4.2 Notes on wiring
To ensure the correct operation of the safety light curtain, please note
the following:
•
Safe electrical isolation must be ensured for the external 24 V
supply. Failure to do so could result in electric shock. The supply
voltage must conform to EN 60950, 03/97, section 2.3, EN 60742,
9/95 or EN 50178, 10/97.
•
Emitter and receiver must be connected using shielded cables
(accessories).
FIg. 14 shows how to connect the emitter and receiver properly.
Fig. 15
•
At the point where the cable enters the cabinet, connect the screen
to the earth bar, without making a break in the cable. Use metal
cable clamps which cover the screen over a wide surface area.
•
Under no circumstances should the connection cables come into
contact with or be laid in proximity to cables that generate strong
electromagnetic interference (e.g.: motor feeds, inverters etc.);
these could compromise the device’s ability to function.
•
Multicore cables may not be used to connect the outputs of more
than one safety light curtain.
