Electrical connection
ATTENTION
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 controllers 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).
Prior to delivery, the manufacturer will test individual
units in this respect.
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.
ATTENTION
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.
Parameter settings and insertion of jumpers shall only
be performed by properly trained persons.
WARNING
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 connections to the motor
usually result in damage to 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 foildoors 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. This can result in the
destruction of the controller.
Before turning on the controllers 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.
Connect connection terminals before connecting to the
plug connectors! Only thus is it possible to ensure a
safe contact of the connection terminals to the plug
connectors.
