DC Genset / WatermakerPre-Run ChecklistPrior to Running the DC GeneratorThe following checklist is intended to ensure dependable DC genset and watermakeroperation. Please follow the instructions carefully to ensure proper system performance.Electrical ConnectionsProper wiring connections are essential to genset operation. Ensure that all electricalplugs are properly plugged in, wiring is complete, and fuses on engine are in place andfunctional. Make sure that electrical plugs at the engine location are well protected againstwater intrusion, and that all connections are secured so they can't fall into puddled wateror other sources of electrical danger. Plugs may be hermetically sealed with blackelectrician's tape to add protection against water intrusion. In some installations, it may benecessary to secure wiring with wire ties to minimize chafing and vibration.High Output Alternator CablingSecure terminal connections and properly-sized cable runs are a necessity for chargingefficiency and system health. Ensure that both positive and negative output terminals fromthe alternator are properly sized, based on the length of run. A 3% loss wiring chart isincluded in the manual for the Max Charge regulator. Keep in mind that sizing should bebased 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 bankmust be protected with a fuse or circuit breaker, asoutlined in ABYC electrical standards. Fusing mustexceed the output potential of the alternator. Ensurethat wiring is properly secured and is protected againstchafing. Wire ties or wire-relief fasteners should beutilized at the genset to support the weight of the heavyoutput wiring. This relieves the strain of the cableconnections at the alternator terminals, as copperconnectors may become loosened with enginevibration.- 20 -Oil fill / dipstick locations.
