Prior to Running the DC Generator
The following checklist is intended to ensure dependable DC genset and watermaker
operation. Please follow the instructions carefully to ensure proper system performance.
Electrical Connections
Proper wiring connections are essential to genset operation. Ensure that all electrical
plugs are properly plugged in, wiring is complete, and fuses on engine are in place and
functional. Make sure that electrical plugs at the engine location are well protected against
water intrusion, and that all connections are secured so they can't fall into puddled water
or other sources of electrical danger. Plugs may be hermetically sealed with black
electrician's tape to add protection against water intrusion. In some installations, it may be
necessary to secure wiring with wire ties to minimize chafing and vibration.
High Output Alternator Cabling
Secure terminal connections and properly-sized cable runs are a necessity for charging
efficiency and system health. Ensure that both positive and negative output terminals from
the alternator are properly sized, based on the length of run. A 3% loss wiring chart is
included in the manual for the Max Charge regulator. Keep in mind that sizing should be
based on the round-trip distance between the alternator and the batteries being charged.
Both positive and negative cabling must be equally sized to support charging amperage.
The cabling between the alternator and battery bank
must be protected with a fuse or circuit breaker, as
outlined in ABYC electrical standards. Fusing must
exceed the output potential of the alternator. Ensure
that wiring is properly secured and is protected against
chafing. Wire ties or wire-relief fasteners should be
utilized at the genset to support the weight of the heavy
output wiring. This relieves the strain of the cable
connections at the alternator terminals, as copper
connectors may become loosened with engine
vibration.
