Operating time
The operating time is the maximum time permitted on a sensor between actua-
tion of both sensor contacts.
With 2-hand operation, it is the maximum time permitted between actuation of
both sensors.
Safe condition
The safety outputs are opened or with high resistance.
Hazardous condition
The safety outputs are closed or with low resistance.

Installation


Danger of electrocution!
Ensure that the safety control unit is installed and put into
operation only by specially trained, authorized personnel.
Danger
- Installation of the safety control unit is only permitted in a voltage-free state.
- Ensure that the prescribed fuses
- Snap the safety control unit onto a mounting rail (DIN EN 60715 TH35) in the
switch cabinet. The safety control unit is fixed.
- Connect the safety control unit.
The pluggable terminal blocks can be coded by means of pins, the sockets
in the device are inversely coded by means of coding tabs.

10 Electrical connection

- Electrical connection is only permitted in a voltage-free state.
- Make sure that the details described in the technical specifications are al-
ways complied with.
- Measures to improve the equipment's immunity to interference from line-
conducted and radiated high frequency interference are to be taken
(DIN EN 60204-1:2007-06, para 4.4.2).
When connecting the sensor, the sensor power supply voltage (+) and (-)
terminals identified in the technical specifications are to be used.
