3.2 Connecting the control unit
Risk of electric shock
• Before working on the control unit, switch off the mains voltage, check that it is
not live and ensure that it cannot be inadvertently switched back on.
Thecontrolunitmayonlybeconnectedtothepowersupplybyaqualiedelectrician
(accordingtothedenitiongiveninBGVA3,§2paragraph3;appliesonlyinGermany).
Alwaysconnectthecontrolunitoff-circuit.
Onlyconnectthecontrolunittothemainsoveranall-poleisolationdevice.Alwaysensure
compliance with the current VDE and EN standards (EN 12453:2000) and the technical
criteria for connection as required by the regional electricity supply companies.
Before connection, check that the permissible mains voltage range of the control unit is
compatible with the local mains voltage.
Install the control unit and external command devices in the door area so that the door
can be watched during operation. However, they must not be installed within the range
of movement of the door.
Static electricity can damage the electronic components on the circuit board. Before
touching the circuit board, touch a metallic, grounded object to ensure that you are free
of electrostatic charge.
The control unit may only be operated in automatic mode in conjunction with
safety devices (minimum requirement: "safety contact strip"). If there are no
safety devices, the control unit may only be operated in dead man mode!

Only cut as much off the cap on the cable conduit so that it will still be sealed after
the cable is inserted.
Always use a strain relief when connecting the cable (included in scope of delivery).
