Motor Wiring
The Motor wires are terminated into the terminals as shown.
Also check that the motor is correctly wired at the motor termination box
for the correct voltage.
If an output filter is to be installed refer to page 18.
NOTE: See below regarding requirement for installing motor cables.
Installation practices for Electromagnetic
Compatibility (EMC) Compliance
The EMC performance of the ECODRIVE is installation
dependent. For compliance with EMC standards, the use of a
screened power cable between the ECODRIVE and the motor
is required. Other suitable or approved arrangements may
also be used.
To achieve the required electrical performance at high
frequencies, it essential that:
• The screen has a 360 connection to both the ECODRIVE
gland plate and the motor terminal box.
•
The correct type of gland for the cable is used.
• The protective earth cable is terminated in the usual
way that meets local wiring codes.
•
The screen is continuous from the ECODRIVE to the
motor.
• Any isolation switches installed between the ECODRIVE
and Motor are enclosed in a metallic enclosure with the
screened properly terminated at both sides.
