Coax grounding:

– Ground the cable system if connecting an outside cable

system to the unit.

– Connect outdoor equipment to the unit's inputs only after

this unit has had its grounding plug connected to a

grounded outlet or its ground terminal is properly

connected to a ground source.

– Disconnect the unit's input connectors from outdoor

equipment before disconnecting the grounding plug or

grounding terminal.

– Follow proper safety precautions such as grounding for

any outdoor device connected to this unit.

CAUTION!

This product has been tested according to standard CIE/IEC

62471:2006 “Photobiological safety of lamps and lamp

systems” and found to meet Risk Group 2 for exposure limit

4.3.7 “Infrared radiation hazard exposure limits for the eye.”

For other hazard exposure limits, the product was found to be

exempt. Risk Group 2 is characterized in the standard as

“products generally do not pose a realistic optical hazard if

aversion responses limit the exposure duration or where

lengthy exposures are unrealistic.” Since there is no aversion

response for IR, avoid eye exposure. Risk Group 2 sources do

not pose an infrared radiation hazard for the eye within 10 s at

distances beyond 200 mm or 8 inches. The Exposure Hazard

Value for the product (ratio of the Exposure level to the

Exposure limit) is up to 10 at a test distance of 200 mm (8

inches). The Hazard Distance (distance beyond which the

product falls into the exempt/safe group) is at most 640 mm

(25 inches). Note that typical use cases are well beyond the

Hazard Distance.When servicing the unit, physically disconnect

the power supply to avoid possible IR exposure to the eyes. If

physical disconnection is not possible, use appropriate

shielding to block the LED panel or use eye protection with a

transmission of 10% or less at a wavelength of 850 nm.
