Electrical connection
•
Any wiring, testing and maintenance work on an open
controller shall only be performed when power has been
turned off. Pay particular attention to the points shown
under "Safety information".
•
The controller must never be operated while it is open.
•
When the controller has been turned off, dangerous
voltage levels are still present for up to 5 minutes.
•
During the downtime, no isolation exists between the
amplifier module and the motor terminal.
•
Touching electronic components is dangerous due to
residual voltages.
•
Never operate the controller while the cover is removed.
•
When the installation was completed, check that the
system was configured correctly and that the safety
system works properly.
•
The controller may be opened only if all the poles of the
supply voltage have been turned off. It is not permitted to
turn on or to operate the controller when it is open.
•
Never operate the controller without having connected the
protective earth conductor. The absence of a protective
earth conductor will result in hazardous voltages on the
controller housing caused by terminal capacitances. The
RFI filters integrated into the controller may increase the
leakage current up to a max. of 7 mA (see DIN EN 60335-
1 section 16.2). A corresponding routine test was carried
out by the manufacturer before delivery of the device.
•
Hazardous voltages remain stored in the DC-bus
capacitors for up to five minutes after power has been
turned off. The discharge time until voltages fall below 60
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 60VDC. In this case,
discharge times of up to 10 minutes may be possible.
•
The processor circuit is galvanically connected to the
power line. Important: when taking measurements on the
processor circuit, do not use test equipment with PE
reference to the measuring circuit.
•
The controller must never be operated with a damaged
membrane keypad or Display window. Damaged keypads
and Display windows must be replaced. To prevent
damage to the keypad, do not use pointed objects to
operate the keys. The keypad is only designed to be
operated by human fingers.
•
If the potential free contacts of the output relays or other
terminals are supplied by an external voltage, i.e.
dangerous voltages that are still present after switching off
the controller or disconnecting power, you must attach a
suitable warning sign to the housing.
Disconnect all supply circuits before opening the
housing for access to the terminals.
•
When moving the door in deadman mode, ensure that
the operator has an unobstructed view of the door area,
since in this mode safety equipment such as safety
edge and photo eyes are defeated.
•
Parameter settings inclusive the speed as well as all
operations of the safety devices must be checked. The
setting of parameters, bridges and other operating
elements may only be carried out by qualified
specialists.
•
Before turning on the controller for the first time and
after completion of the wiring, check whether all motor
connections are tight on the controller and the motor
side and whether the motor is correctly wired in star or
delta configuration. Loose motor connections usually
damage the inverter.
•
If the 24 V controller voltage is short circuited or
overloaded, the switching power supply will not start up
even though the intermediate circuit capacitors are
charged. The displays remain turned off. The power
supply can only be restarted after eliminating the short
circuit or the overload condition.
•
To fulfill the conditions of the EMC Directives, only
shielded and separate motor conductors must be used,
with the shield connected on both ends (motor and
controller side) and without any additional connections
in the line. Maximum cable length: 30 m
•
Fast running plastic foil doors may produce very high
electrostatic charges. A discharge of these voltages
may damage the controller. Therefore suitable
measures must be taken to prevent electrostatic
discharge.
•
Turning on or operating the controller in the presence
of condensation is not permitted. It can lead to the
damage of the controller.
•
Before turning on the controller supply for the first time,
ensure that the detector/sensor cards (plug-in
modules) have been inserted in the correct locations.
Incorrect insertion of the cards can result in damage to
the controller, likewise the installation of non-approved
third-party equipment.
•
First connect the cables to the connection terminals
and then attach them to the connectors! Only thus is it
possible to ensure a safe contact of the connection
terminals to the plug connectors.
