PREPARATION
DANGER: Electrical shock or burn hazard.
Installation of Primary 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 breaker box (load
center) or point where the Primary Surge Protector is to
be installed. Follow all applicable electrical codes &
procedures.
CAUTION: Verify line voltage does not exceed
Surge Protector voltage requirement.
PROTECTOR MOUNTING AND LOCATION
2. The Surge Protector is to be mounted directly to the
breaker box, to keep the wiring as SHORT as possible.
The Surge Protector can be mounted on the top, the
bottom, or the side of the load center, see FIG. 4. In
general, it would mount on the side, immediately
adjacent to the two pole breaker which will feed it. If
physical obstructions prevent this, then the top or bottom
mounting positions can be used.
3. Having determined where the Surge Protector is to be
mounted, provide a knockout in the load center to receive
the ½” nipple provided as part of the Surge Protector.
4. If the load center metalwork is of sufficiently heavy
gauge, or the Surge Protector is being mounted to the top
of the load center, the Surge Protector may be supported
by the nipple alone. If this is the case, DO NOT perform
the outlined, shaded steps (steps 5, 7, 8 or 9).
5. Remove the screws holding the lid and base of the Surge
Protector together.
6. The base (or the complete Surge Protector if step 5 was
omitted) can then be butted up against the load center,
with the wiring and nipple fed into the load center. Using
the provided locknut, fasten the nipple in place inside the
load center.
7. Using the holes in the base of the Surge Protector as a
template, drill four 3/16 diameter pilot holes in the wall
surface.
8. Fix the base to the wall using the (4) #12 x 3/4-lg. screws
supplied. See FIG. 2
9. Replace the lid of the Surge Protector back onto the base,
and fix in position with the screws previously removed
(the screw adjacent to the load center may not be able to
be replaced).
10. Pull the wires firmly through into the load center to
remove any slack present.
AC ELECTRICAL CONNECTION
11. The Surge Protector is to be installed parallel to the load
center bus via a two pole circuit breaker. The circuit
breaker rating should be 20A or 30A.
12. Reference FIG. 3 or the front of the Surge Protector for
the wiring diagram. Connect the wire leads from the
Surge Protector, beginning with:
a) Ground (green/yellow wire) to ground bar
b) Neutral (white wire) to neutral bar
c) Line wires (black and red wires) to circuit breaker
NOTE: The green wire must be properly and securely
connected to system ground.
