The device may only be operated in a hori-
zontal position.
The air surrounding the charger must be kept free from battery acid vapour as far as pos-
sible. You should therefore avoid mounting the device directly above the battery that is to 
be charged.
Cooling air
The charger must be set up in such a way that the cooling air can flow unimpeded through 
the vents in the housing that are provided for that purpose. Ensure that there is always a 
minimum clearance of 20 cm (7.87 in.) around the air inlets and outlets. The surrounding 
air must be free from
- Excessive dust
- Electrically conductive particles (carbon black or swarf)
- Heat sources
Cooling air is drawn in and flows out as indicated by the arrows in the following illustrations.
NOTE!
Danger due to partially or fully covered air inlets and outlets.
This can result in damage to property.
► If several chargers are set up one behind the other, they should be offset.
If the chargers are arranged in a line one behind the other without being offset, the space 
between the chargers must be as follows: 
- Minimum distance 20 cm (7.87 in)
20 cm (7.87 in.)
