PANEL INSTALLATION
All connections to ACA-20RM Series ammeters must be made after
the ammeter is securely attached to the panel and with all associated
load and supply voltages de-energized (off), using extreme caution and
observing all safety measures applicable to the user’s installation.
Care should be exercised when passing conductors through the amme-
ter’s built-in toroid sensor L1. The installed wire-positions should be such
that minimal mechanical forces are applied to L1, TB1, or to the ammeter
itself. In high-vibration environments, it is strongly recommended that
adequate strain reliefs be used for all wiring.
Using Figure 3 as a guide, carefully insert the bezel/color fi 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 ACA5-20RM
pc-board assembly as shown and then attach and securely tighten all
four hex nuts. Use only the factory-supplied hardware as the use of sub-
stitute hardware could result in an unsafe installation and/or adversely
affect the reliability of the ammeter.
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 or modifi cations.
