General Installation Guidelines
The valid wiring schemes are as follows:
Class B (meter accuracy: ±1%). AC grid-side lines are connected to the upper terminal
blocks of the inline meter.
Class A (meter accuracy: ±2%). AC load-side lines are connected to the upper terminal
blocks of the inline meter.
NOTE
The difference between accuracy classes A and B results from the differing
current path through the meter in each scheme. For best performance, choose
Class B if possible.
General guidelines for installing the inline meter:
1. Turn off the AC power (main circuit breakers) before connecting the inline meter.
2. Using one of the below wiring schemes, connect the AC wiring to the terminal
blocks at the top and the bottom of the inline meter.
NOTE
Insert a flat-head screwdriver in the dedicated slot to open the screw covers.
Use cable with a cross-section of 1.0 - 26.0 mm
CAUTION
DO NOT use a circuit breaker with a rated current of more than 65A.
