2. Control unit ST 63 control unit for folding and swing gates
• To ensure a perfect operation, an all-current-sensitive residual current circuit breaker
type B must be used!
Warning
• Before connection works or taking o
the control cover, the mains switch
must be turned o!
• If the control is power supplied, its inner part is under
tension.
• In order to avoid electrical strokes, the safety regula-
tions have to be kept.
• The device may only be connected by trained profes-
sionals.
• The product is not suitable for installation in
explosion-hazardous areas.
• An all-pole disconnecting mains switch with a contact
opening gap of min. 3 mm has to be foreseen. The
gate facility has to be secured according to the valid
safety regulations!
• IMPORTANT: The control lines (sensor, buttons, ra-
dio, photocells, etc.) have to be laid separately from
the 230V lines (supply line, motors, signal lamp).
DANGER NOTES - Use of frequency converter
• Read this manual carefully before installing and using the converter. Installation, ajdustment, repair and
maintenance have to be made by professional sta.
> The non-compliance of the following instructions
leads to death or perilous injuries !!!
LOOK UP TO CONTINUOUS EARTHING
• An oxidated cooling element can form a confining layer to the mounting plate. Take implicitly the
suggested earthing connections into account!
ACCIDENTAL USE OF DEVICE
• Read this manual carefully before installing and using the converter.
• Adjustment of parameter settings have to be done by trained professionals.
DANGER OF ELECTRIC SHOCK OR ELECTRIC ARC AND EXPLOSION
• Read this manual carefully before installing and using the converter. Installation, ajdustment, repair and
maintenance have to be made by professinal sta.
• The user is responsible for the compliance of all relevant international and national electrotechnical rules/requirements
regarding the protection earthing of all devices.
• Numerous components of the frequency converter, including the printed circuits boards, are being supplied through the
mains voltage. DO NOT TOUCH ! Only use electrically isolated tools.
• Do NOT touch non shielded elements or bolt connections at terminals with mains voltage on
• DO NOT short-out the clamps PA/+ and PC/- or the DC-Bus-condensers.
• Before maintenance of converter:
- Cut o any power supply (also external of control device).
- Put a warning signboard with „DO NOT TURN ON“ onto the power switch or circuit breaker.
- Lock the power switch or circuit breaker in open position.
- WAIT 15 MINUTES so that the PC-Bus-condensers can discharge.
- Measure the voltage supply of DC-Busses between clamps PA/+ and PCI-, to make sure that the voltage is under 42 Vd.c.
The LED´s of converter can not show whether there is no DC-bus supply.
- Should the DC-Bus-condensers not fully discharge please contact manufacturer. Do not try to repair yourself.
• Mount all covers and before switching on the supply or before starting and stopping the converter.
