3.6.1.5 Cable glands IP66
In the case of units with an IP66 degree of protection, a total of six cable
glands can be installed. The lower section will come with two knockouts for
cable glands that have already been removed and that are intended for the
connections in the power section (Mains

). Meanwhile, the
center knockout in the lower section, which will not yet have been removed,
is intended for an external brake resistor. In addition, the upper enclosure
cover will feature three additional knockouts for routing control and bus
cables. If necessary, the corresponding plastic covers can be removed

.
Figure 44: Punching out the knockouts (Example)
Insert a plastic gland into the knockout on the left – which could already have
been punched out at the factory – in order to thread in the power supply
cord. Due to EMC reasons, you should use an metallic EMC cable gland in
the knockout on the right in order to connect the motor cable screen across a
large area and ground it.

Make sure not to damage any terminal box parts on the inside
when breaking through the plastic covers.
