Signal from a 2-wire inductive proximity
sensor (NAMUR). NOTE: When using
a NAMUR input, the terminals 5 and 6
must be jumpered.
Signal from capacitive or inductive
switches, type NPN or PNP, 3 wires.
NOTE: when using a NPN or PNP input, the terminals 6 and 7 must be
jumpered.
Signal from a PNP/NPN encoder
Mounting
Insert the instrument into the panel and fasten it by fixing the two lateral
brackets (1) supplied with the instrument to the appropriate location (2),
and subsequently locking them by means of the 2 screws (3) supplied
with the instrument.
Connections
According to the requirements of EN61010-1 the power supply
input of the instrument to be connected to the mains must be
protected against short circuit by means of appropriate fuses
(see "power supply input").
