13.5.2 Planning Wiring Runs
When planning the layout of the conditioned space, consider the following:
• Good wiring practices.
• An Ethernet repeater is required for cable lengths greaterthan328ft(100m).
• A private network that only connects and manages the cooling units is required.
• Keep control and communication cables away from power cables to prevent electromagnetic interference.
• Keep cables away from noise introducing device such as machines, fluorescent lights and electronics.
• Do not bend cables to less than four times the diameter of the diameter of the cable.
• Do not deform cables when hanging or securing in bundles.
• Do not exceed 25lb (11kg) of tension when pulling cables to avoid stretching.
• Do not damage cables when securing them. Use only approve hangers, such as telephone wire/RG-6 coaxial-
