BUDDYBOX Operating Manual
6.7 Installation with frequency inverter
For operating motors with a frequency inverter please follow EMC instructions of the frequency
inverter.
Screened cable and metal cable glands are required.
The output torque of the motor depends on the type of frequency inverter in use.
The rectier of the brake requires a separate power supply.
The motor must be protected against overheating by PTC resistor, thermal contacts or forced
ventilator.
6.8 Motor protection
Motor protection switches (overload circuit breaker) must be adjusted to the current according
to the voltage indicated at the rating plate.
Thermal contacts are break contacts (NC) as standard.
The resistance of PTC thermistors at 20°C can vary from 90 Ω to maximum 750 Ω.
6.9 Forced ventilator
Connect the forced ventilator at the terminal box located on the ventilator cover.
A separate power supply should be provided for the ventilator motor.
CAUTION: Depending on the control in use, the ventilator may be running even when the motor
is at standstill.
Rating plates and circuit diagrams for forced ventilators are in the terminal box.
They vary according to the size. The ventilator motor can be congured as follows:
– Shaded pole motor: connection, L1 and N (reversal of rotation direction is not possible)
– Single phase motor:
left-hand motion right-hand motion
CCW CW
– Three-phase-motor: Star-connection or delta-connection, depending on voltage as indicated
in 6.5 electrical connection.
7. Start up
Before starting the motor, check once again all safety instructions.
Make sure that the power supply is in accordance with the characteristics indicated at the rating
plate. For additional devices, e.g. heater, see more details in the terminal box.
Connection cable diameters must be selected according to the motor power.
Installation is subject to all regulations and must be done by qualied personnel.
Before starting the motor review all safety regulations, check if the unit is properly installed and
aligned. Check all fastening parts and review if grounding is properly tightened. Also check
additional devices for proper function and connections and in the case of a second shaft end,
make sure that the key is secure.
If possible, start the gearmotor without load. If the gearmotor operates smoothly and without any
strange noise, connect to the machine. During the initial run-in check the motor input current
under load for possible over-current or phase asymmetry.
NOTE: All units are shipped without oil, for safety reasons. Please make sure gears are
properly supplied with oil before starting up.
