Before installation as SPDe:
2.4 Wiring, for DC Units.
Step A:
Verify system voltage does not exceed maximum suggested operat-
ing voltage listed in table.
•
All voltage measurements should be completed with a DC volt-
meter.
•
DO NOT INSTALL SUPPRESSOR IF MEASURED VOLTAGE
EXCEEDS MAXIMUM SUGGESTED OPERATING LIMITS.

Step B:
Choose suppressor installation location so leads are kept as short
and straight as possible.
SUPPRESSOR MUST BE CONNECTED
TO ELECTRICAL SYSTEM VIA ONE OF THE FOLLOWING CIRCUIT
INTERRUPT DEVICESe:
•
1-Double Pole/Single Throw 30 Amp Circuit Breaker NOTE: Pre-
existing breakers of rated load size may be utilized if provisions
for multi-conductor connections are made according to N.E.C.110-
14A.
•
2-Single Pole/Single Throw 30 Amp Circuit Breakers
•
2-30 Amp Class RK5 Fuse(s) (Such as Bussmann FRN-R-30 for
less than 125 VDC)

Before Installation as Secondary Surge Arrestore:
Step A:
Follow 2.4 Wiring, for DC Units. Step A.
Step B:
No circuit interrupt device is required.
Installation Instructions as SPDe:
Step 1:
REMOVE POWER FROM ELECTRICAL SYSTEM BEFORE
INSTALLING SUPPRESSOR.
Step 2:
Mechanically mount suppressor:
•
Suppressor to be installed through panel knockout and via sup-
pressor optional (these are not on this unit)mounting feet. Place
suppressor against mounting surface and mark feet positions if
applicable. Complete conduit connection installation. Screw box to
surface with appropriate screws.
•
Assure weatherproof conduit and fittings are used to maintain
NEMA 4 rating.
•
Suppressor to be mounted for shortest and straightest possible
wire installation from suppressor to system bus. Excessive wire
length and sharp bends degrade suppressor performance; there-
fore, avoid excessive wire length and sharp bends when at all
possible.
•
If installing on a system other than electrical panel, mount in close
proximity to system being protected using necessary means for
mounting.
otee:
N
A CIRCUIT INTERRUPT DEVICE IS STILL REQUIRED WHEN
INSTALLING SUPPRESSOR ON A SYSTEM OTHER THAN ELECTRICAL
PANEL.
•
Suppressor contains no position-oriented components and can be
mounted upside down or sideways.
Step 3:
Wire suppressor into electrical system:
•
Cut wire(s) as short as possible for optimum suppressor perfor-
mance.
•
Connect GROUND (Green) wire to system ground bus bar.
•
Connect Red wire to “+” and Black wire to “-”.
Step 4:
Apply power to system. Indicator light should glow. If light does not
glow, remove power and contact supplier.
Installation Instructions as Secondary Surge Arrestore:
Step 1:
Follow steps 1 through 4 above, only circuit interrupt device not
required.
