The feed must be grounded (TN-S network). The plant into which the
podis
systems are to be integrated
should be connected to the protective ground (neutral point of the mains transformer). If this is not the
case, every consumer connected to the
podis
®
flat cable must be separately connected to the neutral
point of the mains transformer through a protective conductor. The diameter of the protective conductor
must be at least 4 mm
2
. The protective conductor may not be looped through the consumers.
Effective lightning protection measures must be fitted to the plant in order to prevent damage to elec-
tronic devices.
The safe electric separation between main and auxiliary circuits is required for the motor starters. The
main and auxiliary circuits are constructively separated in the
podis
®
system in a safe and secure manner.
When connecting motor/contactor combinations made by third party manufacturers, make sure that
electric separation is guaranteed for these devices (separation voltage of at least 2.5 kV AC).
Regarding the 24 V or 50 V supply, make sure that lightning protection measures are fitted and the low
voltage supply is separated in an electrically safe manner.

CAUTION
The flat cables are not non-trailing cables.
When routing the flat cables inside cable ducts, you must consider the derating according to VDE 0660
Part 507 and the maximum ambient temperature of 50°C. Please also consider the following diagram
regarding the derating.
