Figure 8: Transformer grounding
CAUTION
Risk of Property Damage:
Do not apply power to the system before checking all wiring connections. Improper wiring of this
terminal may cause a short circuit across the 24 VAC power supply. A short circuit may result in a
tripped circuit breaker or blown fuse. If using a transformer with a built-in fuse, the transformer may
need to be replaced.
ATTENTION
Risque de dommages matériels:
Ne mettez pas l’appareil sous tension avant d’avoir vérifié toutes les connexions du câblage. Le câblage
inadéquat de cette borne peut causer un court-circuit sur l’alimentation électrique de 24 V c. Un court-
circuit peut causer le déclenchement du disjoncteur ou le grillage d’un fusible. Si vous utilisez un
transformateur avec un fusible intégré, vous pourriez devoir remplacer le transformateur.
To wire the CVM03050 controller, complete the following steps:
1. Terminate wiring according to the appropriate figure in Termination diagrams.
2. Wire network sensors and other devices to the SA Bus.
3. Ensure that the CVM03050 is assigned a device address. Set the device address using the
rotary switches at the top of the controller. See Setting the device address.
4. Connect the CVM controller to 24 VAC, Class 2 power.
Note: If you are using the CVM03050 controller with the Wireless Field Bus System, refer to
the WNC1800/FX-ZFR182x Pro Series Wireless Field Bus System Bulletin (LIT-12012378) or the FX-ZFR
