Power Source Connection Power Source Connection Power Source Connection Power Source Connection
Before connecting your meter to the power source, check the label on the back of the
device to ensure that it is equipped with the appropriate power supply.
The power source can be dedicated-fused, or from a monitored voltage if it is within the
instrument power supply range.
AC power supply: connect the line wire to terminal 12 and the neutral wire to
terminal 10.
DC power supply: connect the positive wire to terminal 12 and the negative wire to
terminal 10.
Chassis Ground Connection Chassis Ground Connection Chassis Ground Connection Chassis Ground Connection
Connect the chassis ground of the device to the switchgear earth ground using a
dedicated wire greater than 2 mm
2 /14 AWG.
