ETX-1640x Power Requirements

Provide AC power connection to facility power source and connection to protective earth ground.

The power entry panel (PEP) used in your system depends on your High-Power Production Test Base System model. Refer to ETX-1640x System PEP Ratings for more information about the PEP ratings for your specific model.

For the input power cable, NI recommends copper wire at least 10 mm2 (8 AWG) minimum. Installation of the ETX-1640x to the facilities must be made per the local electrical code requirement, and a qualified electrical contractor should make the installation.

Note The overall power consumption is the maximum power dissipation with all equipment in the rack at the maximum allowable power. The actual value varies depending on the system use. The high-power supply installed in the ETX-1640x accounts for 9 kW of this rating.
Note The product has been tested for power supply voltage fluctuations of ±10%.
Note Ensure the system is positioned to allow you to easily disconnect power.
Caution To completely interrupt power to a three phase system, you must switch off the main breaker on the power entry panel. Position equipment so that it is easy to access the main breaker.
Attention Pour interrompre complètement l'alimentation d'un système triphasé, vous devez éteindre le disjoncteur principal sur le panneau d'entrée d'alimentation. Positionner l'équipement de sorte qu'il soit facile d'accéder au disjoncteur principal.
