IMPORTANT! To ensure safe and reliable operation, ACA5-20RM
ammeters must be installed and serviced by qualifi ed technical
personnel. Contact Murata Power Solutions if there is any doubt
regarding ammeter installation and/or operation.

current at, or close to, the full-scale input range, at nominal line
frequency of 60Hz.

calibration is necessary, it should be performed by qualifi ed technical
personnel. Calibration is performed with potentially lethal voltages
applied to the ACA5-20RM and its associated wiring, with 5.0 amps
fl owing through the ammeter’s built-in toroid sensor. A plastic,
fully-insulated adjusting tool must be used to access the calibration
potentiometer located on the back of the meter (see Mechanical
Specifi cations). Contact MPS if additional information is required
regarding calibration, setup, or any other technical issue pertaining to
ACA5-20RM ammeters.
