APPENDIX A: ELECTRICAL WIRING CHECKLIST
Complete this checklist to ensure that the Symmetra RM has been wired properly.
Ensure that all switches (system enable, maintenance bypass, input circuit breaker, and
bypass circuit breaker) are in the Off or Stand By position. Turn off or unplug all
equipment connected to the Symmetra RM.
Ensure that the input voltage selection switch is in the appropriate position.
1. Apply power to the system input. Measure the voltage at the input terminal block. Record the measured
voltages:
L1-L2 for 200/208 Vac __________________________________________
OR
L1-Neutral for 220/230/240 Vac: __________________________________
The measured voltage must be between 184 and 265 V. If it is not, do not continue! Verify
the wiring from the power source to the input wiring connections. Repeat step 1.
2. Connect the PowerView display bezel.
3. Switch the input circuit breaker, then switch the system enable switch on.
The system will make some clicking sounds as it powers up, and may display fault messages on the
PowerView display. Disregard the messages at this time.
4. Press the escape key on the display until the top level menu screen appears. Select “Status.” Pressing the
enter key opens the voltage status screen, shown below.
