Special safety instructions

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.

Danger!

Duty of care Take care when working on the system and always check that the system and the modules themselves are in perfect condition, as well as ensuring that they are properly installed and correctly attached to the DIN rail. If damage to cables, devices, supplies or enclosures is detected before commissioning or during operation, the system must not be put into operation or must be taken out of operation immediately.

Warning!
	Compliance with the supply voltage range A higher supply voltage may destroy the device! Never supply the device with a voltage other than 24 V DC!

Warning!
	This is a class A device. This equipment may cause radio interference in residential areas. In this case, the operator will be required to take appropriate measures.

Warning!

Mounting and dismounting / Disconnection from the grid Work on the device or system may only be carried out when the power is switched off! Due to the modular concept of this system, modules connected in series with this module can also carry dangerous voltages. All energized components of all modules in the system must therefore be disconnected from the grid before mounting and dismounting. In addition to disconnecting the power supply at the system's central unit, the signal plugs and connections of all modules in the system must also be de-energized or disconnected from the grid.

Caution!
	A suitable disconnecting device for this system must be available and disconnect all energized components of this system. This disconnecting device must include a switch or circuit breaker that is easily accessible at a suitable location in the vicinity and is also clearly marked as a disconnecting device for this system.

Caution!
	Supply and measuring cables Do not use damaged supply and measuring cables. Do not connect or disconnect supply and measuring cables when the device is connected to the power. Supply and measuring cables must be suitable for the corresponding voltages.

Caution!
	You must only connect one conductor to each terminal connection. Several individual conductors, whether single-wired or fine-wired, are not permitted. Only connectors classified by iba may be used for connecting conductors.

Caution!
	Hot surfaces Individual device surfaces can become very hot. Observe the danger sign "Warning of hot surface": The cooling fins of the device can become very hot. Make sure that the cooling fins get optimal ventilation. Observe the specifications for the installation clearances of the entire system.

Note
	Do not switch off the device uncontrolled, e.g. by disconnecting the supply voltage. This can lead to data loss. Always shut down the device properly.

Note
	A power supply unit with safety extra-low voltage and appropriate power limitation must be provided as power supply. Protect the device against uncontrolled power dips/drops of the power supply unit with an uninterruptible power supply (UPS).

Note
	Do not open the device! Opening the device results in a loss of warranty!

Note
	The device does not require any special cleaning or maintenance! However, if you want to carry out an inspection, return the device to iba.
