5.1 Start-up and Test
AC Line Operation
1. Before making any power supply connections, verify the correct voltage, polarity, and
frequency are available from both the AC utility power source and the DC battery system.
2. Verify the AC circuit breaker (located on customer supplied service disconnect) and the
battery breaker on the VMX Power Supply are off.
3. Plug the VMX Power Supply power cord into the enclosure convenience outlet, and the
battery cable into the Battery Input connector on the front of the power supply. Plug the
RTS into the Temp Probe connection and attach it to the side of the center battery. If
applicable, connect the LRI wiring to the LRI ± terminals and the auxiliary output wires to
the AUX ± terminals on the terminal block.
4. Switch the AC (service disconnect) circuit breaker on to start initial power up. During
this stage the power supply performs a “display self-test”, and verifi es the confi guration
for the power supply. The confi guration screen looks similar to the fi gure below. After
the initial display self-test, a No Batteries alarm message appears in the Smart Display
because the battery breaker is still off. The green output LED remains off, and the red
alarm LED continues to fl ash until the battery breaker is switched ON and the power
supply qualifi es the batteries (this may take up to one minute).
5. Switch on the battery breaker. Within one minute the fl ashing red alarm LED turns OFF,
the green output LED turns ON, the No Battery alarm clears, and the power supply
resumes normal operation. Use the Smart Display to verify operations and Setup as
needed.
