Phoenix 1745894 FMC 1.5 / 2-ST-3.81, article number 1745894
The terminals are spring-loaded terminals.
Permissible conductor cross-sections:
● For single-conductor cables or for flexible cables with end sleeves without plastic protection:
– 0.25 mm
– AWG: 24 ... 16
● For flexible cables with end sleeves with plastic protection:
– 0.25 mm
– AWG: 24 ... 19
Also connect the conductors for the motor holding brake to the connector at X107, even when
you are using a motor without holding brake.

Explanation
If you are using the internal braking resistor, DCP
and R2 must be jumpered. If you are using the
external braking resistor, remove the jumper be‐
tween DCP and R2.
Connect the external braking resistor via the DCP
and R1 terminals.
