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

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.
