There are two types of electrical terminals:
• Current-carrying, which is for conductors that have a cross section
2
of up to 4 mm .
• Voltage connector, which is for conductors up to 2,5 mm
intended for all voltage signals.
The current-carrying terminals are located on position X11. These termi-
nals are feed-through terminal blocks with flat tabs on the internal side.
The voltage connector terminals are divided into two parts:
• A female part for conductor connections.
• A male part mounted inside the case on a circuit board.
All external connectors located on the back side of the case are marked
with designation labels. The female part of the connector is marked with
the same designation label as the male part.
