personnel and power must be first switched off.

capacity, 250Vac). Please see Chapter 8.
Replacement of the lithium battery
Lithium battery replacement should only be performed by qualified personnel
and with an identical battery (see Chapter 8 for the list of spare parts). The
controller must be first switched off. Power on the controller once the battery
