In contrast to the wiring of power rails there should always be a feed point or ter-
mination point at the ends of the data rails. VAHLE POWERCOM
®
cables should
always be separate from power or other data conductors.
The configuration of the terminating circuit is determined by the length and type
of the conductor rails and feeder cable, and must be determined when designing
the system.

Preparation for installation
You can mount the VAHLE POWERCOM
®
485 devices on a tophat rail.
The VAHLE POWERCOM
®
485 device can be mounted only horizontally.
Comply with the following directives when designing your device configuration:
–
The VAHLE POWERCOM
®
485 device is designed for heat removal by natu-
ral convection. Therefore leave a clear space of at least 30 mm above and be-
low the device to ensure heat removal. (see Figure 4).

Space for heat dissi-
pation VAHLE
POWERCOM
®
–
A mounting depth of at least 175 mm is required for installing the VAHLE
POWERCOM
®
COM 485 device in a switch cabinet.
–
Set up the devices such that adequate space is available for wiring the con-
nections.
–
Choose the installation location such that the climatic limit conditions speci-
fied under the technical data are maintained.
