Terminal Strips
There are 3 groups of current terminal strips. There will be another terminal strip if the
meter is connected with the I/O module.
Safety Earth Connection
Before setting up the meter’s wiring, please make sure that the
switchgear has an earth ground terminal. Connect both the
meters and the switchgear’s ground terminal together.
This ground terminal symbol is used in this user’s manual.
