4.6 Testing the UPS
Before turning off the AC power to the intersection as a final test, verify proper
installation and ability to go ON BATTERY by placing the MANUAL BYPASS SWITCH
to BYPASS. The unit should immediately go ON BATTERY. When the MANUAL

immediately restore the AC power for the intersection at the upstream circuit breaker.
