24 V supply connection
The 24 V supply is connected via a 3-pin terminal block (see 󹪝gure) at connector X1 of the
connection board on the rear of the machine control panel (see 󹪝gure: " Rear side of MPP 464 IE
with interfaces" in Section: "Interfaces" > "Overview").
The protective ground is secured to the M5 bolt.
NOTICE
Damage to the device caused by unfused supply voltages
The 24 V DC power supply must always be grounded and designed as Protective Extra-Low
Voltage (PELV) - protection by functional extra low voltage with safe isolation!
