Attention

Exceeding the maximum process or supply voltage (< -35 V DC and > + 35 V DC) could lead to unrecoverable damage of the system.

Attention

For the supply of the modules, power supply units according to PELV or SELV specifications must be used.

Note

The creepage distances and clearances meet the requirements of the overvoltage category II, pollution degree 2.

Note

In order to prevent malfunctions, it is recommended, that the operating personnel discharge themselves prior to touching communication connectors or perform other suitable measures to reduce effects of electrostatic discharges.

Attention

:strong:Risk of malfunctions!

Unused slots for communication modules are not protected against accidental physical contact.

  • Unused slots for communication modules must be covered with dummy communication modules (TA524 TA524 - Dummy Communication Module to achieve IP20 rating.
  • I/O bus connectors must not be touched during operation.
