TPS3 09 Installation Instructions
Pre-Plan your installation. You need to 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 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).
• Do not install the TPS3 09 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 location – weather resistant
equipment may be required.
3. If SPD has optional Dry Contact and Flush Mount Kit,
pre-plan their installation. See Figures 4 & 6. (If flush
mounting, be careful to not drop SPD into wall).
4. Remove power from panel/source. Confirm 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, 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
indicators and/or options.

BREAKER
• Use closest breaker to SPD
• Locate SPD close to
intended breaker
• Keep Leads Short as
Possible
• Avoid Sharp Bends
