SAFETY OF PERSONS
•
RISK OF VOLTAGE BACK FEED. The system has its own power source (the battery). Isolate the UPS and check for
hazardous voltage upstream and downstream during lockout-tagout operation. Terminal blocks may be
energised even if the system is disconnected from the AC power source.
•
Dangerous voltage levels are present within the system. It should be opened exclusively by qualified service
personnel.
•
The system must be properly grounded.
•
The battery supplied with the system contains small amounts of toxic materials. To avoid accidents, the directives
listed below must be observed:
Servicing of batteries should be performed by personnel knowledgeable about batteries and the
required precautions.
When replacing batteries, replace with the same type and number of batteries or battery packs.
Do not dispose of batteries in a fire. The batteries may explode.
Batteries constitute a danger (electrical shock, burns). The short-circuit current may be very high.
•
Precautions must be taken for all handling:
Wear rubber gloves and boots.
Do not lay tools or metal parts on top of batteries.
Disconnect the charging source before connecting or disconnecting battery terminals.
Determine if battery is inadvertently grounded. If inadvertently grounded, remove source from ground.
Contact with any part of a grounded battery can result in electrical shock. The likelihood of such shock
can be
reduced if such grounds are removed during installation and maintenance (applicable to
equipment and remote battery supplies not having a grounded supply circuit).
