Site Preparation

You must follow all safety and site requirements and instructions in this manual to properly set up, configure, and use the Battery Test System.

Ensure the facility meets the following environmental, physical, and interface requirements before the system arrives.

Power Connection

Power connections must meet the power requirements listed in the BTS-16101 Battery Test System Measurement Rack Safety, Environmental, and Regulatory Information document. The measurement rack contains a power entry panel (PEP) for AC MAINs and a corresponding power plug.

The system must meet the following power connection requirements:

  • AC MAINs power must be supplied to the system power plug.
  • Power cord(s) must meet the following criteria:
    • Cable/wires must be insulated for the highest voltage based on the input rating of the system, and properly sized for current rating.
    • Wire gauge specifications must meet or exceed requirements and in compliance with all applicable local codes and requirements.
    • Wired by a qualified electrician.

Power Recommendations

NI recommends the following the following power considerations:

  • Provide separate AC branch for the system due to the current requirements of the system.
  • Copper wire for the system drop between the AC source and system.
  • Before servicing the measurement rack, physically remove the MAINs plug from the power outlet.
Caution You must turn the main power switch on the EPO panel to the Standby position to fully disable the UPS output power.
Attention Vous devez mettre l'interrupteur d'alimentation principal du panneau d'arrêt d'urgence en position de veille pour désactiver complètement l'alimentation de sortie de l'onduleur.
Caution Verify the AC source and service conductor are sized correctly before connecting the system.
Attention Vérifiez que la source CA et la ligne de service sont correctement dimensionnées avant de connecter le système.
Caution Do not position equipment so that it is difficult to disconnect the AC power cable from the rear of the rack. To completely interrupt power to a single phase system, you must disconnect the AC power cable.
Attention Prenez soin de placer l'équipement de sorte qu'il soit facile de déconnecter le câble d'alimentation CA de l'arrière du rack. Pour interrompre complètement l'alimentation d'un système monophasé, vous devez déconnecter le câble d'alimentation CA.

Ventilation and Cooling

The measurement rack includes several features to help facilitate proper cooling, but due to instrumentation layout, third-party devices, cabling, and mass interconnect, it is important to do a thorough thermal assessment of the final system assembly.

The measurement rack includes the following features to help facilitate cooling:

  • Low-speed fan panel with six 120 mm fans capable of driving a total of 540 CFM. You can add additional airflow with a 1U rack mount fan panel that utilizes three 4 in. fans (270 CFM) for targeted areas within the rack.
  • 4U air inlet panel to facilitate airflow into the rack.

NI recommends that the air filters are properly maintained based on environmental conditions. These filters are user serviceable and replacement kits are available; refer to Battery Test System Replacement Parts for more information.

Note Do not block the top (exhaust vent) or air intake of the low-speed fan panel.

Ventilation Recommendations

NI makes the following ventilation recommendations:

  • Maintain 2U of open space directly above and below the power entry panel (PEP) to allow for proper airflow through the panel.
  • Do not add equipment to the top 1U of the rack or modify the position of the power distribution unit (PDU) located on the top of the rack. NI has validated sufficient cooling with the PDU and Ethernet switch in their pre-installed locations.

Exhaust

The exhaust air from all instruments should have an unobstructed pathway to exit the rack. Arrange instruments to provide a continuous airflow path from all instrument outlets.
