Primary power supply requirements
Notice
・ Always take care to comply with your national regulations for power supply
installations. If a drainage pit is not located near the chamber, drain in a container.
・ External power supply cables shall be of approved type and in compliance
with IEC/EN60227 or IEC/EN60245 or any other applicable national regulation.

Prepare the power supply and power cable satisfying the following requirements.
