CAUTION
• The Bridge 485 hardware must be installed in
accordance with national, state, and local electrical codes
and requirements.
• All work must be performed by qualified personnel.
• 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
8. DC Powered: Connect the DC power supply wire (+)
to 24VAC/VDC and (-) to COMMON.
See Figure 2.
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.

REGULATORY INFORMATION AND CERTIFICATIONS
RF Exposure Statement: This equipment complies with
FCC radiation exposure limits set forth for an uncontrolled
environment. This equipment should be installed and
operated with minimum distance of 20cm between the
radiator and your body. This transmitter must not be co-
located or operating in conjunction with any other
antenna or transmitter.
Industry Canada (IC) certifications: This digital
apparatus does not exceed the Class B limits for radio
noise emissions from digital apparatus set out in the
Radio Interference Regulations of the Canadian
Department of Communications.
Le present appareil numerique n’emet pas de bruits
radioelectriques depassant les limites applicable aux
appareils numeriques de la class B prescrites dans le
Reglement sur le brouillage radioelectrique edicte par le
