Connecting the interfaces

7.8.1 Overview
DANGER
Risk of fatal injury due to electric shock!
Severe injury or death may result from improper use of the interface connections and failure to observe pro-
tection class III.
1. The SELV circuits (SELV: safety extra low voltage) can only be connected to other SELV circuits with protec-
tion class III.
CAUTION
Damage to the device from electrostatic discharge
Components inside the device can be damaged beyond repair by static discharge.
1. Observe the ESD protective measures.
2. Earth yourself before touching a component by touching a grounded object.
NOTE
Due to the installation position of the communication circuit board, this must be specially safeguarded against
moisture and exposure to dust.
1. Make sure that no moisture or dust impacts on the circuit board during installation. Moisture and dust
particles must be removed immediately. In doing so, disassembly of the circuit board may be necessary.
All interfaces are located on the communication circuit board (HMI board) inside the housing.
