Introduction
This manual provides information for removing and installing transformers T1 and T3.
The procedures in this manual are provided to facilitate shipping the system when
weight restrictions, at the receiving facility, prevent shipping the system with T1 and T3
assembled in the system cabinets.
The UPS system is housed in a free-standing cabinet, divided into three sections to
facilitate shipping. The cabinet sections line up and match in style and color, and have
safety shields behind the doors for hazardous voltage protection. The following
illustration depicts a typical Powerware 9315 (500 kVA---750 kVA) UPS System.

Safety Considerations
The UPS cabinet is designed for industrial or computer room applications, and contain
safety shields behind the doors. However, the UPS system is a sophisticated power
system and should be handled with appropriate care, following these guidelines:
·Keep surroundings clean and free from excess moisture.
·Do not operate the UPS system close to gas or electric heat sources.
·The system is not intended for outdoor use.
·The operating environment should be maintained within the parameters
stated in this manual.
·Keep the cabinet doors closed and locked to ensure proper cooling airflow
and to protect personnel from dangerous voltages inside the unit.
·The UPS system contains its own power source. Lethal voltages are
present even when the UPS is disconnected from utility power.
WARNING:
Only AUTHORIZED SERVICE PERSONNEL should perform maintenance on or
service the UPS system.
If service or routine maintenance is required:
·Ensure all power is disconnected before performing installation or service.
·Ensure the area around the UPS system is clean and uncluttered.
·Battery maintenance or battery replacement should be performed only by
authorized service personnel.
·Observe all DANGER, CAUTION, and WARNING notices affixed to the
inside and outside of the equipment.

2.1.3 Removing T1
To remove T1, perform the following procedure:
CAUTION:
Lift only with forklift or transformer damage may occur.
NOTE: In steps 1and 10, gain access to the transformer mounting hardware inside
the cabinet base through the cooling air cutouts in the cabinet base.
1. Remove eight transformer mounting bolts, nuts, and washers securing
transformer to cabinet base (see figure 2---5). Retain hardware.
2. Position the transformer power cables, so that the cables will not interfere with
the removal of the transformer from the cabinet.
3. Adjust forks on fork lift to correspond to the spacing between the transformer
mounting rails.
4. Slowly move fork lift into position under transformer.
5. Carefully lift transformer just enough to clear cabinet base. Ensure top of
transformer does not come in contact with the horizontal cabinet brace.
NOTE: In step 6, hold side transformer baffles (see figure 2 ---2) away from
transformer while removing transformer.
6. Move forklift backward, removing transformer from cabinet.
CAUTION:
In step 7, ensure that no hardware falls into the transformer. As a
precaution, cover the top of the transformer windings with a cloth or
cardboard. Any hardware falling into the transformer must be
removed.
7. Connect jumper wires to transformer lugs using the information contained in
table 2---1. Mount one wire to front of lug and one to back of lug, using two flat
washers (one on back and one on front of bolt), one belleville washer, and one
nut. Tighten bolts securely. See figure 2---5 for terminal lug locations.
