as there is no interference from indoor or outdoor.
4. Set up a secure communication method such
as data encryption.
• Encrypt data in every environment, including IoT
networks, secure gate-way connections, for secure
communications.
5. Grant access permissions by user accounts
and limit the number of users.
• Regularly review accounts and delete all unused
accounts or permissions.
• Establish an account lockout system to block an
access to the account for a certain period if log-in fails
more than the given threshold.
6. Protect passwords.
• Change the default password when you first use
the device or system.
• Choose a long password (minimum 8
characters) using a mix of different letters and
characters to make the password more secure
and harder to hack.

3.2.1. PROFINET/Power connection
The SI Unit has two PROFINET communication connectors. If only one connector is used, cover the
unused connector with a seal cap so that the protection rating of IP67 is maintained.
Caution
Seal caps must be fitted to all unused bus connector ports to ensure an IP67 rating.
IP67 rating must be maintained to guarantee PROFIsafe functionality.
For reasons of EMC a secure connection to the cable shield must be established on the M12 PROFINET
connectors (BUS IN/OUT).
Power and PROFINET cables must be installed correctly.
The 24 V supply for logic (PWR connector) and the 24 V supply for the valves (PWR(V) connector) should
be protected with an external fuse.
All external supplies should have the 0 V connected to functional earth according to EN 60204-1.
Afunctional earth cable must be connected to the M3 terminal.
If this product is connected using power cables that are more than 30 m long or go outside of a building
then external protection devices should be added to protect against electrical surge damage.
