User's Manual

The APDU can be installed both indoors and outdoors. It is mounted in a
environmentally protected (IP 65) lockable box, and can be mounted without any
kind of protection from bad weather conditions. However, it is not permitted to install
the APDU outdoors in bad weather conditions. If the bad weather conditions are of a
short duration, and the APDU and all other connectors that are to be connected during
the installation are protected, the installation may continue not less than one hour after
the adverse conditions have ended.
Information on environmental requirements for the APDU is found in the Reference
Manual.
