Engineering
The following conditions must be observed during project engineering:
• To ensure adherence with the intended use, only install the device on the
IS1 BusRail 9494.
• Operation of the device is only permissible in three approved mounting positions:
See chapter "Mounting/dismounting on BusRail".
• Modules with intrinsically safe and non-intrinsically safe field circuits may be
operated simultaneously on one BusRail. In this case, a distance of 50 mm must be
maintained between the terminals with intrinsically safe field circuits and those with
non-intrinsically safe field circuits (e.g. partition 220101 or empty space).
Signal errors for

Mounting / Installation
Installation position
Horizontal or vertical (observe operating instructions)
Mounting type
on 35 mm DIN rail NS 35/15 (DIN EN 60715)
NOTICE
An ambient temperature that is too high may cause failure of the devices installed
in the cabinet.
Non-compliance can result in material damage.
• Install and adjust the cabinet in such a way that it is always operated within
the permissible temperature range.
