8. STARTING PROCEDURE
Note:
It is necessary to connect a motor to load terminals; otherwise S.SCR or WRONG CONNECTION faults are
activated. Other loads such as incandescent light bulbs, resistors, etc. may also cause a WRONG
CONNECTION fault.
1
When mains voltage is connected to the RVS-DN, even if control voltage
is disconnected, full voltage may appear on the RVS-DN load terminals.
Therefore, for isolation purposes, it is necessary to connect an isolating
device upstream to the RVS-DN.
2
Power factor correction capacitors must not be installed on the load side
of the RVS-DN. When required, install capacitors on the line side of the
RVS-DN.
3
When using Inside delta connection, wrong connection of the RVS-DN or
the motor may damage the motor; therefore please confirm that the
motor is connected properly!
4
Do not interchange line and load connections
5
Before starting the motor verify its rotation direction. If needed,
disconnect the rotor from the mechanical load and verify the correct
direction of rotation.
6
Prior to start up procedure, make sure that line voltage and control
voltage match the ones shown on the name plate of the RVS-DN.
7
When the START signal is initiated and a motor is not connected to load
terminals, the SHORT SCR or WRONG CONNECTION protection will be
activated.
