IMPORTANT! To ensure safe and reliable operation, ACA5-20PC
ammeters must be installed and serviced by qualifi ed technical per-
sonnel. Contact Murata Power Solutions if there is any doubt regarding
ammeter installation and/or operation.
Measurement Type: ACA5-20PC ac ammeters employ a full-wave-
rectifi ed, average responding, rms-calibrated circuit to measure the
stepped-down output of their built-in L1 current transformer (CT) .
Stated accuracy specifi cations are measured using a sine-wave cur-
rent at or close to the full-scale input level, at nominal line frequency.
Calibration: Periodic recalibration of ACA5-20PC ammeters is not
required under normal, indoor operating environments. If user calibra-
tion is necessary, it should be performed by qualifi ed technical personnel.
Calibration is performed with potentially lethal voltages applied to the
ACA5-20PC and its associated wiring, with the specifi ed full-scale
current fl owing through the ammeter’s built-in current transformer.
A plastic, fully-insulated adjusting tool must be used to access the
recessed 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 ACA5-20PC ammeters.
Wire Gauges and Fusing: Wires specifi ed in the Functional Specifi ca-
tions section must be used for making connections to ACA5-20PC
Series ammeters. All power-supply and load wiring must be rated for
the supply voltages and currents they will conduct and must comply
with any code or application-mandated requirements pertaining to the
user’s specifi c installation.
