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.

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.

•
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.
