5.1 Electrical connection
The connection of the attachable indicator is made via simply plugging it
between an existing transmitter and connector using a specific adapter
design for connectors to DIN 175301-803 A.
No separate supply voltage is needed since the instrument is powered
directly from the measuring current.
The connection and commissioning should only be carried out
by skilled, qualified personnel. An incorrect connection could
damage the indicator.
CAUTION!
Note the maximum permissible input current of 40 mA!
5.2 Pin assignment
The assignment of the angular connector is designed for the most commonly
used configuration for the respective input signal. Since this assignment is
not standardised, it can happen that the assignment for the connected trans-
mitter does not match the assignment of the attachable indicator.
