GENERAL INFORMATION

1. Each Convia ® Enabled Walkerflex ® System connector contains a color coded key that indicates rating, conductor location and orientation. Only like colored keys can be mated. See Key Configuration and Color Chart on page 11 for available options. Each key is comprised of one or more configurations.

2. Disconnect power from source prior to wiring any Walkerflex component into the building’s electrical power system.

3. Installer to determine the maximum power cable length based on wire gauge and circuit load.

4. Installer to ensure adequate overload protection based on the system key, rating and circuit load.

5. Refer to appropriate Wiring Diagram and System Key

Configuration Conductor Location Chart for field connections of Cat. Nos. CNWC/CLWC (Wire Connector) and

CNCW/CLCW (Cable Whips). Refer to wiring diagram supplied with CNDU/CLDU (Distribution Unit) for field termination.

6. Securing and Supporting of Cables and Components: Refer to NEC Article 604, Manufacturing Wiring Systems and any local codes.

7. Cap all unused connector openings with Cat. No. CAP3456

(for 3 through 6 wire system) or Cat. No. CAP810 (for 8 and

10 wire system).

8. All Convia Enabled accessories are available in a 3-6 wire and 8-10 wire system and are rated 20A, 120V.

9. 277V Convia Enabled Walkerflex components are only available in 3-6 wire configurations.

10. The Convia Enabled Walkerflex system is compatible with the standard Walkerflex system of the same configuration and key.

CONVIA ENABLE WALKERFLEX SYSTEM INSTALLATION

CNDU and CLDU Module & Flex Cables:

The CNDU and CLDU (CLDU is available for 3-6 wire configurations only) module is the main power source and interface to the Convia Enabled Walkerflex System. It is to be fed from a distribution panel outfitted with appropriate circuit breakers to protect wiring.

CONVIA ENABLE WALKERFLEX SYSTEM INSTALLATION (continued)

Network Hubs

The Network Hub module makes up the backbone or Main Bus of the network. Multiple

Network Hubs can be configured to increase the size of the network or to increase the number of available ports in an installation location. Up to 50

Network Hubs can be connected on a single network with a patch cable length of up to 2000 feet. Refer to the ConviaNet Design Guide for more information.

Step 1: Mount Network Hub securely using appropriate screws and anchors.
