Siemens TPS3 09 Sheet for specs & wire-outs, May be required, To not drop SPD into wall

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 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)

•Use closest breaker to SPD

•Locate SPD close to intended breaker

•Keep Leads Short as Possible

•Avoid Sharp Bends

• Do not install the TPS3 09 through the bottom of a NEMA

3R panel. Dripping water will prematurely fail the SPD.

1. Use voltmeter to check voltages and ensure correct SPD. See Data

3.	If SPD has optional Dry Contact and Flush Mount Kit, pre-plan
	their installation. See Figures 4&6. (If flush mounting, be careful

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)
		Note that the metallic connection hub is not grounded within the SPD
		and proper grounding requires connection of the green conductor
		ground.
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.
