The ExCam
®
IPQ1775 is delivered with an electrical connection cable type SKDxx (Sys-
tem Kabel D
igital) and optional with an additional supply cable e.g. of the type „Ölflex®
440p
“.The maximum cable length is 100 m (depending on electromagnetic tolerance)
and can be determined individually to reflect the particular customer specifications. The
minimum cable length is 1 meter.
The ExCam
®
IPQ1775 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 connection
is either stripped to the blank Cu conductors or furnished with a plug.

Potential equalization
Figure 6.1
– ExCam IPQ1775 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 6.1). The pro-
file of the potential equalization has to reflect the national grounding instructions (min.
