Assembly instructions for EEx e applications:

If modular terminals are arranged directly next to modular terminals of a different size or directly next to earth terminals, then the relevant open side of a block of terminals is to be closed off by means of an end section or partition.
If adjacent terminal blocks are bridged by a jumper bar, then a snap-in partition (without loss of spacing), end section or partition is to be placed between individual terminal groups or at the beginning and end of a bridged terminal group in order to maintain the required clearances.
