• Education and instruction as per the standards of safety engineering regarding the maintenance and use of adequate safety equipment.

• First aid training.

The following notes must be read prior to the initial operation of the system to prevent personal injuries and/or property damages:

	These safety notes must be complied with at all times.
	Do not try to install or commission the ADU before carefully reading all safety notes contained in this document. These safety instructions and all other user notes must be read prior to any work with the ADU.
	In case you do not have any user notes for the ADU, please contact your sales representative. Immediately demand these documents to be sent to the person responsible for the safe operation of the ADU.
	If you sell, rent and/or otherwise make this device available to others, these safety notes must also be included.
	The user must not open the ADU for safety and warranty reasons.
	Professional site layout and survey planning is a perquisite for sound operation of the ADU!

	DANGER! Inappropriate handling of the ADU and non-compliance with the warnings as well as inappropriate intervention in the safety features may result in property damage, personal injuries and electric shock.

EMC

The ADU system applies to class A of the DIN EN IEC 61000-6-4 2020-09 (commercial / industrial environment). As such it is not meant to be used in class B environment (home use).

Danger

DANGER! If the ADU is used during thunderstorms it can happen that a direct lightning strike hits a connection cable especially an electric field cable. This can destroy the system. If the ADU is operated during such conditions personal injury and even death of the operating person can occur. Operation during thunderstorms is not allowed.

Safety Notes

General Safety Notes

	Caution! The ADU-11e corresponds to IP 6 degree of protection as well as pollution degree 8. Make sure that the environment corresponds to this degree of protection and pollution degree (IP68).
	Caution! Only use replacement parts and accessories approved by the manufacturer.
	Information The safety rules and regulations of the country in which the device will be operated must be complied with.
	Caution! The environment conditions defined in the product documentation must be kept. Safety-critical applications are not allowed, unless specifically approved by the manufacturer.
	Information For notes on installation corresponding to EMC, please refer to chapter 8. The compliance with the limits required by national regulations is the responsibility of the manufacturer of the machine or system.
	Caution! The technical data and the connection and installation conditions for the ADU-11e are to be found in this product manual and must be met.
	DANGER! The general setup and safety regulations for work on power installations (for example DIN, VDE, EN, IEC or other national and international regulations) must be complied with. Non-compliance may result in death, personal injury or serious property damages.

	Information Without claiming completeness, the following regulations and others apply:
EN55011:2009 +A1:2010	Industrial, scientific and medical (ISM) radio-frequency equipment – Electromagnetic disturbance characteristics – Limits and methods of measurement.
EN61000-4-6-2014	Electromagnetic compatibility (EMC) - Part 4-6: Testing and measurement techniques - Immunity to conducted disturbances, induced by radio-frequency fields (IEC 61000-4-6:2013); German version EN 61000-4-6:2014

Safety Notes for Assembly and Maintenance

The appropriate DIN, VDE, EN and IEC regulations as well as all national and local safety regulations and rules for the prevention of accidents apply for the assembly and maintenance of the system. The plant engineer or the operator is responsible for compliance with these regulations:

	Caution! The ADU-11e must only be operated, maintained and/or repaired by personnel trained and qualified for working on or with the system.

Note

Prevention of accidents, injuries and/or damages

	Take care of heavy components, like MFS-06e/07e sensors. Getting hit by these components may cause serious injuries.
	Keep the electrical equipment voltage-free disconnecting the battery and protect it from being switched on, in the case of: Maintenance and repair work Cleaning long machine shutdowns
	Prior to carrying out maintenance work make sure that the power supply has been turned off and locked, batteries have been disconnected.
	The external supply battery may push very big currents, if being shorted.
	Be careful during the assembly. During the assembly and also later during operation of the ADU, make sure to prevent from being flooded by water (e.g. during very heavy rain fall). Additionally take care that the maximum ambient temperature of 50°C is not exceeded, e.g. by protecting the ADU against direct impact from the sun.
	Electronic devices are never fail-safe. It is the user’s responsibility, in the case an electrical device fails, to make sure the system is transferred into a secure state.

Protection Against Contact With Electrical Parts

The appropriate DIN, VDE, EN and IEC regulations as well as all national and local safety regulations and rules for the prevention of accidents apply for the assembly and maintenance of the system. The survey manager is responsible for compliance with these regulations:

	DANGER! Risk of electric shock! The external supply battery may push very big currents, if being shorted.

Protection against Electrical Shock By Means Of Protective Extra-low Voltage (PELV)

All connections and terminals of the ADU are at a level of +/- 12V DC and therefore are protective extra-low voltage.

It is designed safe from contact in correspondence with the following standards:

• International: IEC 60364-4-41

• European countries within the EU: EN 61800-5-1

	DANGER! High electrical voltages due to wrong connections must be avoided! Danger to life, risk of injury due to electrical shock!

Only devices, electrical components and wires with a protective extra low voltage (PELV) may be connected to connectors and terminals with voltages between 0 to 50 Volts.

Protection against Dangerous Movements

Not applicable as the ADU does not contains any moving parts.

Protection against Contact with Hot/cold Parts

	DANGER! In case the ADU is operated during very hot/cold weather the housing parts of the ADU may get very hot/cold. In this case the risk of injury is given, if the system is touched.

Protection during Handling and Assembly

Handling and assembly of certain parts and components in an unsuitable manner may under adverse conditions cause injuries.

	DANGER! Risk of injury due to improper handling! Personal injury due to pinching, shearing, cutting, crushing!

The following general safety notes apply:

	Comply with the general setup and safety regulations on handling and assembly.
	Use suitable assembly and transportation devices.
	Prevent incarcerations and contusions by means of suitable protective measures.
	Use suitable tools only. If specified, use special tools.
	Use lifting devices and tools appropriately.
	If necessary, use suitable protective equipment (for example goggles, protective footwear, protective gloves).
	Do not stand underneath hanging loads.
	Remove leaking liquids on the floor immediately to prevent slipping.
