a) provide a cut out hole on the switchgear and
control panel according to DIN43700/ANSI
C39.1 as shown in Fig 4.
b) insert the meter through the hole and slide in the
retainer clip along the slots on both sides of the
power meter until the device is tightly secured on
the switchgear and control panel. The direction
and orientation of the retainer clips is shown in
Fig 3. The retainer clip can be removed by lifting
the tab lightly at the handle end.
c) remove the detachable terminal block from
the voltage input connection and connect the
metering voltage inputs to the detachable
terminal block as shown in Fig 5 according
to the wiring schemes shown in Figs 6 to
9 below. The recommended wire size is
AWG16~22.
Please make sure the power to
the voltage metering input is totally
removed.
Shunt any unused metering voltage
input to the N input connection

Metering voltage input detachable terminal block
connections
Upon completing this step, please insert the
detachable terminal block securely into the
voltage input connector housing.
The terminal block must be inserted
securely into the connector housing
on the meter to prevent improper
operation.
d) connect the metering current input to the current
input terminal block as shown in Fig 10 at page
12. The recommended wire size is AWG12~18.
Please make sure the power to the
current metering input is always
shunted. Under no circumstances
can the CT connections be left open
circuit. Use a CT shorting block if
necessary.
Never connect the metering current
input to the measured circuits
without using CTs.
Only use CTs complying with
IEC 61869 - 2
