Maintenance - Whale BE9003(B) Instruction And Installation Manual

7.3 Wiring
WARNING: Fire hazard. Wiring must comply with applicable electrical standards and include a properly rated circuit breaker
(Fuse rating must be rated for the pump used in the system. Check the pump installation manual for the specific fuse size).
WARNING: Improper wiring can cause a fire resulting in injury or death.
NOTE: Switch off the power prior to making connections. Suggested wiring information is given as a guide only. For full
information, refer to the USCG, ABYC and ISO regulations for marine applications and wiring gauges, connectors and fuse
protection.
1. Follow the wiring diagram (Fig 3). All fuses and the circuit breaker must be properly rated for the bilge pump
within the circuit (see pump instruction manual for guidance). The maximum circuit breaker must be is 20 Amps.
NOTE: Do not use thermal circuit breakers with the BE9003(B)/BE9006(B). Magnetic breakers must be used.
2. The wiring is as follows:
• Manual terminal directly to
brown (+) pump wire.
• Automatic terminal to switch
brown/white stripe (+)
• Switch brown (-) to pump
brown (+).
• Black (-) pump wire to
negative battery terminal
3. Make all wiring connections above highest water level, using permanent waterproof terminals. Coat terminals with
liquid electrical tape.
