Pre-Install Notes
READ ALL WARNINGS BEFORE ANY SERVICE OR TESTING
Do not install, make any adjustments, or replace any components inside the
enclosure with the power supply turned on. Under certain circumstances,
dangerous potentials may exist even when the power supply is off. To avoid
casualties, always turn the main power supply off before performing maintenance
and/or testing.
HAZARD OF ELECTRIC SHOCK, BURN, OR EXPLOSION
CAUTION
The installation of a surge protection device (SPD) must be done by qualified
electrical personnel. A SPD must be grounded through the power system ground
for proper operation.
WARNING
Before installing the suppressor, AC power must be OFF. Failure to do so could
result in damage to the suppressor and poses a potential electrical shock hazard to
personnel. Always use a properly rated voltage sensing device to confirm that power
is off.
Read SPD label on side of the enclosure to verify voltage configuration.
Discontinue installation if the measured voltage is not in the range of the model
voltage configuration of the SPD being installed. Contact LEA International
technical support with any questions concerning the voltage configuration prior to
installation and application of power.
Perform such work only after reading and understanding all of the instructions
contained in this manual.
Beware of potential hazards, wear personal protective equipment and take
adequate safety precautions.
Before performing visual inspections, tests, or maintenance on the equipment,
disconnect all sources of electric power. Assume that all circuits are live until they
have been completely de-energized, tested, grounded, and tagged. Pay particular
attention to the design of the power system. Consider all sources of power,
including the possibility of back feeding.
Handle this equipment carefully and install, operate and maintain it correctly in
order for it to function properly. Neglecting fundamental installation and
maintenance requirements may lead to personal injury, as well as damage to
electrical equipment or other property.
Carefully inspect your work area and remove any tools and objects left on /or in the
enclosure.
Replace all devices and covers before turning on the power to this equipment. All
instructions in this manual are written with the assumption that the customer has
taken these measures before performing installation or testing.
Failure to follow these instructions could result in DEATH or
serious injury.

Installation Procedure
Notes
Please read the entire installation manual before installing this SPD. Carefully
unpack the SPD, removing all packaging material. Inspect for any signs of damage
that may have occurred during shipment. If any damage is found, stop installation
and contact LEA International.
The SPD should only be installed by a licensed electrician.
All local and National Electric Codes must be observed.
Verify the voltage configuration on the SPD label matches the actual system voltage
configuration of service point.
For optimal SPD performance, verify that earth ground resistance is less than 25
ohms (per NEC).
Before installation, shut off power to prevent accidental electrical shock or injury.
Make sure all conductors are sized appropriately for this SPD.
Mounting
The SPD should be mounted as close as possible to the connection of service point.
The SPD is mounted using the four mounting holes located near the enclosure
corners.
Electrical conductors should enter the top of the SPD enclosure, or on either side
near the top of SPD enclosure.
Electrical conduit should be of sufficient size per NFPA 70 and National Electrical
Code. For optimum SPD performance, conduit with no sharp bends.
Conductor Size
Terminal Block
The lugs accept phase and Neutral conductors #8 to #1/0 AWG,
the Neutral and Safety Ground accept #8 to #1/0 AWG.
All conductors recommended to be insulated stranded copper greater than #6
AWG diameter.
Disconnect
The disconnect switch lugs accept phase conductors #10 to # 4 AWG,
the Neutral and Safety Ground accept #8 to #1/0 AWG.
All conductors recommended to be insulated stranded copper greater than #6
AWG diameter.

AC Power Connection
The SPD is installed in parallel with the incoming phase conductors.
It is recommended to connect the SPD to a 60A circuit breaker. This allows for
servicing of the SPD without shutting power off at the panel main breaker.
Route all SPD conductors taking care to avoiding sharp bends and keeping all leads
as short as possible, not exceeding five feet (5’).
To ensure optimum SPD performance, verify that all electrical connections are clean.
Connect the phase and neutral wires to the terminals marked Phase 1, Phase 2,
Phase 3, and Neutral.
Connect the green safety ground wire (building ground system) to the Safety Ground
lug.
Tighten all connections to the recommended torque value.
Remote Alarm Connection
The SPD offers one set of dry contacts for remote alarm monitoring. These screw
terminal connections are located on the PC board as shown on Pages 8 or 10. The
three connections are labeled NC (Normally Closed), NO (Normally Open) and C
(Common).
Remote Alarm Contact Maximum Ratings:
125 Vdc / 0.24 A
125 Vac / 0.5 A
30 Vdc / 2.0 A
Final Check
Apply AC power to the SPD.
The SPD TVSS Status LED should be illuminated green.
If the TVSS Status LED is red or not illuminated, contact LEA International’s
technical support at 800.882.9110.
If the Alarm Disabled LED is red, press the audible alarm Enable button to Enable
the audible alarm. The Alarm Disabled LED will turn dark

.
Troubleshooting
The SPD operational status can be seen on the front door of the enclosure. There is
no need to open the unit for any reason.
TVSS Status LED
A green LED indicates power is applied and all SPD protection modes are normal.
A red LED indicates the SPD needs servicing.
Surge Counter
Surge Counter Display
The LCD display indicates there was an event and has recorded the number of
surge/transients events since the counter has been reset.
If the surge counter display is blank, the battery may be defective or dead. Please
contact LEA Technical support.
Counter Reset button
Press to reset the surge counter to zero.
Audible Alarm
Alarm Disabled LED
A dark LED indicates the audible alarm circuit is enabled.
A red LED indicates the Audible Alarm has been silenced and serves as a reminder
that the SPD needs to be serviced.
Audible Alarm Disable button
Press to turn off the audible alarm. The Alarm Disabled LED will turn red and
serves as a reminder that the SPD needs to be serviced. If the SPD has been
severely damaged disconnect power to the SPD using the circuit breaker or
disconnect switch to silence the alarm.
Maintenance of electrical devices should be done only by trained professional
electrician.
Audible Alarm Enable button
Press the Enable Button for the audible alarm. The Alarm Disabled LED will turn
dark
Maintenance
The SPD should be scheduled for periodic inspection to ensure the SPD is
operational and all wire connections are tight.
If the SPD needs replacement, please contact LEA International for replacement at
800.882.9110 or online at www.protectiongroup.com.
