WIRING DIAGRAM & INSTRUCTIONS

WIRING INSTRUCTIONS

7.  VOLTAGE INPUT : The input voltage should not exceed the rated input voltage (100V or 400V). Otherwise, consider using a potential transformer (PT).

8.  CURRENT INPUT : The standard rated input current is 5A. For currents greater than 5A, an external CT should be used. Ensure CT secondary circuits are short circuited before wiring removal.

9.  PHASE SEQUENCE : Ensure that the input voltage and current correspond with each other, have consistent phase sequence, and are in the same direction.

10.  WIRING MODES : Supports both three phase three wire and three phase four wire configurations; set the mode in the meter to match actual wiring.

TERMINAL LAYOUT
