Installation Position For Operation With Or Without Fan - Beckhoff KL2532 Documentation

Mounting and wiring
Additional installation instructions
For terminals with enhanced mechanical load capacity, the following additional installation instructions apply:
• The enhanced mechanical load capacity is valid for all permissible installation positions
• Use a mounting rail according to EN 60715 TH35-15
• Fix the terminal segment on both sides of the mounting rail with a mechanical fixture, e.g. an earth
terminal or reinforced end clamp
• The maximum total extension of the terminal segment (without coupler) is:
64 terminals (12 mm mounting with) or 32 terminals (24 mm mounting with)
• Avoid deformation, twisting, crushing and bending of the mounting rail during edging and installation of
the rail
• The mounting points of the mounting rail must be set at 5 cm intervals
• Use countersunk head screws to fasten the mounting rail
• The free length between the strain relief and the wire connection should be kept as short as possible. A
distance of approx. 10 cm should be maintained to the cable duct.

Installation position for operation with or without fan

Constraints regarding installation position and operating temperature range
When installing the terminals ensure that an adequate spacing is maintained between other components
above and below the terminal in order to guarantee adequate ventilation!
Prescribed installation position for operation without fan
The prescribed installation position requires the mounting rail to be installed horizontally and the connection
surfaces of the EL/KL terminals to face forward (see Fig. "Recommended distances of installation position for
operating without fan").
The terminals are ventilated from below, which enables optimum cooling of the electronics through
convection.
