Installing the Metal (EMC) Cable Gland for the Motor Cables on IP54 Inverters 7.5 to 30kW:
•
With the standard contacting
Make a round cut into the outer sheath, with
a length of appr. 14mm from the end of the
sheath but do not remove the sheath. Guide
the cable through the gland.
Pull off the cut-off outer sheath, remove
some part of the shield and pull the cable
back until the shield has proper contact to
the springs of the cable gland.
Close the cable gland.
•
With thin wires and without an inner sheath:
Make a round cut into the sheath, with
a length of appr. 15 to 20 mm and remove it.
Pull back the braided shield over the outer
sheath, the inner shield should be kept for
easier guiding through the gland.
Guide the cable through the gland until the
shield has proper contact to the springs of
the cable gland and close the cable gland.
Note: To ensure conformity to EMC regulations the shielded cable has to be locked tightly by the
metal cable gland. Confirm the cable length and the terminal specifications before fitting the metal
cable gland.
Special Considerations for IP54 Inverters of 22 and 30kW capacity
Remove the braided shield on the output cable entirely from the entry hole to the terminal end to
avoid short circuit to the input terminals or the filter.
