BREAKER
(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 SPD ee such
that LED indicator
is most visible
▪ Outdoor installation requires appropriate weather
sealing at nipple (gasket, sealing conduit, etc.)
To Protected Loads

Sealing gasket:
two choices
1.) At 3/4" nom.
thread: ID is 1.05"
2.) At 0.14" high 'base
step': ID is 1.25"

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 substantially).
▪ 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 & 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).
1. Use voltmeter to check voltages and ensure correct SPD. See Data Sheet for specs and wire-outs.
2. Determine Mounting method (See Figure 5) – weather resistant equipment may be required.
3. If SPD has optional Dry Contact, pre-plan its installation.
4. Remove power from panel/source. Conrm panel/source is deenergized.
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 conrm proper operation of green LED indicator and/or options.
(Afx supplemental label accessory if appropriate. See Figure 5.)

WARNING
▪ Conrm XO N-G Bonding at Upstream Transformer
▪ Do Not Hi-Pot Test
▪ Resulting Damage is not Covered Under Warranty
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.
