2.2.3 Braking Resistor
The external Braking resistor unit is connected to terminals 1 and 2 of the terminal
strip X2 and to the adjacent PE terminal.
If mounted on the top of the control and twisted. If mounted separately near the
control cabinet the connecting cable must be screened.
DANGER!
When the Inverter is switched on, this external Braking Resistor Unit is
charged with 600 V DC !
Even a long time after switching the Inverter off, a charge may still be
present. This applies particularly when there is some defect in the
system.
An appropriate Warning Notice must be displayed in the control cabinet !
2.2.4 Internal Voltage
The voltage adaptation for the internal fan and for the internal electronic voltage is
made by an appropriate bridge on the terminal strip X3. (L-380V, L-400V or L-415V)
2.2.5 Extra Motor Cooling Fan
If a separate cooling fan on the motor is needed, this is to be switched directly
through the elevator control unit.
2.2.6 Size of Cables
The cross-section of all cables must be proportionate to the various currents in the
unit:
