• Refer to national and local electrical codes for acceptable external wiring practices.
• To allow for future kVA upgrades, consider installing a derated UPS using wiring and external overcurrent
protection breakers sized for a fully rated UPS.
• For external wiring, use 90°C copper wire. Wire sizes listed inTable 3-5 are for copper wiring only. If wire is
run in an ambient temperature greater than 30°C, higher temperature wire and/or larger size wire may be
necessary. Wire sizes are based on using the specified breakers.
• Material and labour for external wiring requirements are to be supplied by designated personnel.
• If installing an external maintenance bypass, all feeds to the UPS including the Rectifier Input Breaker (RIB) (if
installed) must have a service disconnect independent of the maintenance bypass power path. Most
maintenance bypass solutions provide UPS input feeds derived from but isolated from the maintenance
bypass power path. If the maintenance bypass solution being installed does not provide such functionality,
DO NOT use a single feeder breaker to supply both the UPS and the maintenance bypass.
• The bypass feed into this equipment uses four wires (three line conductors and neutral conductor), plus
grounding conductor (protective earthing conductor) .The rectifier feed into this equipment uses four wires
(three line conductors and neutral conductor), plus grounding conductor (protective earthing conductor).The
phases must be symmetrical about ground (from a Wye/Star source) for proper equipment operation.
• Parallel UPS input wiring size requirements and output wiring size requirements from the UPSs to the Tie
Cabinet are the sames as those for single systems.
• This device is not equipped with its own mains separation device. It is , therefore, essential that the customer
install such a device at the installation site near the UPS.
• Install a proper three-pole overcurrent disconnect device before connecting to the UPS, the disconnect
device shall disconnect simultaneously all line conductors of the AC MAINS SUPPLY.
• Do not disconnect neutral, neutral required for system operation.
• If a disconnect device interrupts the neutral conductor, it shall simultaneously interrupt all line conductors.
• When single-phase current exceeds 100A, switches of protective atmosphere should be equipped with
arc-control device.
• The UPS requires an input neutral connection. Ensure that an input neutral is connected prior to energising
the UPS. If a 4 pole AutomaticTransfer Switch is installed upstream of the UPS it must work with a break
before make transition with a minimum transfer time of 50ms.

The line-to-line unbalanced output capability of the UPS is limited only by the full load per phase current values
for AC output to critical load shown inTable 3-5.The recommended line-to-line load unbalance is 50% or less.
Readily accessible disconnect devices (Bypass and output overcurrent protection and bypass and output
disconnect switches) are to be supplied by the customer.Table 3-8 lists the recommended rating for bypass
and output circuit breakers.
There is no DC disconnect device within the UPS. A battery disconnect switch is recommended, And may be
required by local codes when batteries are remotely located. The battery disconnect switch should be installed
between the battery and the UPS
External DC input overcurrent protection and disconnect switch for the remote battery location is to be
provided by the user.Table 3-9 lists the maximum rating for continuous-duty rated circuit breakers satisfying the
criteria for both.
Battery voltage is computed at 2 volts per cell. Rated battery current is computed at 2 volts per cell.The battery
wiring used between the battery and the UPS should not allow a voltage drop of more than 1% of nominal DC
voltage at rated battery current. If the conductors used for DC input from the battery cabinets to the UPS are
those provided by the UPS manufacturer, and the UPS and battery cabinets are manufactured by the same
supplier, then it is acceptable if they do not meet the noted minimum conductor sizes.

3.2.3 UPS System Interface Wiring Preparation
Control wiring for features and options should be connected at the customer interface terminal blocks located
inside the UPS.
WARNING
Do not directly connect contactor contacts to the mains related circuits. Reinforced insulation is
required before connecting to the mains.
Read and understand the following notes while planning and performing the installation:
• Interface wiring should be rated for 24V, 1A minimum.
• For interface wiring from 30V to 600V, the wire should be rated for 600V, 1A minimum.
• Because of the REPO and building alarm wiring route in the UPS cabinet, the wire should be rated for a
minimum of 300V.
• Use twisted-pair wires for each input and return or common.
• All interface wiring and conduit is to be supplied by the customer.
• When installing external interface wiring between a REPO or building alarm and the UPS interface terminals,
conduit must be installed between each device and the UPS cabinet.
• If using the power terminal wiring channel, keep interface wiring separate from power wiring or use shielded
wire.
• If using conduit, install the interface wiring in separate conduit from the power wiring.
• All building alarm inputs require an isolated normally-open contact or switch (rated at 24 Vdc, 20 mA
minimum) connected between the alarm input and common terminal. All control wiring and switch contacts
are customer-supplied.
• LAN and telephone drops for use with Mini-Slot connectivity cards must be supplied by the customer.
• The REPO feature opens all contactors in the UPS cabinet and isolates power from your critical load. Local
electrical codes may also require tripping upstream protective devices to the UPS.
• The REPO switch must be a latching-type switch not tied to any other circuits.
• A jumper wire must be connected between pins 3 and 4 on the REPO terminal block if using a normally-
closed REPO switch.
• REPO wiring should be a minimum of 0.5~2.0 mm2.
• The REPO switch wiring must be in accordance with local regulations.
• The maximum distance between the REPO and the UPS cannot exceed 150 metres (500 feet).

3.3 Inspecting and Unpacking the UPS Cabinets
WARNING
The UPS cabinet is heavy (seeTable 3-1). If unpacking and unloading instructions are not closely
followed, the cabinet may tip and cause serious injury.
The cabinet is shipped bolted to a wooden pallet and protected with an outer wood container.
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 an
Eaton service representative immediately.
For the following step, verify that the forklift or pallet jack is rated to handle the weight of
the cabinet (see Table 3-1 for cabinet weight).
NOTE
2. Use a forklift or pallet jack to move the packaged cabinet to the installation site, or as close as possible,
before unpacking. If possible, move the cabinets using the pallet. Insert the forklift or pallet jack forks
between the supports on the bottom of the pallet (see Figure 3-3 for the UPS cabinet centre of gravity
measurements).
CAUTION
Do not tilt the UPS cabinets more than 10° from vertical or the cabinets may tip over.
3. Set the pallet on a firm, level surface, allowing a minimum clearance of 3m (10 ft) on each side for
removing the cabinet from the pallet.
4. Remove the protective wood container from the cabinet:
For the following steps, use pincer type pliers or a large flat blade screw driver to
straighten the securing tabs.
NOTE
a. Straighten the tabs securing the top panel of the wooden container to the side panels of the
container.
b. Remove the top panel and retain for later use as a ramp in unloading the cabinet from the pallet.
c. Straighten the tabs securing the side panels of the container to the front and back panels of the
container.
d. Remove the side panels.
e. Straighten the tabs securing the front and back panels of the container to the bottom of the container.
f. Remove the front and back panels.
5. Remove the inner protective packaging. Retain the parts kit box, ramp brackets, and ramp extension
packed at the top of the cabinet.
6. Recycle the remainder of the outer shipping container and the inner protective packaging in a responsible
manner.
