5. Electrical connection and fieldbus connection
5.1. Electrical connection
Live parts are opened. Risk of direct contact!
Failure to observe this warning result in death, serious injury, or property damage.
→
The electrical connection must be carried out exclusively by suitably qualified
personnel.
→
Prior to connection, observe basic information contained in this chapter.
The connecting cables must comply with the requirements in terms of electrical
connection data and load (mechanical, thermal and chemical). It is recommended
to use shields for all connecting cables with the exception of the main power supply
and to use the provided terminals for the shield.
Wiring diagram/terminal
plan
The relevant wiring diagram/terminal plan for SIMA² is supplied in a separate cover
and may also be requested when indicating the order number (refer to name plate).
Power supply
SIMA² Master Station can be provided for different supply voltages. Prior to
connection, check whether the supply voltage matches the specified voltage.
For further details, please refer to technical data.
Mains connection
Ensure that the device’s power switch is set to OFF prior to connecting the power
supply.
The voltage values for the device supplied are available on the name plate.
Depending on the mounting position, lateral mounting of the mains cable is possible.
However, this modification may only be performed by the AUMA Service.
5.2. Earth connection
The SIMA² housing must be earthed using the earth wire available with the connecting
cable or via the earth connection via a separate cable.

5.3. Shield connection
The fieldbus cable shield must be connected at both ends. The shield brackets within
SIMA² or appropriate EMC cable glands at the control cabinet input can be used for
connection.
5.4. Lightning protection
EIA-485 interfaces are galvanically isolated from the remaining electronic components
of SIMA². Additional lightning protection measures are not available with the standard
SIMA² version. If stronger lightning protection is required, further protective measures
