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.
