7.2 Safety
Take special care when working with the batteries associated with the UPS. When all the blocks are connected, the battery
string voltage can be up to 540 Vdc. This is potentially lethal. Please follow the precautions for high voltage operation. Only
qualified personnel are allowed to install and maintain the battery. To ensure safety, the external batteries are to be
installed inside a lockable cabinet or in a purpose-designed, dedicated battery room, so that they are only accessible to
qualified service personnel.
Confirm that the battery switch has been disconnected before battery maintenance.
