Specifications

BACnet Communications

The driver communicates with another module/component through the EIA-485 BACnet protocol.

• Termination Resistors
  Matched terminating resistors are required at each end of a segmented bus wired across (+) and (-).
  Use matched precision resistors rated 1/4W. ±5%. 80 -130 Ohms. Ideally, the value of the terminating resistors should match the rated characteristic impedance of the installed cable. For example, if the installed EIA-485 BACnet cable has a listed characteristic impedance of 120 Ohm, install 120 Ohm matched precision resistors.
• Shield Terminating
  Following proper EIA-485 BACnet cabling shield grounding procedures is important to minimize the risk of communication problems and equipment damage caused by capacitive coupling.
  Capacitive coupling is caused by placing EIA-485 BAC­net cabling close to lines carrying higher voltage. The shield should be grounded on only one end of the seg­ment (typically the router end). Tie the shield by using the SHLD on the driver.

Sylk communication
The driver can be connected with one and only one wall module through Syllabus.
The Sylk terminals are con­nected with two-core wire. The maximum connection length is 60 meters.
LED indications
The driver has one 2-color LED to indicate device state as following:

Terminal Wiring

Dimensions (mm)

Before installation

Review the installation guide and datasheet before in­stalling the driver.

• Make sure the devices are installed and used in physical security places and networks, only the author­ized person could operate the devices and access the network.
• Make sure the security of installation and mainte­nance for the network and upper plant controllers, the detailed information could refer to the plant con­trollers’ instructions.
• Make sure the devices are all in the isolated internal

Mounting

The driver enclosure is constructed of a plastic base plate and two DIN rail hooks. The cover does not need to be removed from the base plate for either mounting or wiring.
The driver can be mounted in any orientation. Ventilation openings are designed into the cover to allow proper heat dissipation, regardless of the mounting orientation.
The terminal screws must be locked tightly after wiring.
NOTE: The driver must be mounted in a position that allows clearance for wiring, servicing, and removal.
The driver mounts to DIN rail (standard EN50022; 7.5mm x 35mm).

1. Holding the driver with its bottom tilted in towards the DIN rail, hook the two bottom tabs on the back of the driver onto the bottom of the DIN rail.
2. Pull up and rotate the driver to make sure the two-tops snap of the driver onto the DIN rail.

Fuse exchange

Must cut off the power before replacing.
The driver has a built-in fuse, and the cover of the control module should be removed when replacing.
Please wear insulating gloves during the replacement process to prevent damage to the circuit board.
