Installing the E2 Controller
Mount the E2 Controller in a location suitable for Type 1
(NEMA1) equipment.
1. Connect the I/O or MODBUS Network to one or all of
the E2 RS485 I/O or MODBUS Network ports. (A
maximum of 31 devices can be wired to each I/O or
MODBUS Network port.)
2. If the E2 is the beginning of all RS-485 I/O or MODBUS
Networks, set all three jumpers to the UP position. For
MODBUS, set the jumpers in the top-most position
(MOD). For I/O Net, set the jumpers in the middle
position (I/O). For no termination, set the jumpers to the
DOWN position (NO).
3. Connect earth ground to one of the two ground
terminals provided. Use 12 AWG (preferred) or 14 AWG
wire and keep as short as possible (less than 12 inches
preferred).
4. Connect 24VAC Class 2 to the power terminals.
5. Flip the power switch to the ON position. When 24VAC
has been applied to the board, the green LED will
illuminate.
