Power Cables
An AC mains power cable is not provided with the unit. Refer to the following table for the maximum current capacity
requirements for each cable conductor.
If required by local electrical codes, install a fuse or circuit breaker between the ac mains and the unit. Refer to the fol-
lowing table for current ratings.
Keep the AC mains cables as short as possible. The longer the cable, the greater the voltage loss due to cable resistance.
The cable cross-section must be suitable for the maximum input current of the instru-
ment. The ground cable must be of the same cross-section as the phase cables.
Safety agency requirements dictate that there must be a way to physically disconnect the AC mains
cable from the unit. A disconnect device, either a switch or circuit breaker must be provided in the
final installation. The disconnect device must be in close proximity to the equipment, shall be easily
accessible, and shall be marked as the disconnect device for this equipment. It must meet the input
ratings requirements listed in the following table.
