Elektrical / Mechanical installation
Important
A time delay of approx. 5 - 30 sec will occur at start up. If the PCB is dismounted from the metal housing,
the warranty will be void. Before handling the frequency converter, it must have been disconnected from
supply power for at least 5 minutes.
Mounting
The frequency converter is cooled by passive air circulation. To avoid reduced operation or operation stops
due to overheating of the frequency converter, the frequency converter must be mounted vertically on a
metal plated wall with the cable glands facing downwards. The frequency converter must be mounted
with space around it to ensure sufficient cooling by allowing free circulation of air.
Do not place the frequency converter in a cupboard unless it is well ventilated. The ambient temperature
must not exceed 40°C, and the frequency converter must not be exposed to direct sunlight.
Supply
The frequency converter is supplied by mains (230VAC ±10%) with minimum 3 x 1.5 mm2 cable. The
distance between supply cable and motor cable must be as long as possible (> 30 cm). If it is necessary to
cross the power cable and the motor cable, this must be done at an angle of 90°. The PE-conductor from
the motor must be longer than L and N.
Due to relatively high leakage currents in the frequency converter and the motor, the frequency converter
and the motor must always be properly grounded in accordance with national and local regulations. The
ground conductor should be as short as possible to avoid high frequency radiation.
Motor
The motor is connected to the frequency converter by minimum 4 x 1.5 mm2 shielded cable. The total
cable length must not exceed 20 m, keep it as short as possible. Long cables may cause function failure.
The motor cable must be shielded and be mounted correctly in the metal gland to minimize electrical
noise from the motor. The PE conductor must be longer than U, V and W. If the motor is rotating in the
wrong direction, change the position of two of the motor cables.
Signal cables
The distance between the signal cable and the motor cable and supply cable must be as long as possible (>
30 cm). If the signal cable crosses the motor cable or the supply cable, it must be done at an angle of 90°.
The signal cable must be shielded to GND or PE.
Current limits
The current limits are controlled by Jumper 2. If JP2 is closed, the motor current will be adjusted for
operation of 550W motors (2,9A). If JP2 is open, the motor current will be adjusted for operation 750W
motors (3,8A).
