CAUTION
V
CONDUCTING DIELECTRIC AND/OR
HI-POTENTIAL TESTING WILL CAUSE
INTERNAL DAMAGE TO TPS3 UNIT.
Do not perform dielectric or high potential
tests with the TPS3 unit installed.
TPS3 11 Installation Instructions
Common Problems to Avoid
•
Confirm System voltage to SPD voltage (120V SPD will fail instantly
on 240V, 277V, etc.)
•
Locate SPD close so leads are short & straight as possible (or will
seriously hurt performance)
•
Make sure N-G or XO bonding meets NEC® (or will prematurely fail
SPD)
•
Energize SPD AFTER system is stabilized & checked (inadvertent system
problem may fail SPD)
•
SPDs are regulated by NEC®Article 285 and UL 1449
•
Never Hi-Pot test any SPD (will prematurely fail SPD)
Pre-Plan your installation. You will need to accomplish the following:
•
Meet all National and Local codes (NEC
SPDs)
•
Mount SPD as close to panel or equipment as possible to keep leads
short
•
Ensure leads are as short and straight as possible, including neutral
and ground. Consider a breaker position that is closest to the SPD and
the panel's neutral & ground
•
Suggested breaker & conductor size is 50A-30A with 8 AWG
•
Make sure system is grounded per NEC
energizing SPD.
1. Use a voltmeter to check all voltages to ensure correct SPD
2. If unit has Flush Mount option refer to Flush Mount Installation
Instructions following
3. If SPD has Dry Contact pre-plan its installation
4. Remove power for panel. Confirm panel is deenergized.
5. Identify breaker location and SPD location
6. Remove an appropriately sized knockout from panel
7. Mount SPD, use appropriate weatherproofing equipment as
needed
8. Connect conductors as appropriate – short and straight as possible
(Note that Hi-Legs are Phase B)
9. Label or mark conductors as appropriate (neutral: white, ground:
green, energized: black, hi-leg: orange)
10. 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)
11. Energize and confirm proper operation of indicators and/or
options
A sealing O-ring is provided. SPD can be chase-nipple mounted (nut
is provided).
Note that any conduits must be installed correctly.

V DANGER
Hazardous voltage.
Will cause death or serious injury.
Keep Out.
Qualified personnel only.
Disconnect and lock off all power before
working on this equipment.

6 full turns required
•
Use closest breaker to SPD
•
Locate SPD close to intended
breaker
•
Keep Leads Short as Possible
•
Avoid Sharp Bends
•
Rotate TPS3 11 such
that LED indicator is
most visible
•
Outdoor installation requires
appropriate weather sealing at
nipple (o-ring, sealing conduit,
etc.)
