SERVICE

If any problems are observed with your MINUTEMAN AT Series UPS, contact your supplier or
Para Systems, Inc. Customer Service Department.  Prior to calling for service, please write down
and be prepared to discuss all unit light and audible indications in each mode (AC and Inverter)
and whether or not the unit supplies power in either mode.  Below is a guide to assist you in
locating some common problems.

Do not remove the unit cover or attempt to service this unit.  There are no user serviceable
components inside.  Unauthorized service will void the warranty.

COMMON UPS PROBLEMS

  No normal AC mode function.  "AC Fault", "AC Fail" and "Fuse/Breaker Fault"

LEDs will provide an indication of the power problem.

1.  No power available at commercial receptacle.

2.  Commercial voltage is too low or too high.  Report this problem to your

local utility company.

Acceptable ranges are:

120VAC units -- 110VAC to 130VAC
208/220/230/240VAC units -- 200VAC to 250VAC

3.  AC fuse blown (AT650, AT800 or AT2300) or AC breaker tripped

(AT1200 or AT1600).  Replace fuse if it is blown.

CAUTION:  Turn off the MINUTEMAN power switch and disconnect the
power plug from the commercial receptacle before removing the AC fuse
from the holder.  Inspect the fuse carefully, since it is sometimes difficult
