WIRING
All power, input and output (I/O) wiring must be in accordance
with Class I, Division 2 wiring methods and in accordance with
the authority having jurisdiction. Electrical connections are made
via pluggable spring-clamp terminal blocks. It is recommended
that the power supplied to the meter be protected by a fuse or
circuit breaker.
When wiring the meter, refer to the label on the unit for pin-out
numbering against those shown in the wiring drawings for proper
wire position. Strip and connect the wire according to the
terminal block specifications on Page 3. Use a small screwdriver
to press down on tab next to the terminal position to open the
spring clamp. Insert the wire into the terminal position and then
remove the screwdriver to engage the spring-clamp.
POWER WIRING
Must use a Class 2 circuit according to
National Electrical Code (NEC), NFPA-70 or
Canadian Electrical Code (CEC), Part I, C22.1 or
a Limited Power Supply (LPS) according to IEC/
EN 60950-1 or Limited-energy circuit according
to IEC/EN 61010-1.

CAUTION:
Sensor input common is NOT isolated from user input common. In order to preserve the safety of the controller
application, the sensor input common must be suitably isolated from hazardous live earth referenced voltages; or input common must
be at protective earth ground potential. If not, hazardous live voltage may be present at the User Inputs and User Input Common
terminals. Appropriate considerations must then be given to the potential of the user input common with respect
to earth common, and the common of the isolated plug-in modules with respect to input common.
