• The common signal from the Bridge 485 hardware should not be tied to earth ground.
• Disconnect all power before installation or service.

INCLUDED MATERIAL

• 2 Cable glands
• 1 Hole plug
• Mounting brackets

NEEDED MATERIAL

• Screw Driver: A #2 Phillips is required to connect the cables to the terminals.
• Mounting Screws: Mounting bracket holes fit #10 screws
• Conduit: To maintain the 4X rating of the enclosure, it must be installed with the 4X ½” cable glands supplied or with minimum 4X liquid-tight ½” conduit fittings, not supplied, at the power/signal entry points.

INSTALLATION INSTRUCTIONS

1. Select a suitable installation location for the Bridge 485 hardware with good line-of-sight to other nodes and near the connected device that utilizes the MODBUS RTU protocol over a RS485 serial connection.

2. Mount the Bridge 485 hardware using the brackets included.

3. Open the enclosure cover.

4. Install ½” cable gland(s) supplied and torque nuts to 60 in-lbs; or use liquid-tight conduit fittings as required.

5. If only one cable entry is used, plug the unused hole with the liquid-tight plug supplied.

6. To maintain the IP rating, jacketed cable wires are recommended with cable diameter of 0.21” – 0.33”.
   Torque sealing cable glands to 40-55 in-lbs, depending on the cable diameter and jacket hardness.

7. AC powered: Connect the AC power wires to wire terminals COMMON and 24VAC/DC maintaining the correct polarity. See Figure 1
   Figure 1. 24VAC connections
   

8. DC Powered: Connect the DC power supply wire (+) to 24VAC/VDC and (-) to COMMON. See Figure 2.
   Figure 2. 24VDC connections
   

9. RS-485/MODBUS serial connections: Connect the Bridge 485 screw terminal D+ to MS/TP+ on the devices that utilize the MODBUS RTU protocol over a RS485 serial connection, D- to MS/TP- and GND to GND; or connect to D+ to D+, D- to D- and GND to GND on any other RS-485 serially controlled devices. See Figure 3.
