Field Service Considerations
In the unlikely event that a unit should fail, it will generally be serviced 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. It is good practice that a current transformer shorting block is fitted, this enables the meter to
be disconnected without open circuiting the current transformers. The shorting 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 earth above 50Vac.
