7. Installation and set-up / operation

After mounting, wiring and setting check the safe functioning of the unit
In the case of wire break or short circuit of the sensor cable the relay "wire moni-
toring" is de-energised and the red LED lights. After rectification of the fault the con-
trol monitor is again ready for operation

8. Maintenance, repair, disposal

If used correctly no maintenance and repair measures are required.
