Installation
Main/secondary network with user terminals, remote display and external driver.
The main controller, connected to the supervisor network, coordinates the operation of up to 9 secondary controllers connected
to the network via RS485 Fieldbus. Each controller can be connected to a remote display or an external driver.
Caution: for connection to a main/secondary network, the local subnet must be wired according to the following logic:
• main BMS (J4): connected to the supervisory system;
• main Fieldbus (J5): connected to the BMS (J4) on the secondary devices.
