire-outs.
2. Determine Mounting location – weather resistant equipment may be required.
3. If SPD has optional Dry Contact Flush Mount Kit, or Remote Indicator, pre-plan their installation. See
Figure 3. (If ush mounting, be careful to not drop SPD into wall).
4. Remove power from panel/source. Conrm panel/source is deenergized.
5. Identify breaker location and SPD location. Position SPD such that LEDs are best visible.
6. Mount SPD – weather resistant applications require additional sealing, etc. (not included)
- Remove an appropriately sized knockout from panel.
- Connect conductors as appropriate – short and straight as possible (Hi-Legs are Phase B).
- Note that the metallic connection hub is not grounded within the SPD and proper grounding
requires connection of the green conductor ground.
7. Label or mark conductors as appropriate (neutral: white, ground: green, energized: black, hi-leg: orange).
8. Make sure system is bonded per NEC
®
and is clear of hazards or faults before energizing
(N-G bonding not per NEC
®
will fail SPDs: #1 cause of SPD failures).
9. Energize and conrm proper operation of green LED indicators and/or options.

(Type 1 or individual equipment installations may vary)
▪ Use closest breaker
to SPD
▪ Locate SPD close to
intended breaker
▪ Keep Leads Short
as Possible
▪ Avoid Sharp Bends
▪ Rotate XCS such
that LED indicator is
most visible
▪ Outdoor installation requires appropriate weather
sealing at nipple (gasket, sealing conduit, etc.)

VERIFY THAT ALL POWER CIRCUITS ARE
DEENERGIZED BEFORE MAKING CONNECTIONS
All electrical connections should be performed by a qualied (licensed)
electrician or technician. All wiring must comply with the National
Electrical Code (NEC
®
) and applicable local codes.
