Danger!

Operation The system must only be operated permanently connected and not touchable, only in a building (in-door) and only in a fire protection housing in accordance with IEC 61010-1. The system must only be operated with a mounted end cover. The external power supply/power supply unit for supplying the central unit and thus for the complete system must be tested for use with this system in accordance with IEC 61010-1. Modules from this system must only be operated with a central processing unit from this system. The supply voltage for this system must only be fed from this system via a central unit. The supply may only be provided via an energy-limited circuit in accordance with IEC 61010-1 and must either include a fuse that trips after 120 s at the latest in the event of an overcurrent greater than 4 A or limit the total current of the system to 4 A. In addition to their own current consumption from the supply voltage via the module-module interface, the central units and the modules also pass on the supply voltage for other connected modules, so that the module-module interfaces may have to carry the maximum specified total current of the system. Only a maximum of 15 modules may be installed next to the central unit.

The modular system is designed as follows and is to be mounted on the DIN rail:

• Central unit on the far left

• Up to 15 modules to the right of the central unit

• End cover on the far right to protect the contacts

Make sure that the modules

• are properly secured to the DIN rail and

• are correctly positioned in the side guide rails.

Check the correct fitting of the modules after mounting by a visual inspection.

Note
	An end cover is included in the scope of delivery of the central unit. The end cover is also available as an accessory or spare part from iba.

Installation clearances

Ensure a minimum clearance of the entire system of 30 mm upwards and downwards and 10 mm to the right and left for sufficient ventilation of the device.
