CompactFlash cards for users:
● The SINUMERIK CNC supports the file systems FAT16 and FAT32 for
CompactFlash cards. You may need to format the memory card if you want to use a
memory card from another device or if you want to ensure the compatibility of the
memory card with the SINUMERIK. However, formatting the memory card will
permanently delete all data on it.
● Do not remove the memory card while it is being accessed. This can result in damage to
the memory card and the SINUMERIK as well as the data on the memory card.
● If you cannot use a memory card with the SINUMERIK, it is probably because the
memory card is not formatted for the control system (e.g. Ext3 Linux file system), the
memory card file system is faulty or it is the wrong type of memory card.
● Insert the memory card carefully and the right way round into the memory card slot
(observe indicators such as arrow or similar). This way you avoid mechanical damage to
the memory card or the device.
● Only use memory cards that have been approved by Siemens for use with SINUMERIK.
Even though the SINUMERIK complies with the general industry standards for memory
cards, it is possible that memory cards from some manufacturers will not function
perfectly in this device or are not completely compatible with it (you can obtain
information on compatibility from the memory card manufacturer or supplier).
● The "CompactFlash® 5000 Industrial Grade" CompactFlash card from SanDisk has been
approved for SINUMERIK (Order Number 6FC5313-5AG00-0AA0).

2.1 Secondary electrical conditions
2.1.1 Protective Separation as per EN 61800-5-1
Prerequisite
The complete system includes user interfaces (UIs) and interfaces for servicing, startup and
maintenance.
User interfaces (UIs)
UIs are all the interfaces that are freely accessible to the machine operator without the need
for tools or aids. These user interfaces provide safe isolation up to 230 V AC according to
EN 61800-5-1.
Interfaces for servicing, startup and maintenance
DANGER
The interfaces for servicing/installation and start-up/maintenance purposes are provided
without protective separation.
If necessary, these interfaces can be isolated safely using a supplementary adapter
(insulation voltage 230 V AC). Although these adapters are not included in the Siemens
scope of delivery, you can buy these parts from your local dealer, who will be happy to
advise you.
DANGER
Safe isolation can only be ensured if the system configuration specified below is strictly
adhered to. When installing additional components with EUIs, please make sure that the
EUIs have safe isolation for at least 230 V AC.
Note
The components of the drive control comply with EN 61800-5-1 and contain only circuits and
customer terminals with class DVC A voltages and safety isolation from circuits with
dangerous voltages (PELV circuits).

2.1.2 Grounding concept
Components
The SINUMERIK 828D system consists of a number of individual components which have
been designed so that the system complies with the appropriate EMC and safety standards.
The individual system components are:
● Panel Processing Unit PPU
● Machine Control Panel
● PLC I/O devices PP 72/48D PN
Grounding measures
The PPU and MCP are attached with tensioners to a metal panel on the operator panel. Both
have a protective conductor connection for grounding (grounding screw) at the rear of the
device, which must be connected to the grounding bar of the control cabinet.
The SINAMICS S120 drive system is installed in the control cabinet. The electronics unit
grounds of the modules are connected to each other via DRIVE-CLiQ. The modules are
grounded either via the galvanized mounting plate or via the grounding lugs on the front of
the modules.
The PLC I/O device modules are installed in the control cabinet and grounded via a
grounding screw.

The following rules apply for external cable cross sections:
● PA cross-section ≥ 10 mm2
● The conductor cross-section of the external protective conductor is calculated from the
conductor cross-section of the line connection as follows:
Line connection S (mm2) External protective conductor min. (mm2)
S ≤ 16 S
16 ≤ S ≤ 35 16

2.1.3 RI suppression measures
In addition to the protective grounding of system components, special precautions must be
taken to ensure safe, fault-free operation of the system. These measures include shielded
signal cables, special equipotential bonding, isolation, and shielding measures.
Shielded signal lines
● For the safe and smooth operation of the system, the specified cables must be used.
Please refer to the chapter titled Connection.
● For digital signal transmission, the shield must have a conductive connection at both
sides of the housing.
Exception:
Standard shielded cables grounded on one side can be used for devices from other
manufacturers (printers, programming devices, etc.). However, these devices must not be
connected to the controller during normal operation. However, if the system cannot
operate without them, then the cable shields must be connected at both ends.
Furthermore, the non-Siemens device must be connected to the controller via an
equipotential bonding cable.
Cable definitions
● Signal cables (example)
– Data cables (Ethernet, PROFINET, DRIVE-CLiQ, sensor cables, etc.)
– Ribbon cables for digital inputs/outputs
– EMERGENCY OFF lines
● Power cables (example)
– Low-voltage supply cables (230 V AC, 24 V DC, etc.)
– Supply cables to contactors (primary and secondary circuit)
Rules for routing cables
In order to maximize noise immunity for the complete system (controller, power section,
machine) the following EMC measures must be observed:
● Signal cables and power cables must be routed at the greatest possible distance from
one another.
● If necessary, signal and power cables may cross one another (if possible at an angle of
90°), but must never be laid close or parallel to one another.
● Signal cables may not be routed close to strong external magnetic fields (e.g., motors
and transformers).
● Pulse-loaded HC/HV lines must always be laid completely separately from all other lines.
