5.3 Wiring Guidelines for Compliance with the EMC Standards
The inverter was tested according to EMC product standard EN 61800-3 (variable-speed electrical drives).
• The above-mentioned EMC product standard can be complied with only by means of shielded motor
and control cables. It should be ensured that the cable shields rest over a large area of the inverter
housing and are surrounded by the cable clips. A shielded mains cable is not required.
• The control cables must be laid separately from (not parallel with) mains and motor cables. Shielded
cables and metalized plug housings should be used.
• All devices in the mounting cabinet should be connected over a large area to a common earthing point
via short earthing cables.
• On installation of the inverter, valid safety provisions may on no account be infringed.
5.4 Electrical Connections
Access to the electrical connections
Connection area for frequency inverter e@syDrive 4425, 4426
For frequency inverter e@syDrive 4425, 4426 the supply cable is connected to "In sek." (2) and "PE" (1).
The cable shield is to be neatly clamped under the traction relief.
When the enclosed version is selected, ensure that both covers are conductively well connected
together (either via the switchbox or other appropriate means).
Motor Connections
The motor is connected to "U, V, W" (1).
It is possible to connect position sensors to hall "U, V, W" (4), and their electrical supply to "12 V" or
"GND" (3).
A motor-temperature sensor is attached to "PTC" and "GND" (2).
Plug type: spring-clip (max. 2.5 mm
