Installing the terminal

1

Overview

The mechanical and electrical environmental conditions at the installation site must be within
permissible range according to the technical data of the terminal. Dusty, damp places, places li-
able to rapid temperature variations, powerful vibrations and shocks, surge voltages of high am-
plitude and fast rise time, strong induced magnetic fields or similar extreme conditions should
be avoided.

Sufficient space must be available in front of and at rear of the terminal to allow access for main-
tenance and future modifications. Flush mounted terminals should be mounted so that terminal
modules can be added and replaced without excessive demounting.
