MIC440 Explosion Protected CCTV Camera System| Installation and Operation Manual EN | 13
Bosch Security Systems Issue 6
Earthing of the MIC440 Camera
. The camera module & housing are electrically isolated so the housing
should be safety earthed regardless. The safety earth should be a bonding
connection to the cameras outside case for example one of the securing
bolts.
2. The camera should be earthed at one point only to prevent earth loops &
thus hum bars showing on the control room monitor.
3. If the system is copper throughout & the camera pictures are fed back to
the control room coaxial copper cable, then the camera should be earthed
at the video termination point in the control room & nowhere else. In this
case the PCB “Earth Link” should be broken.
4. If the video is transmitted back to the control room via some non electrical
connecting medium, e.g. fibre optic, radio or microwave link, then the
camera should be earthed at the transmitter point in the psu. The PSU
“Earth Link” may be used for this purpose.
5. If dual earthing is unavoidable then a video isolation transformer should be
fitted between the two earths.
Lightning Protection
If the camera is fitted in a highly exposed place then consideration should be given
to lightning protection. A good earth bonding connection to the case itself will
provide protection against damage from secondary strikes.
Where there is a risk of a primary strike hitting the camera housing directly, it is
recommended that a separate lightning conductor be fitted within 0.5m of the
camera and at least .5m higher than the camera.
The construction of the housing itself is very capable of coping with secondary
strikes and no damage to the internal electronics or camera should result if correct
lightning protection is applied.
Maintenance
The unit contains no maintainable parts and in the event of failure should be
removed from site for repair.
Maintenance and repair of this equipment shall only be carried out by suitably
trained personnel in accordance with the applicable code of practice (e.g.
EN60097- 9)
To maintain the validity of the certification only components supplied by Bosch
Security Systems shall be used.
On Site Inspection
It is recommended that the equipment be inspected on site every six months to
check mounting bolts for tightness, security and any signs of physical damage.
Inspection of this equipment shall only be carried out by suitably trained personnel
in accordance with the applicable code of practice (e.g. EN60097- 7)

PCB Earth Link
The PCB has one link option next to HD to allow the power supply to be set up for
different earthing schemes: The Earth Link should be broken if there is a separate
connection between video screen and earth. Usually occurs on copper connected
systems where all the copper video coaxes are taken back to the control room to
be connected to a central earth point. If fibre optics or other indirect connections
are used to get data and video to and from the control room then the earth link
should be left intact provided it is the only camera end earth reference point.
WARNING: Electrical Danger: Ensure all power is disconnected
before opening or working upon any Power Supply Unit.
Installation must be carried out by suitably qualified persons & all
local safety regulations should be followed.

CHAPTER 4
Configuring the MIC440 Camera
Connecting the MIC440 to the PC
The MIC can be connected to a PC’s serial port via a RS232/RS422 adaptor unit;
this will generally be assigned to Comm Port .
Suitable serial port adaptor units are the Greenwich RS232/RS422 adaptor unit
(Farnell 778-758, RS No: 20 -758), the KK systems K2-ADE RS232 to RS485/422
adaptor or the MIC-USB485CVTR (485 to USB Converter) for PC’s without a serial
port.
Connecting the Greenwich Adaptor
To connect the Greenwich serial adaptor to the PC you will also need a 9 pin D
female to 25 pin D male RS232 compatible adaptor cable. A suitable cable is
Farnell 960-573 or RS Part No: 202-644. The adaptor should be set to DCE mode
and the power supply connected.
Connections from the Greenwich adaptor to the power supply are shown below
