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 the "Mounting/dismounting on BusRail" chapter).
• Modules with intrinsically safe and non-intrinsically safe field circuits may be operated
simultaneously on one BusRail.
6.1
Terminal Assignment
For the module, a pluggable terminal X1 (screw terminal 162702 or spring clamp
terminal 162695) for connecting field devices is available as an accessory
(not included in the scope of delivery of the module). The pluggable terminals have
16 clamping units for connection of the field cables.
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.

Channels may be connected in parallel to increase the power output.
This results in new technical data (see "Technical data" section).
