User’s Guide GLI 2000 5BNC GLI 2000 2BNC Passive Ground Loop Inhibitors 68-811-01 Rev.
Introduction The GLI 2000 5BNC and GLI 2000 2BNC are heavy-duty, passive ground loop inhibitors. Ground loop inhibitors eliminate hum bars (as shown below) and common mode noise caused by improper video equipment grounding. Ground loop problems can be caused by using AC power sources with different ground levels or by plugging high-current equipment into the same power source as video equipment.
Installation The GLIs can be mounted on a standard universal 2U rack shelf. Rack mounting Mount the GLIs on a standard universal 2U rack shelf (Extron part #60-032-01). The GLI 2000 5BNC mounts in one of four locations at the front or the rear of the rack. The GLI 2000 2BNC mounts in one of eight locations at the front or rear of the rack. 1. Remove rubber feet if they were previously installed on the bottom of the GLI. 2.
