More Information

Overview Manuals Power Behavior Thermal Zones Enclosure Sides Vertical Mounting

Features:

  • The PPU 260.2 combines SINUMERIK 828D CNC hardware with a vertical operator-facing panel.
  • A 24 V DC input supplies the complete unit, with documented buffering for short input interruptions.
  • The closed front reaches IP65 while the rear electronics remain IP20 and UL open type.
The vertical construction lets the PPU front occupy the machine-panel opening while the electronics project into the protected enclosure.

Front and rear operating temperatures are specified separately because the two sides experience different thermal conditions.

Power continuity depends on the supply arrangement: the extended buffering figure applies only with the stated SITOP smart source.

The Siemens 6FC5370-6AA20-0AA0 SINUMERIK 828D PPU 260.2 may still be available for purchase and support from Apter Power beyond End-Of-Life (EOL) by the manufacturer (OEM).

Relating the 24 V input to ride-through time

  • Input boundary: The PPU accepts the specified tolerance around its 24 V DC rated supply.
  • Unit demand: The complete panel processing unit is designed around a maximum 60 W power requirement.
  • Standard buffering: Without the named auxiliary supply arrangement, the documented mains buffering time is three milliseconds.
  • SITOP condition: Twenty milliseconds applies when the PPU is operated with the specified SITOP smart power supply.

Separating front and rear temperature limits

  • Operator side: The front section is rated for operation from 0 to +45 °C.
  • Cabinet side: The rear section extends to +55 °C when the enclosure maintains the required conditions.
  • Storage state: The non-operating storage range is distinct from both operating zones.
  • Humidity control: Operating, storage and transport each have their own relative-humidity boundary.

Applying protection to the correct face

  • Closed front: IP65 applies to the operator face only while the front flap is closed.
  • Rear electronics: The cabinet-facing side is IP20 and UL open type.
  • Panel opening: The machine enclosure must protect the rear rather than extending the front rating to the whole PPU.
  • Access flap: Opening the front flap removes the condition under which the documented IP65 front rating is stated.

Keeping the PPU in its documented orientation

  • Device position: Both the PPU mounting direction and operator-panel orientation are vertical.
  • Panel cutout: The front sits at the machine surface while the electronic depth remains behind the panel.
  • Ventilation path: Cabinet airflow must serve the rear electronics within their higher operating-temperature limit.
  • Mechanical check: The mounting surface must accommodate the complete panel dimensions and rear clearance.
Description
Siemens 6FC5370-6AA20-0AA0 is the vertically arranged PPU 260.2 panel processing unit for a SINUMERIK 828D CNC system. It places the operator-facing panel and the control electronics in one CNC hardware assembly.

The 24 V DC input of 6FC5370-6AA20-0AA0 feeds a unit with a documented maximum power demand of 60 W. Normal mains buffering is three milliseconds, while the stated twenty-millisecond value applies only when the PPU is supplied through the specified SITOP smart power supply.

Thermal limits differ across 6FC5370-6AA20-0AA0: the front operating area is rated to +45 °C, whereas the rear electronics can operate to +55 °C. This split ties cabinet ventilation to the rear section even when the operator side remains inside its own limit.

Installed vertically, 6FC5370-6AA20-0AA0 presents an IP65 front only when the front flap is closed. The rear remains IP20 and UL open type, so the machine-panel cutout and enclosure must protect the rear electronics rather than treating the whole assembly as IP65.

Technical notes
Siemens 6FC5370-6AA20-0AA0 is the vertical PPU 260.2 hardware version. Its front and rear temperature and enclosure limits are different and should be checked separately.

FAQS

The following is a list of questions commonly asked by our customers. Please contact us if you have a question about our process that is not answered below.
Why can the front and rear of 6FC5370-6AA20-0AA0 not be assigned the same protection rating?
With its flap closed, 6FC5370-6AA20-0AA0 is IP65 at the front but IP20 and UL open type at the rear, which remains enclosure-dependent.
What changes the buffering time stated for 6FC5370-6AA20-0AA0?
The normal value for 6FC5370-6AA20-0AA0 is three milliseconds; twenty milliseconds applies only with the specified SITOP smart power supply.
How should cabinet temperature be evaluated around 6FC5370-6AA20-0AA0?
Check both sides of 6FC5370-6AA20-0AA0: the operator front is limited to +45 °C, while the rear electronics are rated to +55 °C.
Which mounting orientation belongs to 6FC5370-6AA20-0AA0?
The documented mounting position for 6FC5370-6AA20-0AA0 is vertical, including the operator-panel orientation.
Can a 24 V DC source be selected only from the nominal value for 6FC5370-6AA20-0AA0?
No. The source for 6FC5370-6AA20-0AA0 must also satisfy the +20% / -15% input tolerance and the complete unit demand.
What should be checked if 6FC5370-6AA20-0AA0 operates at the front but overheats inside the cabinet?
Verify rear-side airflow and temperature around 6FC5370-6AA20-0AA0, because the cabinet-facing electronics have a separate environmental zone from the front.
