Introduction
Overview
The FirstLine P Mai n te nance Bypass Switch C abi net for 160 kVA, 200 kVA, 250 kVA with
480 V Input and Output is a steel cabinet that attaches to the side of the UPS cabinet,
thereby extending the cabinet, and providing the maintenance bypass function. The
cabinet has conduit attachment points at the top and the botto m for max i mu m flexibility in
wiring the source and load power connections. Please refer to Figure 1 for the outline
drawing of the cabinet.

Applicability
This equipment can be applied to UPS models FLU-160-00, FLU-200-00, and FLU-250-00.
These UPS models operate at 480 V, 60 Hz and can be wired as delta in and delta out (3
wire plus ground) or wye in and wye out (4 wire plus ground).
For installations requiring other voltages or other wiring configurations, the equipment
covered by this manual is not appropriate. Please contact Staco Energy Products
Company for recommendations regarding the proper equipment.
It is permissible to use a larger Maintenance Bypass Switch Cabinet (MBS) than is required
for the UPS, but special installation requirements must be met: the power source
connected to the MBS must include circuit protection as specified for the input in the UPS
manual and an output breaker must be provided per the UPS manual. For example, if a
250 kVA MBS is applied to a 160 kVA UPS, a 300 A breaker must be provided at the power
source and a 300 A breaker must be provided between the MBS and the load. If the MBS
rating matches the UPS rating, then the breakers that form the MBS switch arrangement
satisfy the input and output breaker requirement for the UPS.
Part Numbers
FLU-P-160-MBPS*SK for use with 160 kVA UPS
FLU-P-200-MBPS*SK for use with 200 kVA UPS
FLU-P-250-MBPS*SK for use with 250 kVA UPS

SAFETY WARNINGS
IMPORTANT SAFETY INSTRUCTIONS SAVE THESE INSTRUCTIONS
READ AND FOLLOW ALL SAFETY INSTRUCTIONS
• Do not use outdoors.
• Do not route wiring across or near hot surfaces.
• Do not install near gas or electric heaters.
• Equipment should be installed where it will not readily be subjected to tampering by
unauthorized personnel.
• The use of accessory equipment not recommended by the manufacturer may cause
an unsafe condition.
• Do not use this equipment for other than intended use.
• This equipment connects to the output of an uninterruptible power supply.
Hazardous voltages may be present even when the electrical supply to this
equipment is turned off.
• If equipped with a maintenance bypass switch, control connections between this
equipment and the ups must be present to prevent the possibility of backfeed.
• Read and follow the instructions that came with the associated UPS or emergency
lighting system before operating this equipment.
DANGER
This equipment contains lethal voltages. All repairs and service should only be performed
by authorized service personnel. There are no user serviceable parts inside this
equipment. Operation of switches and breakers require access to the cabinet interior and
should only be performed by qualified personnel exercising appropriate caution.
WARNING
This equipment connects to the output of a UPS which contains its own energy source
(batteries). The UPS output may carry live voltage even when the UPS is not connected to
an AC supply.
To reduce the risk of fire and electric shock, install this equipment in a humidity controlled,
indoor environment, free of conductive contaminants. Do not operate near water or
excessive humidity (95% maximum). If condensation is present, the equipment must be
allowed to completely dry before operation.

CAUTION
The UPS associated with this equipment contains batteries. Batteries can present a risk of
electrical shock or burn from high short circuit current. Observe proper precautions.
Servicing should only be performed by qualified service personnel knowledgeable of
batteries and the required precautions. Keep unauthorized personnel away from batt eri es .
Read, understand, and follow all instructions in the ups manual before attempting any
operations involving the battery.
