3-2 System Preparation
2. Push the retaining clamp downward, and lock the power cord, as shown in the figure
below.
3. Plug the other end power plug into an appropriate power socket. The grounding
terminal should be connected with a power grounding cable to ensure that protective
grounding works normally.
NOTE: Make sure to allow sufficient slack in the cable so that the plug will not be pulled
out from the socket even if the system is moved slightly. If the plug is pulled out
accidentally, data may be lost.
WARNING:
1. DO NOT connect the three-wire cable of the system with
a two-wire plug without protective grounding; otherwise,
electric shock may result.
