6 Electrical connection
The national and international regulations for the installation of electrical equipment must be adhered
to. Avoid contact with dangerous contact voltages.
u
Disconnect power.
u
Connect device, connection via Combicon connectors (pre-mounted).
u
To prevent negative effects on the functions caused by noise voltages, lay sensor cables and load
cables separately. Maximum length of the sensor cable: 250 m.
u
Use a screened sensor cable.
The outputs are short-circuit proof and can be configured as either normally closed or normally open.
In addition an analogue signal can be provided on output [OU 1] (0/4...20 mA) (e.g. acceleration
values).
Adhere to the SELV criteria (safety extra-low voltage, circuit electrically isolated from other circuits,
ungrounded) when connecting the device, so that no dangerous contact voltages will be applied to the
sensor or transferred to the device.
If the DC circuit is to be grounded (e.g. due to national regulations), the PELV criteria must be adhered
to (protective extra-low voltage, circuit electrically isolated from other circuits).
Sensor and diagnostic electronics supply are not electrically isolated.
