Connect the Power Supply
WARNINGS
1. MAINS SUPPLY VOLTAGES (220-240 V AC) ARE PRESENT IN THIS EQUIPMENT, WHICH MAY CAUSE
DEATH OR SERIOUS INJURY BY ELECTRIC SHOCK. ONLY A QUALIFIED ELECTRICIAN OR INSTALLER
SHOULD CONNECT THE POWER SUPPLY TO THIS UNIT.
2. THIS UNIT MUST BE CORRECTLY EARTHED.
This unit is designed for operation from a single-phase alternating current source (220-240V AC). A 2m cable is
connected internally to the unit for connection to an Isolator switch.
N.B. The unit must be wired so that all of the
conductors can be isolated from the mains supply, with a minimum 3mm gap between the contacts.
To connect the power supply:
1.
Ensure the local AC power supply is switched off.
One end of the power cable supplied is already connected to the unit.
Connect the other end of the cable to the switched fused spur.
Use cable clamps and clips to secure the cable, as appropriate.
If the LS core of the mains cable is not used it should be terminated in an appropriate manner.
