Connecting The Power Supply; Connecting Devices With 24 V Dc 2-Pin - Siemens SIMATIC IFP2200 Operating Instructions Manual

3.4.3

Connecting the power supply

Depending on the device version, you can operate the device with the following voltage:
● Standard monitor and standard touch versions, PRO device: 24 V DC 2-pin
● Ethernet Monitor versions: 24 V DC 3-pin
● Extended versions: 24 V DC 2-pin or 100 to 240 V AC
Note
To turn off the device completely, disconnect it from the power supply. The device does not
have an on/off switch.
3.4.3.1

Connecting devices with 24 V DC 2-pin

Note before connecting
NOTICE
Damage to device due to inadequate cable cross-section
Using power supply cables with cross-sections that are too small can damage the device in
the event of a short circuit. Only connect cables, therefore, with a minimum cross-section of
1.3 mm
Note
The device may only be connected to a 24 V DC power supply that meets the requirements
of a safe extra-low voltage (SELV) according to IEC/EN/DIN EN/UL 60950-1.
The power supply must meet the requirements of NEC Class 2 or LPS according to
IEC/EN/DIN EN/UL 60950-1.
Since the ground/negative pole of the 24 V power supply and PE are connected to the
housing, the SELV power supply automatically becomes a PELV power supply. Bear this in
mind when connecting other devices. Additional information on the design of an SELV and
PELV power supply is available in the section "Technical specifications/Interface
description", "24 V DC Power Supply (Page 106)".
