3.2.4 Installing cable glands (IP66)
A total of six cable glands can be installed on the variable frequency drives
with an IP66 degree of protection. The lower section has two knockouts for
cable glands that are already open and that are intended for connecting the
power section.
The center knockout in the lower section is intended for an
external braking resistance. The lower housing cover has three additional
knockouts for routing control and bus cables.
Use a standard screwdriver to punch out the knockouts. While doing so,
make sure not to damage any internal terminal box parts.
