INSTALLATION AND SERVICE OF ELECTRICAL SERVICES ARE TO INSTALL
AND SERVICE THIS EQUIPMENT. HAZARDOUS VOLTAGES ARE PRESENT
INSIDE THE SPD MAX SERIES ENCLOSURE DURING NORMAL OPERATION.
FOLLOW ALL SAFE WORK PRACTICES AND LOCK OUT TAG OUT PROCE-
DURES TO AVOID ELECTRICAL SHOCK AND ARC FLASH.
In the event of a loss of protection, one or more “Replace” red
LED(s) will light on the front display (See Figure 1 showing Phase
B green Protected LED is out and the red Phase B Replace LED
is lit) and, if equipped, an audible alarm will sound. To silence the
alarm, push in Alarm Silence on the front display. The red LED(s) will
remain lit until power is disconnected or the unit has been properly
serviced.

1.0 Determining Which SPD Device Has Lost
Protection
If the SPD Max Series device has a Catalog number ending in a R,
T, V or X, such as SPMxxxxxxxxR, your device contains one inter-
nally mounted Surge Protective Device (SPD1). Record the Catalog
number of the SPD Max Series device and contact your local Eaton
Distributor to order a replacement SPD or call the Eaton Customer
Support Center at 1-800-809-2772, Option 4, Sub-Option 2 for techni-
cal support.
If the SPD Max Series device has a Catalog number ending in a
S, U, W or Y, such as SPMxxxxxxxxS, your device contains two
internally mounted Surge Protective Devices (SPD1 and SPD2). To
determine which SPD(s) has lost protection open the hinged door of
the SPD Max Series enclosure by loosening, but not removing, the
7 screws holding the metal latches. Carefully open the enclosure
door, but DO NOT OPEN the hinged dead front panels, secured by
four metric TORX®head screws, within the enclosure because live
wires are located under the hinged dead front panels. In the center
of the enclosure is the SPD Status indicator (See Figure 2). A red
LED indicates whether SPD1, SPD2 or both SPD1 and SPD2 have
lost protection. Record the Catalog number of the SPD Max Series
device and contact your local Eaton Distributor to order a replace-
ment SPD or call the Eaton Customer Support Center at 1-800-809-
2772, Option 4, Sub-Option 2 for technical support.

2.0 Conrm SPD Replacement Part Number
Before Proceeding
Before proceeding, go to Appendix A and confirm the SPD replace-
ment part number you received matches the SPD Max Catalog Part
Number and SPD replacement part number listed in Appendix A. If
there are any discrepancies contact the Eaton Customer Support
Center at 1-800-809-2772, Option 4, Sub-Option 2.
The SPD Max Series device comes equipped with either an installed
30 Amp circuit breaker or a power terminal block. If the SPD Max
Series enclosure has a Catalog number ending with a R, S, V or W,
such as SPMxxxxxxxxR, the enclosure contains one 30 Amp circuit
breaker and the SPD Max can be locked out within the enclosure to
disconnect power to the load side of the breaker where the SPD(s)
are terminated. If an upstream disconnect is available, it should also
be opened. Proceed to 3.0 SPD Max with Circuit Breaker.
If the SPD Max Series enclosure has a Catalog number ending with
a T, U, X or Y, such as SPMxxxxxxxxT, your enclosure contains a
power terminal block and the SPD Max enclosure must be locked
out at the upstream disconnect. Proceed to 4.0 SPD Max with
Terminal Block.

3.0 SPD Max with Circuit Breaker
1. Open the hinged door of the SPD Max Series enclosure by loos-
ening, but not removing, the 7 screws holding the metal latches.
2. Carefully open the enclosure door and look at the SPD Status to
determine which SPD(s) needs to be replaced. If the SPD Max
only contains one SPD module there isn’t a SPD Status indicator
module mounted in the center of the dead front panel. A red
LED indicates whether SPD1, SPD2 or SPD1 and SPD2 has lost
protection. DO NOT OPEN the load side hinged dead front
panel located within the enclosure that is secured with two
Torx®screws until the circuit breaker within the SPD Max
device has been switched to the OFF position and the locked
out/tagged out procedure has been completed in accordance
with the National Electric Code (NEC), Canadian Electric
Code (CEC), state and local codes, or other applicable coun-
try codes.
3. Disconnect the SPD Status ribbon cable of the specific SPD(s)
which is being replaced by loosening ~½ turn, but not remov-
ing, the Cable Hold Down Bracket(s) screws. Once the screws
have been loosened the bracket(s) can be slid up to gain access
to the ribbon cable connectors(s). Carefully, unplug the ribbon
connector(s) using a pair of long nosed pliers.
4. If the SPD Max has two SPDs mounted within the enclosure
also unplug the SPD Status ribbon cable connector of the SPD to
be replaced (See Figure 3).

 WARNING
ONLY LICENSED/QUALIFIED ELECTRICIANS WHO ARE TRAINED IN THE

AND SERVICE THIS EQUIPMENT. HAZARDOUS VOLTAGES ARE PRESENT
INSIDE THE SPD MAX SERIES ENCLOSURE DURING NORMAL OPERATION.
FOLLOW ALL SAFE WORK PRACTICES AND LOCK OUT TAG OUT PROCE-
DURES TO AVOID ELECTRICAL SHOCK AND ARC FLASH.
5. Remove and retain the two Torx®screws securing the load side
dead front hinged plate (See Figure 3). If the SPD Max is wired
with the optional Form C for remote monitoring remove the Form
C three pin connector located on the right side of the SPD. If
the SPD Max is equipped with two SPD modules and the Form
C connectors are being used in both modules then both connec-
tors must be removed before the load side Dead-Front can be
lifted. If the Form C option is not connected to field wiring, the
connector(s) do not need to be removed prior to lifting the Dead-
Front panel.
6. Open the load side hinged dead front panel to gain access to the
load side wiring compartment (See Figure 4).

any of the circuit breaker load terminals with the appropriate
meter or voltage indicator verify that no voltage is present in any
of the load side wiring.
8. Then loosen the circuit breaker terminal screws (~ 10 turns) to
remove the phase wires from the circuit breaker.

4.0 SPD Max with Terminal Block
If the SPD Max Series enclosure has a Catalog number ending with
a T, U, X or Y, such as SPMxxxxxxxxT, the enclosure contains a power
terminal block and the SPD Max enclosure must be locked out and
tagged out at the upstream disconnect or Source Power from the
unit. Before proceeding, verify and record which Surge Protective
Device within the SPD Max Series enclosure, SPD1, SPD2 or SPD1
and SPD2 are to be replaced before turning power off to the SPD
Max Series enclosure at the upstream disconnect or Source Power
(Refer to the section “Determining which SPD device has lost pro-
tection”, if necessary). Once this has been recorded, Lock Out and
Tag Out power to the SPD Max enclosure in accordance with
the National Electric Code (NEC), Canadian Electric Code (CEC),
state and local codes, or other applicable country codes.
1. Open the hinged door of the SPD Max Series enclosure by loos-
ening, but not removing, the 7 screws holding the metal latches.
Carefully open the hinged door (See Figure 8).
2. Disconnect the SPD Status ribbon cable of the specific SPD(s)
which is being replaced by loosening ~ 1/2 turn, but not remov-
ing, the two Cable Hold Down Bracket(s) screws(See Figure 8).
