ETX-1630x Power Requirements

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

Power Entry Panel

The power entry panel (PEP) is the RMX-10140-50Y2P.

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.
Note Ensure the system is positioned to allow you to easily disconnect power.
Table 22. Input Voltage Range
Overvoltage category II
Branch circuit rating 63 A
Voltage rating

ETX-16301: 100 V/173 V to 240 V/415 V, 3P+N+PE, 3Φ

ETX-16309: 230 V/400 V, 3P+N+PE, 3Φ
Frequency 50 Hz or 60 Hz
Current rating 50 A

The overall power consumption is 30 kW for the RMX-10140-50Y2P.

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-1630x accounts for 9 kW of this rating.
Note The product has been tested for power supply voltage fluctuations of ±10%.
Table 23. Input Power Supply Wiring
Component RMX-10140-50Y2P
Hardwired input protective enclosure screws

Tool: 3 mm hex driver

Torque: 1.3 N m (11.5 lb · in.)
Earth termination mechanical lug

Tool: 3/16 hex driver

Torque: 5.1 N · m (45 lb · in.)

Wire gauge: 14 AWG to 2/0 AWG

Wire strip length: 15.7 mm (0.6 in.)
M6 screw thread input terminal block

Tool: #2 Phillips driver

Torque: 2.5 N m to 3.0 N m (22.1 in. lb. to 26.6 in lb.)

Wire gauge: 14 AWG to 2 AWG

Wire strip length: 14.0 mm (0.6 in.)
Cable grommet

Part number: Heyco M4860

Cable bundle diameter: 22.0 mm to 32.0 mm (0.9 in. to 1.2 in.)

For the input power cable, NI recommends copper wire at least 10 mm2 (8 AWG) minimum; installation of the ETX-1630x to the facilities must be made per the local electrical code requirement, and a qualified electrical contractor should make the installation.

Caution EMO_MEASURE removes power from the main instruments and interface. The AUX C13 and RCU outlets on the PEP remain powered, but the ETX-1630x does not use those outlets to power any internal equipment. Activating EMO_MEASURE does not put the rack into a service safe state. To completely interrupt power to the rack, disconnect the AC power cable.
Attention EMO_MEASURE coupe l'alimentation des instruments principaux et de l'interface. Les prises AUX C13 et RCU du PEP restent sous tension, mais l'ETX-1630x ne les utilise pas pour alimenter un équipement interne. L'activation d'EMO_MEASURE ne met pas le rack dans un état sécurisé pour l'entretien. Pour interrompre complètement l'alimentation du rack, déconnecter le câble d'alimentation CA.
