Mounting instructions for
EEx e applications
– If feed-through blocks are mounted
directly adjacent to feed-through blocks
of a different size, or directly adjacent
to ground blocks, the open side of a
group of the same type of blocks has
to be covered by an end plate or
partition.
– If neighboring terminal blocks are
jumpered by a cross connector, the
required isolation distances have to
be maintained by inserting either a snap-
in partition plate (without increasing
pitch), an end plate, or a partition
between the different block groups, in
front of or behind the cross-connected
terminal block group.
