To reduce the risk of electric shock, disconnect the UPS from the main supply before installing a
computer interface signal cable. Reconnect the power cord only after signaling interconnections have
been made.
Servicing of batteries should be performed or supervised by personnel with knowledge of batteries and
the required precautions. Keep unauthorized personnel away from batteries.
These UPS units are extremely heavy. Do not install the UPS in a rack or enclosure by its front two ears
only. Adjustable rack rails are required for this type of installation.
The instructions contained within this safety manual are deemed important and should be closely
followed at all times during installation and follow-up maintenance of the UPS and batteries.
CAUTION
The unit has a dangerous amount of voltage. If the UPS indicator is on, the unit’s outlets may have a
dangerous amount of voltage even when not plugged into the wall outlet because the battery may
continue to supply power.
Care should be taken to undertake installation indoors, free from electrically-conductive particles
which are under temperature and humidity control, in order to reduce the risk of electric shock.
It is best to disconnect the device using the power supply cord. Ensure that the equipment is placed in
a position near the outlet where easily accessible.
Except for replacing the batteries, all servicing on this equipment must be carried out by qualified
service personnel.
Before conducting any maintenance, repair, or shipment, first ensure that everything is turned off
completely and disconnected.
For additional safety instructions, please use the Safety Manual as a reference.
