3. Safety information
Since the UPS unit operates on line power and contains a bank of high-current backup
batteries, the information in this chapter is important to all personnel involved.
Storage and transportation
Because of the high energy stored within the batteries, the UPS equipment must be
handled with care. The UPS must always be kept in the position marked on the package
and must not be dropped.
Installation
Do not operate the equipment in the presence of flammable gases or fumes. Operation of
any electrical equipment in such an environment constitutes a safety hazard. Do not place
the UPS in an airtight room.
The UPS system must be installed according to the instructions in this manual. Installation
may be performed by qualified personnel only. Failure to recognise the electrical hazards
could prove fatal.
WARNING!
Do not open the UPS cabinet! Some components inside the UPS cabinet carry
high voltages. To touch them may prove fatal. All operations inside the unit must
be carried out only by service personnel from the manufacturer or from an agent
authorised by the manufacturer.
User operations
The only user operations permitted are:
Starting up and shutting down the UPS unit (not the initial start up).
Using the maintenance bypass switch of the parallel module
Operating the user interface.
Connecting data interface cables.
Monitoring the UPS with LanSafe III and FailSafe III software.
These operations must be performed according to the instructions in this manual. During
any of these operations, the user must take greatest care, and perform only the prescribed
operations. Any deviation from the instructions could be dangerous to the operator.
