2.13.3.1 Electrical Grounding Requirements
The appliance must be grounded properly for efficient operation and safety. United States electrical
codes require you to install the BT1 Security Appliance in accordance with NFPA 70 and local and
regional building codes. Canadian electrical codes require you to install the equipment in
accordance with Canadian Standards Association.
Additionally, ensure all PDUs are listed or certified grounding devices.
Ground leakage currents associated with multiple appliances connected to a single power source
can be high. It is recommended that PDUs are either permanently wired to the building’s branch
circuit or use a nondetachable cord that is wired to a NEMA locking plug. See image below.
