PC Voltage Supply X10, X20
X10 - DC 24 V voltage supply
This connection is used for device variants for DC 24 V. All internally required
voltages are generated with electrical isolation via a DC/DC converter. The
connection is designed as connector terminal MSTB 1.5, 4-pin. To this con‐
nector terminal, cables with a cross-section of maximum 1.5 mm
connected.
NOTICE
For terminal connectors use copper wire only. Tighten the screws of the screw
terminals with a torque of 5.5 lb in (0.6 Nm).

DANGER
The DC 24 V input voltage must comply with the requirements of the "Protective
separation"!
Plug and unplug the connector only if there is no voltage!
