9 Connecting to a power supply
This pump is fitted with a switch mode power supply and will operate from any mains
voltage in the range ~100-240V AC, 50/60Hz supplies.
Make suitable connection to an earthed, single-phase mains electricity supply.
We recommend using commercially available supply voltage surge
suppression where there is excessive electrical noise.
Power cable: The pump is supplied fitted with a cable gland and approximately
1.8m (5.9ft) of power cable.
Each pump is supplied with a power cable. The connector at the pump end of the
cable is IP66 rated. The mains plug at the opposite end of the cable is NOT IP66
rated.
Ensure that all power supply cables are adequately rated for the
equipment.
The pump must be positioned so that the disconnection device
(the mains plug), is easily accessible when the equipment is in
use.
When PAT testing this unit ensure that the earth bond test
terminal is used.
