12 FRC-Q with integrated drive contactors
12.1 General
The frequency converter can also be supplied with integrated drive contactors. The drive contactors
correspond to utilisation category AC3 and are fitted with auxiliary contactors.
A
Plug & Play system
is being offered where the frequency converter is just plugged into the control
system. This avoids any possibility of wiring mistakes on site. Until now, the interface between the
elevator control and the VVVF is realized with nearly all control-manufacturers.
The complete unit is enclosed in a housing so that it can be fastened to a wall outside the enclosure.
The braking resistance (max. 20% duty cycle) is integrated in the unit up to size 5.
From size 6 and for duty cycles > 20%, the braking resistor must be placed externally.
Warning: Due to the heat dissipation of the brake resistor the unit should always fixed on an
inflammable base (e.g. concrete wall). For proper ventilation of the braking resistance there should be
at least 100cm space above and below the unit.
Above the device / brake resistor, there must not be any inflammable objects.
If the above instructions are not followed, there is the RISK OF FIRE!
12.2 Technical Specification
The currents correspond to that of the standard unit.
