4.5 Control voltage (24V supply)
PELV
1)
for 24V power supply unit
For the 24V supply of the devices of the Rexroth IndraDrive Mi
range, use a power supply unit or a control-power transformer
with protection by PELV according to IEC 60204-1 (section 6.4).
In the scope of CSA/UL, the data of the control-power transformer
are limited to:
●
Max. output voltage: 42.4 V
peak
or 30 V
ac
● Max. output power: 10000 VA
The data in the table below generally apply to the 24V supply of the devices
of the Rexroth IndraDrive Mi range. For other data, such as power consump‐
tion and inrush currents, see the technical data for each device.
The specified values apply at the connections (+24V, 0V) to the "24V supply"
of the devices!

Tab. 4-14: Control voltage
Overvoltage
Overvoltage greater than 33 V has to be discharged by means of
the appropriate electrical equipment of the machine or installation.
This includes:
●
24V power supply units that reduce incoming overvoltage to
the allowed value.
● Overvoltage limiters at the control cabinet input that limit ex‐
isting overvoltage to the allowed value. This, too, applies to
long 24V lines that have been run in parallel to power cables
and mains cables and can absorb overvoltage by inductive
or capacitive coupling.
Applies to all devices except HCS01 and HMV02:
Insulation monitoring impossible
The input 0 V is connected in conductive form to the housing po‐
tential. Insulation monitoring at +24 V and 0 V against housing is
impossible.
