Maintenance
Charging the rechargeable batteries
Even if the device is not used, we recommend that you store the device in the charger
(Charging module X-am 1/2/5000, order no. 83 18 639)!
To maintain the lifetime of the batteries, charging is temperature controlled and only
performed in a temperature range of 5 to 35 °C.
When this temperature range is left, the charging process is automatically interrupted
and automatically continued after the temperature range has been reached again.
The charging time is typically 4 hours.
A new NiMH power pack reaches its full capacity after three complete charging/
discharging cycles. Never store the device for extended periods without being
connected to a power source (maximum of 2 months) because the internal buffer
battery will drain.
Charging with the multiple charging station
A maximum of 20 devices can be charged at the same time on the power pack (order
no. 83 18 805) of the multiple charging station.
When attaching the charging modules, disconnect the power pack from the mains
supply!
Attaching charging modules
1 Turn the slots of the interlock into a horizontal position by using a screwdriver or
coin.
2 Insert the projecting tongue of the charging module (at the same time, current entry)
until it engages.
1 Close the interlock with a quarter turn (slot is positioned vertically).
WARNING
Explosion hazard! To reduce the risk of flammable or explosive atmospheres igniting,
it is essential that the warning notices below are observed:
Do not charge underground or in explosion-hazard areas! Danger of explosion!
The chargers are not designed in accordance with the regulations for firedamp and
explosion protection.
Charge the NiMH power pack T4 (HBT 0000 type) or T4 HC (HBT 0100 type) using
the corresponding Dräger charger. Ambient temperature during the charging process:
0 to +40 °C.
