Equipment is to be installed and serviced by authorized / trained
personnel only. Installation should conform to all local codes and in accordance
with the National Electrical Code. Shut branch circuit power before installing /
servicing equipment. Product is intended for indoor use only.
4. Installation Instructions:
1. Unpack product. Do not discard packaging material until installation is complete.
2. Pre-drill holes on the wall where enclosure is to be mounted. Choose a vertical surface (wall)
strong enough to support the full weight of the assembly. Select a mounting location in an area
without excessive moisture; for indoor installation only and in a secured area (Electrical Room).
3. Secure enclosure to the desired wall location with the
appropriate sized fasteners using the four mounting
holes in the cabinet.
4. Disconnect power to the branch circuit to which the
product will be connected.
5. Connect incoming AC power (120 V, 60 Hz):
–Hot (L1) (black) to terminal marked “L”.
–Neutral (L2) (white) to terminal marked “N”.
–Ground (Green) to terminal marked “G”.
6. Use the knockout in bottom of cabinet for 120 VAC
wiring. Route the 120VAC wiring at least 1/4" from (low
voltage) wiring.
7. Keep a 1/4" (0.635 cm) separation between power-
limited wiring and on-power-limited wiring. Use separate
knockouts for power limited wiring.
8. Connect external loads to appropriate terminals shown in
Fig 1: Connect circuit #1 to terminals marked “VO1+” and
“VO1–”. Connect circuit #2 to terminals marked “VO2+”
and “VO2–”. Continue to connect the remaining circuits,
carefully observing polarity.
9. Power the branch circuit and observe red output LEDs
illuminated. Illuminated LEDs 1-4 or 1-8 mean that Dc
power is present on outputs.
10. To avoid potential damage, verify that output voltage and load current does not exceed output
limitations. (A single extinguished LED can mean an overload condition) See troubleshooting
guide for more information.
11. For Battery backup: If battery backup is required, use the provided battery leads and connect
the Lead Acid battery(s) 7AH 12V to the battery charger terminals while carefully observing
polarity. Set the output voltage on the trim pot shown in Fig. 1 to 13.8VDC for proper charging.
Battery(s) not supplied with power supply unit. We suggest using Power Sonic Battery part NO.
PS1270, UL File NO.MH20845 or any Recognized Lead Acid UL Battery of same capacity and
type,7AH 12V.
