WIRING INSTALLATION
ELECTRICAL CONNECTION
SAFETY PRECAUTIONS:
• You must disconnect all supply circuits before
opening the enclosure to access the terminals!
• Any wiring, testing and maintenance work on
an open controller shall only be performed
when power has been turned off.
• When the controller has been turned off,
dangerous voltage levels can still be present
for up to 5 minutes.
• There is no isolation between the power stage
and the motor terminal.
• Touching electronic components is dangerous
due to residual voltages.
• Before switching on the gate controller for the
first time and after completion of the wiring,
check whether all connections are tight.
• Before turning on the controller’s supply for
the first time, make sure that the detector/
sensor cards (plug-in modules) are inserted
in the right places. Incorrect insertion of the
cards may damage the controller, as well as
the installation of non-approved third-party
equipment.
• After completing the installation, check the
correct configuration of the system and the
proper functioning of the safety systems.
Parameter settings and the speed as well as
the operation of the safety devices must be
checked.
• Switching on or operating the controller
when condensation is present is not
permitted. This can destroy the controller.
• The controller may only be opened if the
supply voltage has been switched off on all
poles.
• Never operate the controller without
connecting the protective earth conductor.
The absence of a protective earth conductor
will result in hazardous voltages on the
controller’s enclosure due to high leakage
capacitances.
• Hazardous voltages remain stored in the DC
bus capacitors for up to 5 minutes after power
has been turned off. The discharge time until
voltages fall below 50 VDC is a maximum
of 5 minutes. Touching internal controller
components within this discharge time is
hazardous.
• A defective switching power supply can
considerably increase the discharge time of
the DC bus capacitors before reaching a voltage
less than 50 VDC. In this case, discharge times
of up to 10 minutes may be possible.
• If the voltage of the 24 V regulator is short-
circuited or overloaded, the switching power
supply will not start up even though the DC
bus capacitors are charged. The displays
remain off. The power supply can only be
restarted after eliminating the short circuit or
overload condition.
• Screw the cables to the terminals before
placing the terminals on the pin connectors.
This ensures safe contact between terminals
and connectors.
