5.2.4 Earth Ground and Power
The LC-202P panel requires 12 VDC power at 750 mA. You must make a quality earth ground
connection to the controller prior to connecting the DC power lines. The earth ground provides
protection for the controller and ensures the best possible operating conditions. Possible sources for
earth ground are a ground rod, a cold water pipe, a steel building frame, the electrical system
ground at the breaker/fuse box, or the telephone system ground. Make the earth ground and power
connections per the information in Table 5 and Figure 8.

5.3 LC-208 Wiring Connections
The connections between the individual LC-200P/ SB-200 controllers in the LC-208 Elevator
Control panel are already wired. All user connections are brought out to three terminal strips.
• one strip on the left side of the enclosure for all Floor Control Relay connections
• one strip on the bottom-right of the enclosure for the controller power, the controller network
daisy-chain input, and the proximity reader daisy-chain input connections
• one strip on the bottom-left of the enclosure for the controller network daisy-chain output and
the proximity reader daisy-chain output connections
Figure 9 on page 15 provides a diagram of these terminal strip connections.
