4.3 EMC Compliant Install for IP55 Units

5 Assembly - Notes

Make sure the D-type adapter is not lost! You will need it to connect the operator panel to the control unit

through the front lid on drive units 0.37kW to 15kW.

Using the optional shielding plate will depend on the installer’s preference. You should consider the number

of shielded signal cables - and therefore metal bonding glands required, compared to using nylon cable

glands and the shielding plate. Note that some kind of cable gland will always be required or the IP55/4

rating will be lost. Corrugated conduit adapters are not suitable as they do not seal out the humidity.
