2.3 ELECTRIC INSTALLATION OF THE SAFETY SWITCHES
All the works concerning the electrical equipment should only be carried out by specialized electri-
cians, skilled workers.
Before beginning operations, turn off the power of all the parts of the system.
When laying the connection cables, take care that:
- unipolar cables have a double coating
- the use and laying of the cables are carried out according to the EMV rules and regulations.
The safety switches disconnect the safety circuit of the elevator plant.
The following safety switches must be connected:

SETTING UP OPERATIONS
3.1 OVERSPEED GOVERNOR
The safety switch of the overspeed governor has already been set in the factory. Its position is fixed with sea-
ling-wax and it cannot be modified.
The setting up of the safety switch on the overspeed governor is not necessary.
3.2 TENSION WEIGHT WITH COUNTERWEIGHT (EN 81 AND TRA)
REGULATION OF THE SAFETY SWITCH
Only in plants in conformity to EN 81:
• shift the mounting clamp of the tension weight with counterweight in such a way that the safety switch does
not become operative (fig. l, pos. 1).
At the same time take into consideration the stretching of the rope!
• On the safety switch, adjust the horizontal connecting position on the slots (fig. 1, pos. 2);
• After the assembly, release the tension rope and check the control function by moving the tension arm. Then
fix the position with sealing-wax or similar.
• After the insertion, the tripping pin of the safety switch must be reset by hand in the starting position.
