NOTE:
• When two or more expansion units are connected, both cables in ENC
unit #0 and ENC unit #1 should be connected to the high-density
expansion unit.
• If it is necessary to bend an ENC cable to connect it, keep the bend
radius as large as practical, and not less than 30 mm. This prevents
excessive stress on the cable and the connector.
• The IN and OUT connectors on the ENC units have blue and green
labels, respectively.
Complete the following steps to install the ENC cables on a high-density
expansion unit. Note that the ENC cable does not plug directly into the ENC
unit in the high-density expansion unit.
1. Install the ENC cable in the high-density expansion unit cable holder, as
shown in Figure 5-37.
2. Remove the rubber cap from the ENC connector on the control unit.
3. Connect the ENC cable to the control unit.
4. Route the cable through the cable routing bars to the appropriate high-
density expansion unit. See
installation chapter in the maintenance manual.
