Engineering notes • The module is intended for I.S. 1 field stations and may only be installed in Zone 2 / Division 2 or
in the safe area. For use in Zone 2, an enclosure with degree of protection of at least IP54 is
required. The module is plugged onto the BusRail of the I.S. 1 system.
• It is recommended to position the module 9477/15 next to the CPM (9440). In order to maintain
the distance of ) 50 mm / 2 in to the connection terminals of the I.S. module, a partition (162740)
is required.
• Non-intrinsically safe circuits may be connected to 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 2 A (e.g. fuse or current limitation).
