1. Safety
System operation assumes knowledge of the operating instructions.
1.1 Symbols Used
The following symbols are used in these operating instructions:
Indicates a hazardous situation which, if not avoided,
may result in minor or moderate injury.
Indicates a situation that may result in property damage if not avoided.
Indicates a user action.
iIndicates a tip for users.
1.2 Warnings
Connect the power supply and the display/output device according to the safety regulations for electrical
equipment.
> Risk of injury
> Damage to or destruction of the sensor
The supply voltage must not exceed the specified limits.
> Damage to or destruction of the sensor
No sharp or heavy objects should be allowed to affect the cables. Avoid folding the cables. Do not bend
more tightly than the minimum bending radius of the cables.
> Damage or destruction of the cable, failure of the measuring device
Do not crush the cable. Protect the sensor cable against damage.
> Damage or destruction of the cable, failure of the measuring device, data loss
Ensure that the coupling nuts of the connectors are firmly tightened.
> Damage or destruction of the cable, failure of the measuring device

1.3 Notes on CE Marking
The following apply to the ACC5703:
- EU Directive 2014/30/EU
- EU Directive 2011/65/EU
Products which carry the CE mark satisfy the requirements of the EU directives cited and the European
harmonized standards (EN) listed therein. The EU Declaration of Conformity is available to the responsible
authorities according to EU Directive, article 10, at:

The measuring system is designed for use in industrial environments and meets the requirements.
1.4 Intended Use
The ACC5703 is designed for use in industrial applications. It is used for
measuring acceleration
measuring vibration of manoeuvrable components
- The system must only be operated within the limits specified in the technical data, see 2.3.
- The sensor must be used in such a way that no persons are endangered or machines and other material
goods are damaged in the event of malfunction or total failure of the sensor.
- Take additional precautions for safety and damage prevention in case of safety-related applications.

2. Functional Principle, Technical Data
2.1 Functional Principle
With the principle of an acceleration sensor, forces that change the velocity of an object are measured and
transformed into an electric output signal.
Therefore the sensor is mounted on the maneuverable component. The expected moves correspond to the
measurement axes. The included MEMS-Element converts the acceleration into a usable electric signal.

2.2 Structure and Electrical Connection
The sensor is ready for operation immediately after connecting the power supply and will provide the accel-
eration as electric value at the analog output.
The ACC5703 is available with analog (current, voltage and switching output) as well as RS485 interface for
configuring of the sensor using the software.
Power supply and signal output are connected through a 8-contact (M12) connector on the sensor’s housing.
