What It Means
The output voltage is too high or too low (out
of tolerance). If the alarm was caused by high
output voltage, the unit transfers to static
bypass operation if bypass is within
tolerance. If bypass is not within tolerance,
the unit transfers to standby and does not
supply output voltage.
If the alarm was caused by low output
voltage, the unit transfers to static bypass
operation if bypass is within tolerance. If
bypass is not within tolerance, the unit
transfers to battery for five seconds and then
transfers to standby and stops supplying
output voltage.
The unit is loaded with more than nominal
load on one or more phases. The UPS status
does not change until it cannot maintain the
correct output voltage. Then, the unit
transfers to static bypass operation if bypass
is within tolerance. If not, the unit transfers to
battery for five seconds; then, it transfers to
standby and stops supplying output voltage.
The temperature on the heatsink for the mains
static switch is higher than the shut down
level, and the mains static switch has opened.
The unit switches to battery operation. When
the temperature falls below the shutdown
level, the unit transfers back to normal
operation. If the temperature does not fall to
this level before the Low DC Shutdown, there
will be no output to the load equipment.
The temperature on the heatsink for the mains
static switch is higher than the warning
setpoint. The unit's status does not change.
However, if the temperature continues to rise,
the unit will sound a "Static switch 1 temp.
shutdown" alarm.
If the UPS is in standby, restart the UPS
by pressing the green button inside the
door. If the UPS will not restart, a user
may have started an emergency power off
(EPO) shutdown. Find out if the EPO
shut down the UPS; if it did, find out
why and make sure the emergency has
passed. Then, you can reset the EPO and
restart the unit by pressing the green
button inside the door. If the unit still will
not restart, call BEST's Worldwide
Service.
Shut down equipment connected to the
UPS until the load is below 100%. An
electrician must connect these loads to
another power source. If the alarm
persists, call BEST's Worldwide Service.
Find the vents for the UPS fans and check
to see if the fans are operating. Do not
try to open the unit, and do not insert
anything into a fan vent. If the fans are
not operating, call BEST's Worldwide
Service.
If the fans are operating, make sure the
room temperature is below 80
F
(27
C). If not, cool the room. If the room
was below this temperature, call BEST's
Worldwide Service.
