CAUTION! 30A MAX.
STATUS INDICATOR
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.
3. For mounting, use layout of holes as indicated in FIG. 1;
drill 9/64 diameter holes in the mounting surface for the
#8 x 1/2-lg. screws provided.
4. Output wires should be kept as SHORT as possible
between equipment and the EPD unit, and the input and
output wires should be twisted to minimize noise
coupling.
5. Input and output wires to and from the EPD unit should
be separated to minimize noise coupling.
6. Use A.A.R. hardware supplied. See FIG. 2 for assembly.
7. The LED on the front panel illuminates to indicate that
the protection circuitry is operating correctly. If LED has
extinguished, the EPD unit has sustained a surge beyond
its ratings and the unit should be replaced immediately as
no protection may be provided.
8. Engage power to the EPD unit. Status LED should
illuminate indicating correct operation. If not, disconnect
power, check wiring, rectify any deficiencies, and reapply
power. If still experiencing difficulties, please contact
your supplier, or the manufacturer:
