Safety Regulations; Supplying Power To The Pss - Pilz PSS Series Installation Manual

Safety Regulations

To ensure that the safety system functions correctly, please follow the
safety guidelines given below:
• Electrical connections should be made by a qualified electrical engineer
who is familiar with the information in this manual as well as the relevant
regulations concerning health and safety at work.
• Ensure VDE and local regulations are met, especially those relating to
safety. The relevant safety regulations for the respective application
must also be met.
• CAUTION!
Electrostatic discharge can damage components on the PSS. Ensure
against discharge before touching the terminal strips, e.g. by touching an
earthed, conductive surface or by wearing an earthed armband.
• Ensure all the requirements of the relevant trade associations are met.
• Ensure the wiring instructions in Chapter 5 are followed.
• The internal power supply on the safety system must not be connected
to any other devices.
• If the system is altered in any way, such as exchanging a component or
carrying out soldering work, the guarantee, and any approval, will be
rendered invalid.
• The date of manufacture can be found on the test label.

Supplying power to the PSS

• The safety system requires a 24 VDC supply.
Check that the voltage supplied from the external power supply
corresponds.
• CAUTION!
The tolerance on the supply voltage for the system's power supply is
+10 % or -15 % maximum. Safe operation cannot be guaranteed outside
this range.
• Overvoltage and spikes of interference can damage the PSS power
supply. If this occurs the unit will switch to a safe condition. Please refer
to the relevant EMC-measures described in Chapter 3.
