53 • Starting Procedure
6. STARTING PROCEDURE
Note:
It is necessary to connect a motor to load terminals; otherwise Shorted SCR or WRONG CONNECTION faults are
activated (OC or Wrong CON.). Other loads such as incandescent light bulbs, resistors, etc. may also cause an OC
or Wrong CON. fault.
1 When mains voltage is connected to the ASTAT-XT, even if control voltage is
disconnected, full voltage may appear on the ASTAT-XT load terminals.
Therefore, for isolation purposes, it is necessary to connect an isolating
device upstream to the ASTAT-XT.
2 Power factor correction capacitors must not be installed on the load side of
the ASTAT-XT. When required, install capacitors on the line side of the ASTAT-
XT.
3 When using Inside Delta connection, wrong connection of the ASTAT-XT 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 ASTAT-XT.
WARNING
7 When the START signal is initiated and a motor is not connected to load
terminals, the SHORT SCR or WRONG CONNECTION (OC or Wrong
CON.) protection will be activated.
