To reduce the risk of electric shock, disconnect the UPS from the main supply before installing a computer inter-
face 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 re-
quired precautions. Keep unauthorized personnel away from batteries.
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 be-
cause 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.
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.
