NOTE:
Ensure that the length of the connector does not exceed 1.57 in (40 mm).
1. Connect the Ethernet cable (see the specification table in this section) to its
terminal and run the cable through the rubber grommets as other I/O cables.
2. Do one of the following:
– Protection class Type 1/IP21: Cut free the opening on the drive cover for
the Ethernet cable.
– Protection class Type 12/IP54: Cut the rubber grommets open to slide the
cables through. Should the grommets fold in while inserting the cable, just
draw the cable back a bit to straighten the grommets up. Do not cut the
grommet openings wider than what is necessary for the cables you are
using.
NOTICE
To meet the requirements of the enclosure class Type 12/IP54, the connection
between the grommet and the cable must be tight. Therefore, lead the first bit of
the cable out of the grommet straight before letting it bend. If this is not possible,
the tightness of the connection must be ensured with insulation tape or a cable
tie.

Remount the drive cover.
