> Battery installation or replacement only allowed in an
Ex‑free zone.
> Ensure that the self‑adhesive insulating foil is placed
properly between housing and battery contacts.
Insert (replace) battery
Required tool Allen key, size 2.
1. Use a Phillips screwdriver to unscrew the screw of the battery
compartment lid.
2. Remove battery compartment lid with captive screw.
When changing the battery, please remove the discharged
battery.
IMPORTANT! Tools for battery replacement must not cause
a short‑circuit.
3. Put in the new battery in correct position (compare to gure
inside the housing).
IMPORTANT! Please ensure that the insulating foil
