Charging The Rechargeable Batteries; Charging With The Multiple Charging Station - Dräger X-AM 5000 Technical Manual

Maintenance
After replacing the power pack T4, it is recommended that a complete charging is car-
ried out.
After the batteries have been replaced:
−
The settings and data are stored when the battery is replaced. The sensors warm
up again.

Charging the rechargeable batteries

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.
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 connec-
ted 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).
