▪ Feed all wires into the box via an appropriate gland and connect. The Earth wire from
the power lead must be earthed to the casing using a proper terminal.
▪ Replace the lid making sure the gasket is in place and clean and that no wires have
been pinched.
External Earthing
Where required, earth the C5000 Power Supply using an earth wire with a cross sectional area
at least equal to the largest conductor. The earth wire is attached to the integrated point.
Cable requirements are as follows:
Power
3 Core Steel Wire Armour Cable 2.5mm
2
,
220 - 240 Volts. 50 Hz, +/-10%
Core 1: 230 Volt Supply (Active).
Core 2: Neutral.
Core 3: Earth.
Dispenser: 25w Idle, 200W with all solenoids active.
Submersible pump(s): Suitable cable for 230V solenoid switching current. 300mA maximum
load.
Do not wire submersible pumps directly to C5000 power supply.
Comms
2 Core Steel Wire Armour Cable 1.5 mm
2
. Maximum cable length 100 m. 12 V current loop.
Make sure that there is at least a two metre cable tail on both the incoming underground 230 V
and comms cables to reach the C5000 flameproof box.
