Supply voltage
The power supply is connected in a three-pole connector, that has terminals
numbered 7, 8, and 9. The supply is brought to terminals 7 and 9. The polarity does
not matter. The 24VDC model has green connector block, while the 230VAC model
has a grey one.
The 230VAC model is built with a reinforced insulation, so a protective earth connection is not
needed.
The meter has internal pre-fuse. If an external is used, it should be at least 2AT for 24VDC
model and 500mAT for 230VAC model.
Other cards
See the chapters of the card types.
