Installation position and minimum distances

Installation position
For the prescribed installation position the mounting rail is installed horizontally and the mating surfaces of
the ELX terminals point toward the front (see illustration below). The terminals are ventilated from below,
which enables optimum cooling of the electronics through convection. The direction indication "down"
corresponds to the direction of positive acceleration due to gravity.
Minimum distances
Observe the following minimum distances to ensure optimum convection cooling:
• above and below the ELX terminals: 35 mm (required!)
• besides the bus terminal block: 20 mm (recommended)

Observe the minimum separation distances according to IEC 60079-14!
Observe the prescribed minimum separation distances between intrinsically safe and non-intrinsically safe
circuits according to IEC 60079-14.
