Wiring
For detailed information on configuring and wiring an MS/TP Bus, System Bus, and Sensor Bus, refer to the
Verasys® BACnet® MS/TP
Communications Bus Technical Bulletin (LIT-12012362).
Verasys Application Controller Terminal Blocks and Bus Ports
See
Figure 11 for terminal block, spade location, and bus port locations on the LC-VAC300x-0 controller. Use the
following guidelines when wiring a controller.
Input and Output Terminal Blocks
On most field controller models, all of the input terminal blocks or spade terminals are mounted on the bottom of the
controller and the output terminal blocks and spade terminals are mounted on the top of the controller. See Table 5
for more information about I/O terminal functions, requirements, and ratings.
Risk of Electric Shock.
Disconnect power from the controller before making any adjustments. Do not touch any part of the printed circuit
board while power is applied. Failure to follow these precautions can result in personal injury or death.
Risque de décharge électrique.
Déconnecter l'alimentation du controller avant toute opération de réglage. Veiller à ne toucher aucune partie du
circuit imprimé lorsque celui-ci est sous tension. Le non-respect de ces précautions peut provoquer des blessures
graves, voire mortelles.
Risk of Electric Shock.
Disconnect or isolate all power supplies before making electrical connections. More than one disconnection or
isolation may be required to completely de-energize equipment. Contact with components carrying hazardous
voltage can cause electric shock and may result in severe personal injury or death.
Risque de décharge électrique.
Débrancher ou isoler toute alimentation avant de réaliser un branchement électrique. Plusieurs isolations et
débranchements sont peut-être nécessaires pour -couper entièrement l'alimentation de l'équipement. Tout contact
avec des composants conducteurs de tensions dangereuses risque d'entraîner une décharge électrique et de
provoquer des blessures graves, voire mortelles.
IMPORTANT:
Do not exceed the controller electrical ratings. Exceeding controller electrical ratings can result
in permanent damage to the controller and void any warranty.
IMPORTANT:
Use copper conductors with a rating of at least 75°C (167°F). Make all wiring in accordance with
local, national, and regional regulations.
IMPORTANT:
Electrostatic discharge can damage controller components. Use proper electrostatic discharge
precautions during installation, setup, and servicing to avoid damaging the controller.
