Maintenance and service

Field Service Considerations

In the unlikely event that a unit should fail, it will generally be ser viced by exchanging the unit

for a replacement unit. The initial installation should be done in a way which makes this as

convenient as possible.

1. I t is good practice that a current transformer shor ting block is ﬁtted, this enables the meter to

be disconnected without open circuiting the current transformers. The shor ting block should be

wired so that the protective relays are not aﬀected.

2. All wiring should be routed to allow easy removal of the connection to the terminals.

Disconnect From Supply

A suitable isolator for both voltage and current terminals shall be included in the wiring

installation, close to the meter with easy access and marked as the meters disconnect device.

If the equipment is used in a manner not speciﬁed by the manufacturer the protection provided

by the equipment may be impaired. Current measuring terminals are not intended to be

connected to voltages to ear th above 50Vac.
