3 Description

3.1 Product 

overview

The Dräger PSS AirBoss 5-Way Desktop Charger (Fig. 1) comprises the 
charger and a universal power supply. Up to five power packs are 
charged in the five slots on the charger.

Fig. 1

3.2 Intended 

use

The desktop charger is used to charge or health check compatible Dräger 
6 V rechargeable nickel-metal hydride (NiMH) power packs.

3.3  Universal power supply

The universal power supply transforms mains voltage to the low dc input 
required by the charger. The power supply output is 12 Vdc on a 2.1 mm 
jack plug. A green LED on the body of the power supply illuminates to 
indicate that mains power is on.

3.4 Charger

The charger takes approximately 4 to 6 hours to charge a fully 
discharged power pack. Charging stops automatically when the power 
pack is fully charged.

The health check function (

) is recommended for rechargeable power 

packs every six months. The health check takes approximately 12 to 
24 hours. At the end of the health check, the power pack is recalibrated to 
ensure the accuracy of the charge level indications. Five buttons on the 
charger start the health check for the corresponding slots.

3.5 Charger 

LEDs

A panel of colour LEDs on the charger indicates the power pack status. 
The LED display indicates the following:

3.5.1 Charging status indication

3.5.2  Health check status indication

3.6 Approvals

The European standards, guidelines, and directives according to which 
this product is approved are specified in the declaration of conformity 
(see the declaration of conformity or 

 

www.draeger.com/product-

Refer to the relevant authority for explanation of approval body symbols 
and marking on the product.

4 Use

WARNING

Explosion, fire or chemical hazard.

The charger is not approved to intrinsic safety standards. Do not 
attempt to charge a power pack underground or in an area 
designated as, or subject to, an explosion hazard.

Do not expose the power packs to heat sources, and do not short out 
the power pack terminals.

WARNING

Risk of electrical shock or equipment damage.

Only charge compatible Dräger 6 V rechargeable NiMH power packs 
using the charger.

Do not operate the charger in wet or damp conditions.

Do not allow metal objects to enter the slots of the charger.

When new rechargeable power packs are supplied they are not fully 

charged. Charge new power packs before use.
The temperature of the battery is measured by an internal thermistor. To 
protect the battery, the fast charging process is suspended if the 
temperature is below 10 °C or above 45 °C. The recommended ambient 
temperature during charging is 15 °C to 25 °C.
Power packs can remain connected to the charger without damage when 
the charging procedure is complete. However, disconnecting from the 
charger is recommended if the power pack is not used for long periods.
In the event of a power failure, power packs in the charger will be 
protected from discharging.

1. Visually inspect the charger and power supply for signs of damage or 

corrosion. If electrical contacts are dirty or corroded, clean them 
before use (see section 5.1).

WARNING

Risk of electrical shock or equipment damage.

Do not charge power packs if the charger or power supply is 
damaged.

Make sure the power supply cables cannot be crushed or damaged 
and do not present a trip hazard.

Keep the charger and power supply clear of hot surfaces and flames.

2. Place the charger flat on a clean surface, ensuring sufficient space 

and ventilation.

3. Connect the charger to an appropriate power supply.

4. Insert the power pack into an available slot, as indicated by a steady 

green LED (see section 3.5.1).

5. See the following sections on power pack charging or health checks.

4.1  Power pack charging

– Charging commences automatically (do not press the health check 

button (

) unless a health check is required).

– The charger LEDs indicate the charge status (see section 3.5.1).

4.2  Power pack health check

If the health check is started unintentionally, remove the power pack 

from the charger and wait until the LEDs extinguish. Normal charging will 
commence when the power pack is reinserted.
Repeating the health check may improve the battery capacity, particularly 
for power packs that have been unused for a long period.

The health check takes approximately 12 to 24 hours to fully discharge 
and then fully recharge the power pack. During the check, the charger 
measures the battery capacity and recalibrates the battery to ensure the 
accuracy of the charge level indications.
1. Press and hold for 3 seconds the health check button (

) next to the 

appropriate slot on the charger.

2. The charger LEDs indicate the status of the health check (see section 

3.5.2).

4.3 After 

use

1. Remove all power packs from the charger.

WARNING

Risk of electrical shock or equipment damage.

Always disconnect plugs by pulling the plug and not the cable.

2. Disconnect the power supply.

5 Maintenance

WARNING

Risk of electrical shock or equipment damage.

Do not attempt to open or disassemble the charger or power supply. 
No user repairs are permitted.

User maintenance is limited to cleaning the 5-way desktop charger when 
required.
