The Terminal ring size should correspond to M4. The cable should be attached to the unit with the provided screws and a torque of 1.3 to 1.8 N-m.
Grounding
WARNING
This equipment must be grounded. Never operate it without a suitably installed ground conductor. If you are uncertain whether suitable grounding is available, contact the appropriate electrical inspection authority or an electrician.
The NSCP AC devices must be appropriately electrically grounded. The NSCP appliance offers on the left-hand side of the appliance is the ground/earth screw for this purpose.
Device Installation
NSCP devices are designed to be installed into a data center rack. They must be installed into racks with appropriate cable management solutions. Racks offer various cable management options, and users can implement their specific cable management guidelines, such as side cable management options.
Read all the safety guidelines (WARNING and SAFETY Section) before proceeding with the connections to protect yourself and your Nodegrid Serial Console Plus.
The NSCP device cable management can be done using cable management solutions provided by the rack manufacturer and directly integrated into the rack, or device cable management can be performed by adding cable management solutions like lacing bars.
This guide will only outline a validated installation into a rack with a built-in cable management solution. The solution must provide cable management options on the left side of the unit. Additional cable management options can be provided as long as they do not impede the cable management on the left.
IMPORTANT
Appropriate cable management is an integral part of correctly using and installing the provided AC equipment. There is no “one“ proper way of performing cable management; therefore, some judgment must be made. At the core, cable management must fully support the following functions.
avoid any trip hazards, accidental and through negligence
avoid the accidental disconnection of connections or cables
provide a safe work environment
Installation
Users may decide to implement their own guidelines, but the following general requirements must be observed for the installation of NSCP AC:
Observe the minimum bending radius for the used power cable for non-motion.
For example, the cable with an 8 mm diameter should have a typical non-moving minimum bending radius of 48 mm. The cable should be attached to the unit with the provided screws and a torque of 1.3 to 1.8 N-m.
WARNING
Check the cable specification before the installation for cable-specific details.
Affix the AC power cables to an appropriate mounting facility provided by the rack.
AC power cables should be guided to the left side and console cables to the right, separating power and other passive cabling clearly.
