communicate via the onboard EdgeSC supervisory controller with a Building Automation System
(BAS) or Building Management System (BMS) using either BACnet® or Modbus® protocols.
The EdgeSC is designed with integrated communication as one of its main features. In addition to
the I/Os, it connects to a BMS and the cloud using two primary methods:
1. Open the rear, low-voltage electrical panel on the right side of Element per Figure 24.
2. Connect as required to the
building’s internet connection to the top RJ45 ports, ENET 1.
The other RJ45 port, ENET 2, is used for BAS connections.
3. To the right of the ports is a 3-pole terminal block for an RS485 connection. Connect to the
open pole on the left for BAS RS485 +, to the middle for BAS RS485 -, and to the right for
BAS RS485 Ground.
NOTE
The BAS chain may only have one shield connection in order to avoid a ground loop. If that is
Element, connect at the green ground screw below the RS485 terminal block. Else connect it
elsewhere among BAS units.
