Input Wiring; Circuit And Wiring Specifications - Honeywell 301 Serie Mode D'emploi

• While using appropriate ESD protection, remove the PCBA from the controller and
monitor. Carefully place the PCBA in the enclosed antistatic envelope.
Mount 301 Series equipment (with displays) on vertical surfaces at approximately
•
5 ft. (1.5 m) from the floor.
• Use the product case to mark where to drill mounting holes on the mounting sur-
face. Drill the holes without the enclosure in place.
To mount monitors, refer to individual product information for mounting heights
•
based on gas being sensed.
Use the appropriate mounting hardware noted in the table above to mount the
•
product case to the mounting surface.
Remove the knockouts before reinstalling the PCBA.
•
Reinstall the PCBA.
•
• Complete wiring as shown in the Wiring diagram.

Input Wiring

Circuit and Wiring Specifications

Follow local codes when sizing power wiring:
Terminal Blocks, input, and communication: R/C (AVLV2) AWM minimum
•
300 V, 10 A, 16-22 AWG solid or stranded
Terminal blocks relays: R/C (XCFR2) minimum 300 V, 10 A, 14-22 AWG
•
stranded, 16-22 AWG solid (AVLV2) AWM
All communication wiring should be shielded.
•
Refer to Specifications table for communication line lengths.
Daisy-chain the network cable without T-taps. The 24V supply must be properly
grounded in accordance to all local electrical codes.
Dedicated Circuit-breaker and Transformer Requirements
A dedicated circuit-breaker must be used.
Ensure the transformer selected has sufficient output specifications to power the
entire system at start-up. Ensure proper polarity is followed per the instruction of
the individual device. Contact Honeywell Analytics for further assistance based on
the system design.
