OWERING UP AND BASIC SYSTEM VERIFICATION
1. Ensure proper configuration of all jumpers and switches.
2. Apply AC power to the power supply.
3. Ensure the green AC ON and DC1 LEDs are lit. The DC2 LED may
also be lit, depending on the position of the DC2 fuse.
4. Verify DC1 output voltage with a meter.
• If set for the 12 V nominal setting, the voltage should be
approximately 12.5 VDC.
• If set for the 24 V nominal setting, the voltage should be
approximately 25 VDC.
5. Connect the battery, if required for the installation.
6. Verify that no yellow LEDs are lit on the power supply.
7. If used, activate the FAI input and verify that the red FAI LED lights
and that the DC2 output switches states. Deactivate the FAI input (and
reset the input if configured for latching) and verify that the red FAI
LED extinguishes and the DC2 output returns to normal.
8. If the battery presence jumper is enabled, remove one lead from the
battery. Verify that the yellow SYS FLT LED lights. Reconnect the
battery and the SYS FLT LED should extinguish.
CAUTION: Risk of Damage to the System and Voided
Warranty.
Do not use the power supply with a 230 VAC input unless the
input voltage selection jumper (JP1) is cut and removed.
Failure to cut and remove the jumper may cause damage to
the system and will void the warranty.
