Question:
What is the purpose of the external grounding of an APC Rack PDU or ATS?

Product:
APC Rack Power Distribution Units and Rack Automatic Transfer Switches

Environment:
APC Rack Power Distribution Units and Rack Automatic Transfer Switches

Solution:

APC by Schneider Electric rack power distribution units (PDU) and rack automatic transfer switches (ATS) will have an external grounding provision.
Please note that high leakage current from attached loads is possible. Please contact the manufacturer of the equipment attached to know the equivalent total leakage current of all your devices. If total leakage current of all attached load exceeds 3.5mA, it is highly advised to attach a ground wire from the Rack PDU or Rack ATS supplementary ground (M5 thread labelled with the ⏚ symbol) to a reliable ground in your facility. This should be done before energizing the Rack PDU or the Rack ATS and installation for this external grounding must be done by a qualified personnel / electrician.
Additionally, you may refer to the attached safety documents for our Rack PDU and Rack ATS or you may contact our Tech Support team at 800-800-4272 or chat with us at APC by Schneider Electric for more information.
