Grounding the Chassis
The chassis has a grounding lug located on the rear of the chassis. This lug uses 10-32 screws and is
surrounded by a small paint-free area, which provides metal-to-metal contact for a ground connection.
Use this connector to supplement the ground provided by the AC power cord. To do so, install a Panduit
Grounding Lug (type LCD8-10A-L) using 8AWG copper conductors to the paint-free area.
Additionally, ensure that all AC sources used to power the OS-BPS and the OmniSwitches share a
common electrical ground. The “Earth Ground” for all AC sources must be a solid common ground that
does not have any electrical potential (voltage) between them.
Refer to the rear chassis views on

for location details.
