Wiring a Remote Connection
You can attach any RS485-compatible cable to the RS485 connector.
The drive interface board is located in the Low Voltage Compartment and is powered by an isolated, low
voltage, 5 Vdc electrical power supply. Follow these steps to wire a remote connection:
1. Remove the four (4)
slotted head hex washer screws
securing the Wiring Compartment Cover. Set
the cover aside.
2. Remove the conduit plug and feed the RS485 cable (not supplied) through the
1/2”
NPT conduit
hole on the end of the compartment.
3. Attach the cable to the RS485 Connector to the interface board.
The 3-position DIP Switch on the interface board can be used to identify a specific MODBUS ID. A DIP
Switch ID other than zero (0) takes priority over the
Node ID
menu in the integrated UI.
Note
:
Configuring MODBUS communications assumes that you are familiar with the MODBUS RTU protocol.
The MODBUS ID settings on the DIP Switch are as follows:
DIP 1
DIP 2
DIP 3
