Electrical Connections

Prior to pump installation ensure that there is at least a two-metre tail on the incoming

underground mains supply / pump contactor cable and comms cable (if comms enabled).

These cables are terminated at the C4000 power supply, which is housed in the flameproof

enclosure located in the bottom of the pump, behind the door.

Mains power wiring should be rated for a maximum current draw of 10 A rms at 220-240 V

ac.

Refer to AS/NZS 60079.14 for appropriate cabling.

When replacing the lid of the flameproof enclosure, ensure the sealing O ring is in place.

Note: All cables entering the power supply must be glanded with approved 20mm flameproof

glands.

Note: Output to submersible pump(s) is 230 V ac, 300 mA max. It is wired to the pump

contactor/relay at the switchboard and not directly to the pump.

Note: Pump comm's connect to pump controller such as DCA, CommunicatorController etc.

(option). Comms cable is not intrinsically safe.

Submersible Pump connections

8.1

Connect the feeds to the submersible pump relays / contactors to the C4000 Power Supply as

follows:

Pump supplying side A to terminal marked T1

Pump supplying side B to terminal marked T4

If both sides are required to switch the same submersible pump then T1 and T4 should be

linked together.

Note: Dispensers do not use the terminals marked LOAD 1 & 2.
