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

Connect the chassis ground of the device to the switchgear
earth ground using a dedicated wire greater than 2 mm
