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.
