WARNING: the internal circuitry will be damaged if an external power supply is
connected to X12 (J15) EPO terminals. Do not connect an external power supply or
active signal. Only Normally Closed dry contact is allowed.
The following picture shows the 2 different connection points in X12, which are X12_A and
X12_B.
There are three alternatives for connection:
a) Connecting an external Emergency pushbutton to X12_A (NC contact, without potential)
b) Installing a cable bridge/shunt to close the circuit in terminal X12_A (in case an external
EPO is not used)
c) Using the X12_A terminals to serialize an external Emergency Power Off sequence
