Eaton SPD Series

Surge Protective Device for Integrated Units

Instruction Manual IM01005019E - Rev. 5

1.5 Equipment Testing

WARNING

CONDUCTING DIELECTRIC, MEGGER, OR HI-POTENTIAL TESTING

WITH THE SPD INSTALLED WILL CAUSE INTERNAL DAMAGE TO THE

SPD. THE SPD WILL ALSO CAUSE THE TEST TO FAIL.

Every Eaton SPD Series unit is tested at the factory for dielec-

tric breakdown. No further SPD testing is required for installa-

tion.

If you desire to test distribution equipment by performing

dielectric, megger, or hi-potential tests, any installed SPD must

be disconnected from the power distribution system to prevent

damage to the unit.

Follow this procedure to safely disconnect the SPD:

1. Remove bus connected SPDs completely from the instal-

lation prior to performing any form of hi-potential testing.

2. Isolate SPDs connected via conductors as follows:

a. 3-wire delta SPDs: Turn off the circuit breaker to

isolate the SPD, if connected through a circuit

breaker.

b. Wye connected SPDs: Turn off the circuit breaker and

remove the Neutral connection.

3. Remove MCC units with SPDs from the MCC structure.

2.0 Installation

WARNING

INSTALLING AN SPD THAT IS IMPROPERLY RATED FOR THE ELECTRI-

CAL SYSTEM VOLTAGE COULD CREATE A POTENTIALLY HAZARDOUS

CONDITION, RESULTING IN INJURY OR EQUIPMENT DAMAGE.

2.1 Preparation for Installation

CAUTION

EATON SPD SERIES PRODUCTS MUST BE INSTALLED OR REPLACED

BY A QUALIFIED ELECTRICIAN TO AVOID INJURY OR EQUIPMENT

DAMAGE.

Before installing an Eaton SPD Series unit, do the following:

•

Verify that the area is clear of any dirt, debris or clutter that

may hamper the installation process.

•

Verify that there is enough space in the cabinet or MCC to

install the SPD. See Section 2.3, "Installation Procedures" for

dimensions.

•

Confirm that all tools and equipment needed for the installa-

tion are available.

•

Confirm that the system voltage and wiring configuration is

the same as the SPD you are installing. Check the voltage

rating label on the front left side of the SPD. See Figure 1.

WARNING

TURN OFF THE POWER SUPPLY BEFORE WORKING IN ANY ELECTRI-

CAL CABINET OR ON ANY CIRCUIT BREAKER PANEL. FAILURE TO DO

SO COULD RESULT IN INJURY OR DEATH FROM ELECTRICAL SHOCK.

NOTICE

A POOR GROUND, OR GROUNDING/BONDING VIOLATIONS, COULD

PREVENT THE SPD FROM PERFORMING AS SPECIFIED.

DO NOT USE THE SPD TO CARRY OR PASS THROUGH GROUND TO

OTHER DEVICES OR LEADS. DAMAGE TO THE EQUIPMENT MAY

RESULT.

•

Check the facility grounding system. All grounding, bonding,

and earthing must meet the NEC and any other national, state

and local electrical codes.

2.2 Installation Locations

Eaton's SPD Series can be installed directly to the bus for

Panelboard applications.

The SPD can also be connected through a circuit breaker for

installations in Panelboards, Switchboards, Switchgear, MCC’s

and Busway applications.

Follow these guidelines to determine the best location for

mounting this product.

2.2.1 Direct Bus Mount Applications

•

Install the SPD on the load side of the main breaker. Connect

the SPD directly to the bus located as close as possible to

the main breaker.

2.2.2 Connected Through a Circuit Breaker Applications

•

Install the SPD next to the first breaker after the incoming

main lugs or main breaker.

2.3 Installation Procedures

2.3.1 Direct Bus Mount Applications

1. Verify that the SPD you are about to install is rated

for the application voltage and system. See Table 5 in

Section 6, "Ordering Guidelines".

2. Follow all national, state and local electrical codes when con-

necting the SPD.

3. Before mounting the SPD, first determine the bus bar con-

figuration. If the panelboard uses an offset B-Phase bus bar

configuration, no action is required. If the panelboard uses a

coplanar bus bar configuration, remove the bus bar

extension bushing from the back of the SPD and discard.

See Figure 2.

4. Mount the SPD to the support brackets (customer supplied)

using #10 fasteners and tighten to 4.1 Nm (36 in-lbs). See

Figures 4 and 5 for mounting details.

5. Install the bus mount fasteners and tighten to 4.1 Nm (36

in-lbs). See Figure 3.
