WARNING: HIGH LEAKAGE CURRENT. EARTH CONNECTION
ESSENTIAL BEFORE CONNECTING SUPPLY.
The main electronics are stationary pluggable equipment Type A with simultaneous multiple connections to

● The building installation must provide a means for connection to protective earth.
● The equipment must be connected to that means.
● A service person must verify that all socket outlets from which the equipment is to be powered
provides a connection to the building protective earth.
To verify, use a suitable long test/wander lead with an ohm meter/multimeter. Connect one end to a
known protective earthing point of the building electrical installation and ensure that there is a reading
of less than one ohm to each earthing contact of all socket outlets to be connected, as shown next.
Socket outlets earthing contact points
If lack of protective earth is discovered at any of the socket outlets, this must first be rectified by
installing a suitable protective earthing conductor in accordance with local wiring code and
regulations. This installation must be carried out by a registered, competent electrician.
