MIC Series 500 Camera MIC 500 Series Camera Quick Start Guide en 5

The MIC 500 Series camera has a security attachment point for attaching to a safety chain (not supplied), which in turn should be attached to a secure part of the structure during installation or removal.

WARNING!

Use caution when installing the MIC 500 Series camera. Follow common sense precautions such as fitting a safety chain.

1.2	Safety Earthing of the MIC 500 Series Camera
		The electronics and housing of the MIC 500 Series camera are electrically isolated; however,
		the housing should be safety earthed regardless. This safety earth should be a bonding
		connection, such as one of the securing bolts, to the outside case of the camera. The camera
		should be earthed at one point only to prevent earth loops and thus hum bars appearing on
		the camera picture in the control room.
		Shielded Composite Cable Connections
		Note: all connections must be made.
