2.1APP SPS Installation and Power Module Removal
Procedure
1. Locate Service Power Inserter (SPI) in enclosure. (Refer to Figures 2-1
and 2-2.) For 20A SPI, plug APP SPS "Jones" connector into SPI. (Figure
2-1.) For 25A SPI (9022S model only), plug APP SPS into red and white
25A connectors. (Figure 2-2.)
2 Determine the line voltage of the UPS.
3. For APP 9015S model only:
Select appropriate line voltage (120/240 VAC) by using the Input Voltage
Selector switch.
4. Select and connect appropriate line cord to Input Connector and plug into
outlet.
CAUTION: Do not use the 120 VAC cord to plug into GFCI outlet!
The GFCI outlet is intended for lights and tools only.
If necessary, remove the LAP and use that outlet.
5. Set the 60/75/90 VAC selector switch to the desired voltage. Plug the
APP SPS power cord into the enclosure's convenience outlet. (See
Figures 2-3 and 2-4.) Switch the APP SPS ON, and verify that the
output power indicator is lit.
6. Toggle the SPI's ALT/ON switch to ALT. This transfers output power from
the module to the APP SPS which can now be used to maintain regulated,
non-standby power to the cable plant until a replacement power module
has been installed.
7. Switch the battery breaker on the power module OFF.
8. Unplug the power module LINE cord from the enclosure convenience
outlet.
9. Wait approximately 1 minute for the power module capacitors to fully
discharge.
10. Disconnect the wires from the power module.
CAUTION: Do not let exposed battery cables come in contact with
the chassis or enclosure.
11. Reverse this procedure when reinstalling a module.
CAUTION: The ferroresonant transformer generates heat and may
cause burns if handled with bare hands.
NOTE: Always test the power module for proper operation before
toggling the SPI's "ALT/ON" switch back to the ON position.
