VLT ® types 3002-3008, 400/500 V, and
VLT ® 3002-3004, 200 V, with IP 54 en-
closure have a plastic base with holes
marked for cable unions.
Note that for the above VLT
and 500 V (UL-approved) a metallic
bonding plate is included in the plastic
base. The metal plate is used to terminate
cable conductor or armouring. See the
information on p. 148 concerning connec-
tion of the bonding plate when IP 00 VLT
are converted to IP 21 enclosure with UL
approval.
The cable unions mechanically support the
cables for IP 21/54 enclosure. For the
IP 00 version, the cables must be relieved
by other means (cable stirrups). The
cables end in removable plugs.

VLT 3011-3052, 400/500 V, and VLT
3006-3022, 200 V, have a metal base with
cut-outs for cable lead-through.

The bottom of the VLT types 3032-3052,
230 V, and VLT ® types 3060-3250 has a
plate mounted with 6 cross-head screws.
The plate can be removed to ease installa-
tion of the cable unions. After cable lead-
through has been completed, the plate
must be screwed back in place to ensure
correct IP enclosure grade and cooling.

The plate in the right-hand side of the
® ®
s for 200 V VLT enclosure can be removed, and the
hole can be used for cable lead-through if
an extra enclosure or an IP 54 RFI module
is required. If one of these modules is to
be used, the right-hand side of the VLT
enclosure may not be bored for other
®
s cables.
The VLT
avoid metal flakes flying into the VLT
