CAUTION
- The Control-485 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 Control-485 should not be tied to earth ground.
- Disconnect all power before installation or service.
NEEDED MATERIAL
- Screw Driver: A #2 Phillips is required to connect the cables to the terminals.
- Mounting: Mounting brackets are included. Mounting hole fits #10 screw
- Conduit: To maintain the IP rating of the unit, it must be installed with ½” cable glands or with weather-proof ½” conduit fittings at the power/signal entry points.
INSTALLATION INSTRUCTIONS
-
Select a suitable installation location for the Control485 e.g. between the BACnet thermostat and the HVAC/MAU.
-
Select between inline or adjacent installation, see Figure 1 for more details.
-
Mount the Control-485 using the brackets included.
(See last page of this install guide for mounting template). -
Open the enclosure cover.
-
Install cable glands or conduit fitting as required.
-
For AC powered: Connect the AC power wires (e.g. from the HVAC 24VAC transformer) to wire terminals COMMON and 24VAC/DC maintaining the correct polarity. See Figure 2
-
For DC Powered: Connect the DC power supply wire (+) to 24VAC/VDC and (-) to COMMON. See Figure 3.
-
If the Control-485 is being connected inline with the BACnet thermostat, connect the thermostat power wires to the same Control-485 terminals COM/GND and 24VAC/DC. See Figure 2
-
RS-485/BACnet serial connections: Connect the Control-485 screw terminal D+ to MS/TP+ on the BACnet thermostat, 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 4.
-
RS-422 serial connections: For serially controlled devices using the RS-422 standard, connect the Control-485 screw terminal RD- to the controlled device terminal TD-, RD+ to TD+, TD+ to RD+, TDto RD- and GND to GND respectively. See Figure 5.
-
Ensure all control lines are reattached to the thermostat.
