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
increased pitch), an end plate, or a
partition between the different block
groups, in front of or behind the
cross-connected terminal block group.
