Introduction
The parallel redundant system allows two UPS modules to operate in parallel and
as backup for each other. When one UPS module is taken out of service for
maintenance or is not operating properly, the redundant UPS module continues to
supply uninterrupted power to the critical load. The parallel redundant system
refers to the parallel cabinet in conjunction with the UPS modules. The parallel
redundant system consists of one parallel cabinet, two identical UPS cabinets, and
up to four battery cabinets per UPS. Each UPS module may have its own battery
cabinet(s), or may share the same battery cabinet(s) with the other UPS module.
NOTE: The installation procedures of this manual only refer to the parallel cabinet
and its connection to the UPS cabinets for parallel redundant operation. The
operation section of this manual refers to the operation for the parallel
cabinet and the UPS system when in parallel. For full installation and
operation of the UPS system and battery installation, refer to the
PowerwareÒ9315 Installation,PowerwareÒ9315 Operation,andthe
PowerwareÒSeries 685 and 1085 Auxiliary Battery Cabinets
Installation manuals provided with the UPS system and battery cabinet
accessory.

The parallel cabinet is shipped on a separate pallet. Use a forklift or pallet jack to
move the packaged cabinet to the installation site, or as close as possible to the
site, before unloading from the pallet.
The basic sequence of the installation steps is:
1. Prepare the site for the cabinet installation.
2. Inspect, unpack, and unload the cabinet.
3. Create an installation plan for wiring the parallel cabinet to the corresponding
UPS modules.
4. Prepare for wiring.
5. Complete the installation checklist from the PowerwareR9315 Installation manual.
6. Have authorized service personnel perform preliminary checks and startup.
NOTE: Startup and operational checks should be performed only by authorized
service personnel. This service is usually offered as part of the sales
contract for your UPS system.
Preparing the Site
For the parallel redundant system to operate at peak efficiency, the installation site
should meet the environmental parameters outlined in the PowerwareÒ9315
Operation manual provided with the UPS system. The operating environment must
meet the size and weight requirements supplied in the PowerwareÒ9315
Installation manual provided with the UPS system. If the parallel redundant system
is to be operated at an altitude higher than 1500 meters (5000 feet), contact the
local sales or service office for important information about high altitude operation.
The basic environmental requirements for operation of the parallel redundant
system are:
Ambient Temperature Range: 0 --- 4 0 ˚C (32---104˚F)
Recommended Operating Range: 20---25˚C (68---77˚F)
Maximum Relative Humidity: 95%
The parallel cabinet uses convection cooling to regulate internal component
temperature. Air inlets are in the front of the cabinet, and outlets are in the top.
Clearance in front of and above each cabinet for proper air circulation is essential.

Environment Considerations
Thelifeoftheparallelredundantsystemwillbeadverselyaffectediftheinstallation
does not meet the following guidelines:
1. The parallel cabinet must be installed on a sealed concrete pad on a sealed
concrete floor.
2. The parallel cabinet must be installed in a dust-free environment.
3. The parallel cabinet must be installed in a humidity-controlled environment.
Preparing for Wiring the Parallel Redundant System
See Tables A---1 through A---4 in Appendix A of this manual for wiring requirements.
The power wiring for this equipment is rated at 75_C. Ifwireisruninanambient
temperature greater than 30_C, higher temperature and/or larger size wire may be
necessary. Wiring for the paralle cabinet should be installed through the 28.6 mm
(1.1 in.) knockout in the bottom of the UPS cabinet. The top entry connection
requires installation of 1/2-in. flexible conduit within the UPS. Bottom entry
connection requires no additional routing of conduit within the UPS. For UPS
external wiring requirements, including minimum AWG size of external wiring, see
the PowerwareÒ9315 Installation manual provided with the UPS system.
NOTE: Material and labor for external wiring are to be provided by designated
personnel.

Inspecting and Unpacking the Parallel Cabinet
The first task in preparing for installation of the parallel cabinet is inspecting and
unpacking the cabinet. The cabinet arrives covered with protective packaging
material as shown in Figure 3.
FOAM CUSHION
OUTER
PACKAGING
Figure 3. Cabinet as Shipped, with Outer Packaging and Pallet
1. Carefully inspect the outer packaging for evidence of damage during transit.
CAUTION:
Do not install a damaged cabinet. Report any damage to the carrier and
contact the local sales or service office immediately.
2. Use a forklift or other material handling equipment to move the cabinet to a
convenient unpacking area. Insert the forklift jacks between the foam cushions
on the bottom of the unit.
CAUTION:
Do not tilt cabinet more than 10 degrees from vertical.

Powerware 9315 Parallel Redundant System I & O
164202013 Rev. D 041599
3. Set the pallet on a firm, level surface, allowing a minimum clearance of
4.6m (15 ft) on each side for removing the cabinet from the pallet.
4. Cut the steel bands around the cabinet.
5. Remove the protective cardboard covering from the cabinet, cutting where
indicated, using a knife blade no longer than 25 mm (1 in.).
NOTE: Do not discard the packaging material yet. Instructions for unloading the
cabinet from the pallet are printed on the cardboard, and you will need to
refer to them.
6. Remove the plastic bag and foam packing material, and discard or recycle
them in a responsible manner.
Unloading the Parallel Cabinet From the Pallet
The parallel cabinet consists of four supports secured to foam cushions. The foam
cushions act as shock absorbers for the cabinet during shipment.
WARNING:
Cabinet is extremely heavy. If unloading instructions are not closely
followed, the cabinet may tip and cause serious injury.
Turning the jacking bolts unevenly may cause the cabinet to become
unbalanced. To prevent tipping, raise and lower the jacking bolts
evenly. The cabinet should only be raised approximately 3 mm (1/8 in.)
above the floor (just enough to remove foam cushions).
1. Remove the doors. Remove the retaining screw located inside each door at
the bottom hinge pivot point, then lift the door off. Save the retaining screws
for reinstallation of the doors.
2. Locate the field kit (packed inside of the cabinet or communication panel).
Locate the four ½-in. jacking bolts and install them in the threaded holes in the
front and rear supports. Place a floor protector underneath each jacking bolt,
and screw the bolts down against them. The floor protectors will save the floor
from being marred by the jacking bolts.
3. Loosen, but do not remove the hardware holding the foam cushions to the
front and rear supports (labeled “1” in Figure 4).
4. Turn each jacking bolt consecutively, two full turns, until the foam cushions
clear the floor by approximately 3 mm (1/8 in.).
5. After the foam cushions clear the floor, remove the hardware loosened in
step 3. Pull the foam cushions out from under the cabinet, and discard or
recycle them in a responsible manner.
