Do not install or operate the control unit or any supplementary components in
areas at risk of explosion (CAN BE FATAL)!
The control units can be mounted right on the wall, on a mounting frame or on
a stand.
The standard cable supplied is 5 m long. This ensures that the control unit will
be positioned close to the photometer.
