Uninterruptible Power Supply

An optional UPS (Uninterruptible Power Supply) may be used for power holdover. The type of UPS depends on the holdover requirements. Holdover times vary from less than 10 minutes to up to 8 hours. The UPS must provide surge protection for all connected cabinets.

1.Connect the UPS to an electrical outlet capable of handling the power requirements of all cabinets:

a.For 100 VAC, multiply 4.5 amps times the number of cabinets.

b.For 120 VAC, multiply 3.8 amps times the number of cabinets.

c.For 200 VAC, multiply 2.3 amps times the number of cabinets.

d.For 220-240 VAC, multiply 2.0 amps times the number of cabinets.

2.Be sure that Cabinet A (control carrier) is connected to an “unswitched” or “always on” electrical outlet on the UPS.
