INSTALLATION AND CONNECTION
2. INSTALLATION AND CONNECTION
2.1. Acceptance and Unpacking
VS65 is usually transported upright. For the shipment abroad, the equipment may be placed
horizontally in a container.
Unpack the goods carefully and check for any damage taken placed during the transportation. In
case of damaged, please fill in a damage report within 15 days of reception of delivery order.
Confirm the received shipment accord with the ordered model. The product model is shown on the
label of the low-voltage control board.
2.2. Initial Inspection
Check whether there is damage during transportation and handling.
Check whether there is the loosen parts, broken wires, or loosen connections phenomenon during
the transportation and handling. The loosen connections should increase impedance and affect the
performance.
Before startup, please check and confirm the rated voltage and the rated current.
2.3. Operating Environment
The proper installing location can ensure its normal running and service life. VS65 softstarter must be
installed in an environment meeting these requirements:
Operating temperature: 0~50℃ (32°F-122°F) (running at -20℃ is acceptable if there is the
heating resistance) against rain and moisture.
Humidity: 5~95% non-condensing.
Keep away from the metal scraps, conductive dusts, and corrosive gases.
Oscillation (less than 0.5G).
2.4. Power Connections
Connect the 3-phase medium voltage power lines to the equipment’s input terminals L1, L2, and L3.
Connect the three phases of motor to the output terminals U, V, and W.
The copper bars or the cable must be complied with the standard of the current capacity and the
voltage isolation.
WARNING
Pressing the “Stop” button does not means to cut off the power supply, there is still high voltage
applied to the AC main loop. Prior to maintenance, it is necessary to switch off the main power
supply, i.e. turn off the main vacuum circuit-breaker, and put it at the test position. The WARNING
sign should be adhered on the panel of control cabinet and complied with the local electrical
regulations. It is forbidden to connect a capacitance power-factor compensator with the output of
VS65, otherwise will be resulted in the impact current that may damage SCR during starting. Do
not connect a capacitor to the output of soft starter. If PFC (power-factor compensator) is
necessary, please contact with the manufacturer. To avoid the wrong connection of the input and
output terminals; otherwise the logic control circuits will be damaged.
