DANGER: Electrical shock or burn hazard.
Installation of Secondary Surge Protector should be
made by qualified personnel. Failure to lockout
electrical power during installation or maintenance can
result in fatal electrocution or severe burns.
1. Disconnect and lockout power to the point where the
Secondary Surge Protector (EPD unit) is to be installed.
Follow all applicable electrical codes & procedures.
CAUTION: Check to make sure line voltage does
not exceed EPD unit voltage requirement. These
EPD units do not have overcurrent protection, and
should be fed from an appropriately sized breaker (<= 30A).
2. Mount the EPD unit as close as possible to the sensitive
electronics being protected. See FIG. 3.

its ratings and the unit should be replaced immediately as
no protection may be provided.
