Installation/configuration notes
Battery Considerations
The power supply accommodates up to two 12 VDC, 7 Ah standby batteries and automatically switches to battery power if AC input power fails. When batteries are not used, a loss of AC power results in a loss of output voltage. When batteries are used, they must be lead acid or gel type.
uFour fuse-protected, Class 2 Rated, power limited outputs
u12 VDC or 24 VDC selectable output
uOutputs are filtered and electronically regulated
uMain power input fuse rated at 3.5 A, 250 V
uShort circuit and thermal overload protection
Mounting Considerations
Mount indoors in areas protected from rain or moisture.
Wiring Considerations
Use 14 AWG (ISO 2.5 mm2) or larger wiring for all power connections (battery, DC output, AC input). Use 22 AWG to 18 AWG (ISO 0.34 mm2 to 0.75 mm2) wiring for power limited connections (AC fail, low battery reporting).
Notice
Maintain a minimum of 0.25 inch (0.64 cm) spacing between power limited wiring and wiring that is not power limited (AC input, battery wires).
