SAFETY AND SECURITY

Physical device protection

Device shall be accessible to authorized personnel only –
Installation on publicly accessible places is not
recommended as this could lead to unwanted and
potentially unsafe changes to device (wiring,
configuration, etc).
It is recommended to lock the device in an enclosed
cabinet with access allowed only to approved and trained
personnel. Also, it is strongly advised to keep all the wiring
of device physically secure.
Physical protection of the device is applied via Run/Test
switch label/seal. It is intended to prevent and detect
unauthorized access.
Modbus & DDL Interface security
Any conducts critical to device functionality (DDL,
Modbus lines etc.) shall be physically protected (installed
outside public access) since they could be damaged or
tampered-with by unauthorized people, either
accidentally or for purpose.
Modbus RS-485 & DDL protocols do not support security
features. For DDL interface - only DDL devices shall be
connected to the Burner Controller DDL line.
