ACA-20RM Series
True-RMS-AC Ammeters with Built-in CT
PANEL INSTALLATIONS
All connections to ACA-20RM Series ammeters must be made after the
ammeter is securely attached to its panel and with all associated load
and supply voltages de-energized (off). However, using extreme caution
and observing all safety measures applicable to the user’s installation,
50A split-core CT models can be connected to energized current-carrying
load conductors, but connections to TB1 must always be made with the
ammeter’s power source off.
Care should be exercised when passing the load-carrying conductor
through the meter’s built-in CT—particularly when larger conductors are
used. The installed wire-positions should be such that minimal mechani-
cal forces are applied to the built-in CT, TB1, or to the ammeter itself. In
Using Figure 4 as a guide, carefully insert the bezel/color ?lter assembly
into the panel opening. From the rear of the panel, install the four round
plastic standoffs over the bezel’s threaded studs. Install the pc-board
assembly; then attach and securely tighten each of the four hex nuts
to 15-20 ozf-in (0.106 to 0.140 N-m). Use only the factory-supplied
hardware as the use of substitute hardware could result in an unsafe
installation and/or adversely affect the reliability of the ammeter itself.
The recommended range of panel thickness that can be used with the
supplied hardware is 0.040 inches (1.0mm) to 0.125 inches (3.2mm).
Panel thickness outside of this range will require additional user-supplied
hardware and/or modi?cations.
high-vibration environments, it is strongly recommended that adequate
strain reliefs be used for all load and supply wiring.
