5.1

Installation of a MIC440 Camera

This chapter provides an overview for the installation of a MIC440 camera.

Caution!

The MIC440 camera is designed for use with flammable gases and vapors covered by
apparatus groups IIA, IIB and IIC and with temperature class T6. The product is certified for
use within the ambient temperature range of -20 °C to +60 ºC and must not be used outside
this range.

While a MIC440 camera is certified for installation in a hazardous area, its power supply unit
(PSU) is not. The PSU itself can be installed in either a non-hazardous area or in a hazardous
area. If installed in a hazardous area, the PSU must be placed inside a certified enclosure that
is certified for use in hazardous areas.

Warning!

ROUTING OF EXTERNAL WIRING MUST BE DONE THROUGH A PERMANENTLY EARTHED
METAL CONDUIT.

Mounting the Conduit Gland and Cable

The MIC composite cable (8 mm) required to connect the MIC440 to its power supply consists
of two pairs (24AWG) plus 4 cores of (22 AWG), 2 cores of (24 AWG), and one coax core for
the video signal to a maximum distance of 25 m.

Warning!

Bosch recommends connecting the cable to the unit before taking the unit for mounting on­site.

To mount the conduit gland and cable, follow these steps:

1. Remove the 4 x M8 Hexagon bolts holding the conduit adapter (DCA) to the MIC440 unit.

Remove the DCA.

2. Fit the unterminated ends of the composite cable through the 20 mm threaded gland hole

in the DCA. Allow approximately 100 mm of free cable on the inside to connect to the 12-

way cable connector.

3. Screw the Exd conduit gland into the DCA, maintaining approximately 100 mm of cable

on the inside of the DCA to enable the cable connector to be inserted freely into the MIC

unit base connector.

4. Connect the 12-way cable connector into the matching connector in the base of the MIC

unit.

5. Ensure that the connector is fitted properly in the camera’s integral plug. Turn the socket

thread ring approximately two and a half turns to fasten the two halves of the connectors

together properly.

6. Bolt the DCA onto the MIC440 unit; tighten the 4 x M8 hexagon bolts.

7. Ensure that there are no trapped cables.

8. Ensure that there is some slack cable in the DCA, then tighten and seal the Exd barrier

gland per the instructions included with the gland. The unit with the cable tail is now

ready for on-site installation.
