    IMPORTANT: When working with circuit board connecting wires to the terminal block, confirm that the components, Bard recommends the use of fuse in each of the four fuse holders is in the proper an anti-static wrist strap to prevent static position (active) as shown in Figure 2.

  • Page 7: Supply Wiring

    Supply Wiring The LC6000 controller is powered by 120, 208 or 240 volts from the shelter. Field-supplied supply wiring should be minimum 16 gauge, maximum 14 gauge (see Figure 3). A reliable earth ground must be connected in addition to any grounding from conduit. Grounding bolts and nuts are included with the controller for this purpose; a 2 hole grounding lug must be field supplied.

  • Page 8: Installing Remote Indoor Temperature/Humidity Sensor(S)

    Installing Remote Indoor Temperature/Humidity Sensor(s) One remote indoor temperature/humidity sensor and 35' of 18 gauge 5-conductor shielded cable is included with the controller. This sensor must be installed for proper operation. Mount the temperature/humidity sensor in a location least likely to be affected by open doors, rack-mounted fans, radiant heat sources, etc. Locating the sensor between both return grilles is often the best location, but every installation is unique.

  • Page 9: Figure 1 Figure

    For proper operation, the remote indoor temperature/humidity sensor (and any additional sensors) must be configured properly with the controller as shown in Step 2 on page 8. An additional remote indoor temperature- only sensor can be purchased and installed in Zone 1. If the site in which the LC6000 controller will be used has more than one zone (maximum three zones per LC6000), additional remote temperature/humidity sensors (one per zone) will need to be purchased and installed in the additional zones.
