Siemens TPS3 11 user manual Poor Engagement Conduit needs to be threaded in farther

VCAUTION

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.

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.

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:

CORRECT INSTALLATION

Threaded 6 Full Turns

INCORRECT INSTALLATIONS

•	Meet all National and Local codes (NEC® Article 285 addresses
	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® and clear of faults before
	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

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.
