disconnecting from the power supply.
Notes on proper installation:
Use fuses at power line.
Check the wires condition before operating. Make sure that there are no short circuits.
Use cables fulfilling the voltage, current, load and insulation installation requirements.
Use only high quality hard wire or fiber copper wire with ferrule.
Use shield cable.
Make sure that motor label plate specification matches the operating supply voltage. Use cables that are
adapted to work with the desired current.
Stepper motors used in series of VTS Heat Exchangers (Figure 7) are connected and powered via controller responsible
for basic operational parameters. Motor itself is equipped with male type terminal which characteristic are described
below in the Figure 8.
