2.3 Cable connections
2.3.1 Motor
The motor is delivered with fixed connected motor cables to simplify
installation of the drive system. The length of the cables is 2.5m.
In order to secure the function of the drive system, do not change the length of
the motor cables.
2.3.2 Mains supply
An external slow-blow fuse rated at <6 A must always be installed on mains
supply. The drive system does not contain a fuse. Electronic motor protection is
built into the control unit, and monitors the motor at all times. The control
unit is protected from short circuit within the motor.
Connect the mains cables according to Fig. 7 and Table 4.
2.3.3 Communication connections
For communication signals, the used RS485 cable type should preferably be
screened and of twisted pair type to avoid EMI. The cable should be placed at
least 20 cm away from any power cables. Drop cables shall be avoided to the
extent possible. It is recommended to connect the screen of the cable to chassis/
mounting plate near to the EMX-B gland.
WARNING! Do not install a switch between the motor and the
control unit.
