How to Install The BACnet Option Installation of the Option Items required to install a serial communication bus option in the adjustable frequency drive: - The serial communication bus option - Serial communication bus option adaptor frame for the adjustable frequency drive. This frame is deeper than the standard frame, to allow space for the serial communication bus option beneath. - Cable holders TR200 BACnet 3-1

How to Install Instructions: - Remove the keypad panel from the adjustable frequency drive. - Remove the frame located beneath and discard. - Push the option into place. Two positions are possible, with cable terminal facing either up or down. The cable up position is often most suitable when several adjustable frequency drives are installed side by side in a rack, as this position permits shorter cable lengths. - Push the serial communication bus option adaptor frame for the adjustable frequenc

How to Install Cable Routing The BACnet communication cable must be kept away from motor and brake resistor cables to avoid coupling of high frequency noise from one cable to the other. Normally a distance of 7.9 in (200 mm) is sufficient, but maintaining the greatest possible distance between cables is generally recommended, especially where cables run in parallel over long distances. When crossing is unavoidable, the BACnet cable must cross motor and brake resistor cables at an angle of 90 deg
