3-2 System Preparation
3.2 Connecting Power Cord & Protective
Grounding
3.2.1 Connecting Power
The power system must meet the following requirements:
Voltage:220-240V
Power supply frequency: 50/60Hz
Power consumption: greater than 800VA
The connection method is described as follows:
1. Push the retaining clamp upward, and insert the power plug into the receptacle, as shown in
the figure below.
2. Pull the retaining clamp downward to lock the power cord, as shown in the figure below.
3. Plug the other end power plug into an appropriate outlet. The grounding terminal should be
connected with a power grounding cable to ensure that protective grounding works normally.
Make sure to allow sufficient slack in the cable so that the plug will not be pulled out of
the receptacle if the system is moved slightly. If the plug is pulled out accidentally, data
may be lost.
