INSTALLATION
:
Plan your installation and accomplish the following:
• Meet all National and Local codes (NEC
®
Article 285
and UL 1449 address SPDs).
•
Confirm System voltage to SPD voltage (120V SPD will
fail instantly on 240V, 277V, etc.).
• Mount STXP as close to panel or equipment as possible,
keeping leads as short as possible.
• Ensure leads are as short and straight as possible,
including neutral and ground. If using a breaker, use a
breaker position closest to SPD and panel’s neutral &
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.
• Never Hi-Pot test any SPD. Product will fail prematurely.
• Do not install the STXP through the bottom of a NEMA
3R panel. Dripping water will prematurely fail the SPD.
(A sealed pipe nipple installed in the SPD may be a
solution.)
1. Use voltmeter to check voltages and ensure correct
SPD. See Data Sheet for specs & wire-outs.
2. Determine mounting method (See Figure 3) – weather
resistant equipment may be required.
3. If SPD has optional Dry Contact, pre-plan its installation.
4.
Remove power from panel/source. Confirm panel and
all sources are de-energized.
5. Identify breaker location and SPD location. Position
SPD such that LED is best visible.
6. Mount SPD – weather resistant applications require
additional sealing, o-rings, etc. (not included).
• Remove an appropriately sized knockout from panel.
• Connect conductors as appropriate – short and
straight as possible (Hi-Legs are Phase B).
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 confirm proper operation of green LED
indicator and/or options.
