MOUNTING
Choosing Mounting Hardware
As with any marine equipment, secure mounting is of utmost importance. You will need to provide four #8 bolts or
screws to secure the unit. The screws or bolts you choose should be backed with a flat washer and kept vibra-
tion-free with a split-ring lock washer. If using bolts, they must be secured on both sides of the bulkhead and also
backed with a washer or washer plate. If using screws, they should be at least 1” long. All hardware must be cor-
rosion-resistant stainless steel or cadmium-plated steel.
Mounting the Alternator Regulator
The regulator is protected against ambient humidity, but must be mounted in a dry location free of moisture, dust,
and other environmental insults. The regulator will operate in temperatures to 140
F (60
C).
Use care when drilling to avoid contact with any wires or live components.
