Effective 2018-05-29 Bulletin No. CUB5 INST-A
Drawing No. LP1063
WIRINGOVERVIEW
Electrical connections are made via screw-clamp terminals located on
the back of the meter. All conductors should conform to the meter’s
voltage and current ratings. All cabling should conform to appropriate
standards of good installation, local codes and regulations. It is
recommended that the power supplied to the meter (DC or AC) be
protected by a fuse or circuit breaker.

The user input of the meter is
internally pulled up to +9 to +28 V
with 10 K resistance. The input is
active when it is pulled low (<1 .0 V).
Connect external switching device between the
User Input terminal and Input Common.

3.3INPUTWIRING
CAUTION: Power common (PWR COMMON) is NOT isolated from input common (INP COMM). In order to preserve the safety of the meter
application, the power common must be suitably isolated from hazardous live earth referenced voltage; or input common must be at protective
earth ground potential. If not, hazardous voltage may be present at the Signal or User Inputs and input common terminals. Appropriate
considerations must then be given to the potential of the input common with respect to earth ground; and the common of the plug-in cards with
respect to input common.
