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 frequency drive into place.

-Remove the plug for the Drive port and connect the plug that is connected to the BACnet option

-Replace the keypad panel.

-Attach cable.

-Fasten the cable in place using cable holders. The adjustable frequency drive top surface has pre-drilled threaded holes for attaching the cable holders to the unit.

Cabling

Cable lengths and number of nodes

The maximum cable length allowable in one segment is dependent on the transmission speed. The total cable length includes drop cables if any. A drop cable is the connection from the main bus cable to each node. If a T- connection is used, permissible cable length and maximum number of nodes/drives are 1, 2, 3 and 4 bus segments.

Drop cable connection (i.e., T-connection) beyond the cable lengths indicated is not recommended, due to the increased risk of reflection occurring. Instead, Trane recommends direct connection of the adjustable frequency drive.

Note that a repeater is a node in both of the two segments it connects. The number of adjustable frequency drives is based on a single master system. If there are two or more masters (e.g., PC tools, routers), the number of adjustable frequency drives must be reduced correspondingly.
