Connections of all power cables, control cables, and ground cables must
comply with the local electrical code, and the cable specifications should
comply with the local cabling specifications.
For details about the maximum current, see the equipment nameplate.
Ensure that the voltage and frequency of the primary power supply meet the
requirements.
Only trained and qualified personnel are allowed to connect cables.
Before connecting cables, use a multimeter to measure the input voltage and
ensure that the power supply is off.
Ensure that all smart cooling products are safely grounded before powering
them on.
Keep cables away from the fan, and so on (if unavoidable, take protective
measures), and ensure that cables are securely connected.
When laying out cables, ensure that the power and signal cables are reliably
separated and that the strong- and weak-current cables are bound separately.
