Table 3.3: Fuses
3.1.3 EMC-Correct Installation
Following these guidelines is advised, where compliance with EN 61000-6-3/4, EN 55011 or EN 61800-3
First environment
is required. If the installation
is in EN 61800-3
Second environment
, then it is acceptable to deviate from these guidelines. It is however not recommended.
Good engineering practice to ensure EMC-correct electrical installation:
•
Use only braided screened/armoured motor cables and control cables.
The screen should provide a minimum coverage of 80%.The screen material must be metal, not limited to but typically copper, aluminium, steel
or lead. There are no special requirements for the mains cable.
•
Installations using rigid metal conduits are not required to use screened cable, but the motor cable must be installed in conduit separate from
the control and mains cables. Full connection of the conduit from the drive to the motor is required. The EMC performance of flexible conduits
varies a lot and information from the manufacturer must be obtained.
•
Connect the screen/armour/conduit to earth at both ends for motor cables and control cables.
•
Avoid terminating the screen/armour with twisted ends (pigtails). Such a termination increases the high frequency impedance of the screen,
which reduces its effectiveness at high frequencies. Use low impedance cable clamps or glands instead.
•
Ensure good electrical contact between the de-coupling plate and the metal chassis of the frequency converter, see Instruction MI.02.BX.YY.
•
Avoid using unscreened/unarmoured motor or control cables inside cabinets housing the drive(s), where possible.
3.2 Mains Connection
3.2.1 Connecting to Mains
Step 1: First mount earth cable.
Step 2: Mount wires in terminals L1/L, L2 and L3/N and tighten.
