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

PowerwareÒ 9315 Installation, PowerwareÒ 9315 Operation, and the PowerwareÒ Series 685 and 1085 Auxiliary Battery Cabinets Installation manuals provided with the UPS system and battery cabinet accessory.

The parallel cabinet is a free-standing cabinet. Figure 1 shows a typical parallel cabinet.

Getting Started

This section describes how to install the parallel cabinet. It contains only instructions for installing the parallel cabinet as a remote cabinet,

configuration needed for parallel redundant operation, and basic site preparation procedures. Figure 2 shows the front and side view of the parallel cabinet.

Figure 2. Front and Side View of Parallel Cabinet

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 PowerwareR 9315 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 PowerwareÒ 9315 Operation manual provided with the UPS system. The operating environment must meet the size and weight requirements supplied in the PowerwareÒ 9315 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---	40˚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.

8	Powerware 9315 Parallel Redundant System I & O
	164202013, Rev. D 041599

Environment Considerations

The life of the parallel redundant system will be adversely affected if the installation 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. If wire is run in an ambient 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 PowerwareÒ 9315 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.

OUTER

PACKAGING

FOAM CUSHION

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.

10	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.
