Wiring Of The Power Supply Input - Weidmuller Transclinic 8i+ Bedienungsanleitung

3.4 Wiring of power supply inputs
The power supply input of this equipment is floating with regards to the rest of the
circuit. This is accomplished by means of a dedicated DC/DC converter which provides
a double insulation barrier between the power supply input and the PV-side terminals.
From the user perspective this means full safety even under severe surges.
This equipment must be powered by an external, galvanically isolated and dedicated
power supply, normally mounted inside the same combiner box where the Transclinic
resides. These are the recommended Weidmüller power supplies:
8739140000 CP SNT 48W 24V 2A
8951330000 CP M SNT 70W 24V 3A
CAUTION
This equipment is marked with the DC symbol because it is fed with
DC power.
