Engineering notes • The module is intended for IS1 field stations and
may only be installed in Zone 1 or Division 1. This
requires installation in a suitable enclosure. The
module is mounted to the BusRail of the IS1 system
by means of base 9490/11-3. or 9490/12-3.
• Only non-intrinsically safe circuits may be connected
to the Ex e connection terminals or the pre-wired
cable of the module, provided that the maximum
values of current, voltage and power (refer to
technical data) are adhered to. The switching current
of the contacts must be limited to the value given in
the table (e.g. by fuse or current limitation).
