Electrical Power Supply
This equipment must be electrically isolated before removing the covers. Cables
connected to the volt free contacts may be supplied from another source and may
remain live after the unit is isolated. These must be isolated elsewhere.
All electrical connections must be carried out by a suitably qualified and competent
person.
The mains power supply to the pressurisation unit must be connected into the fused terminal block
as shown below:
On some larger models, the fused terminal block is replaced by a fused spur. If this is the case, the
power supply must be connected into the fused spur, as shown below:
It is recommended to supply power to the pressurisation unit via a lockable isolator.
This should be installed within 2m of the equipment.
This equipment can be damaged by the high voltages produced by electrical
installation testing equipment. When performing electrical installation tests, the
equipment must be isolated from the supply.
