The ExCam
®
IPM1145-(L) Series is delivered with the electrical connection cable type
SKD02-T suitable for the hazardous area. Optionally, the camera can dispose of a power
cable (standard is a type
„Ölflex® 440P“).The maximum cable length is 100 m (depend-
ing on electromagnetic tolerance) and can be determined individually to reflect the partic-
ular customer specifications. The minimum cable length is 1 meter.
Die ExCam
®
IPM1145-(L) is manufactured with a pigtail reflecting the desired cable
length. Any electro-technical work
inside the camera’s flameproof enclosure done by the
user is prohibited.
Depending on the model option, the ending of the camera’s cable con-
nection is either stripped to the blank Cu conductors or furnished with a plug.

Potential equalization
Figure 5.1
– ExCam IPM1145-(L) potential equalization
The potential equalization / earthing of the camera housing is mandatory in order to avoid
electrostatic charging and hence spark generation. The screw terminal at the lower right
hand side of the housing’s rear side is intended for that purpose (q.v. figure 5.1). The pro-
file of the potential equalization has to reflect the national grounding instructions (min.
