Installation position for operation with or without fan

Note

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.

Recommended distances of installation position for operating without fan

Compliance with the distances shown in Fig. “Recommended distances of installation position for operating without fan” is recommended.

For further information regarding the operation without fan refer to the Technical Data of the terminal.

Standard installation position for operation with fan

The standard installation position for operation with fan requires the mounting rail to be installed horizontally and the connection surfaces of the EL/KL terminals to face forward (see Fig. Recommended distances for installation position for operation with fan).
The terminals are ventilated fan supported (e.g. with fan cartridge ZB8610) from below.

Other installation positions

Due to the enforced effect of the fan on the ventilation of the terminals, other installation positions (see Fig. “Other installation positions, example 1 + 2“) may be permitted where appropriate.

See corresponding notes in the Technical Data of the terminal.
