Power Xpert 9395 UPS (450–550 kVA) Installation and Operation Manual
When selecting the most appropriate grounding scheme for your application, consider items such as:
Ground fault detector settings
Site specific specifications and requirements
Local codes and regulations
S
MOBs with dual auxiliary contacts are to be provided by the customer. Table 3‐15
on page 3-16 lists the recommended rating for the MOBs.
The tie cabinet must contain Module Output Breakers (MOBs) with dual auxiliary
contacts for control of the system. Without dual auxiliary MOBs, UPMs are not
allowed to go to bypass individually during servicing. All UPMs will go to bypass
instead of just the UPM needing service, decreasing critical load protection. With
dual auxiliary MOBs, one UPM can be bypassed while the remaining UPMs
support the load as long as the remaining UPMs have the capacity to do so.
The UPS cabinet is palleted separately for shipping. The cabinet is shipped bolted to a
wooden pallet (see Figure 3‐8) and protected with outer protective packaging
material.
The UPS cabinet is heavy (see Table 3‐1 on page 3-2). If unpacking and unloading instructions are not
closely followed, the cabinet may tip and cause serious injury.
To prevent damage to the wiring channel and wiring in the UPS cabinet base when lifting or moving the
cabinet:
S
Lift and move the cabinet using only the front or rear forklift slots.
S
Verify that the forklift forks are in a horizontal position before inserting them into the forklift slots.
DO NOT angle fork tips upward.
S
Insert the forks all the way through the base. DO NOT insert forks partially into the base to move the
cabinet.
S
Forks may be partially inserted into the front or rear forklift slots for minor positioning if the forks are
kept in a horizontal position with no upward angling.
S
DO NOT use the forklift slots on the end of the cabinet to move the cabinet.
S
End forklift slots may be used for minor positioning if the forks are kept in a horizontal position with no
upward angling.
If these instructions are not followed, damage to the wiring channel and wiring will occur.
1. Carefully inspect the outer packaging for evidence of damage during transit.
Do not install a damaged cabinet. Report any damage to the carrier and contact an Eaton service
representative immediately.
NOTE For the following step, verify that the forklift or pallet jack is rated to handle the weight of the
cabinet (see Table 3‐1 on page 3-2 for cabinet weight).
