Panel PC 670 Computing Unit, Equipment Manual
Mains supply
When connecting the device, observe the relevant information provided in
Chapter 2.
Never connect or disconnect power cables or data transmission lines during a
thunderstorm.
In an emergency situation (for instance, damage to the housing, controls or power
cable, penetration by liquids or foreign bodies), pull the power plug and contact the
authorized service department.
When plugging in/out periphery connections (e.g. keyboard, mouse, printer), the
SIMATIC Panel PC must have been switched off (not in the case of PC card and
USB devices). Failure to do so can result in damage to the computing unit.
Notes for devices with AC power supply
The device is intended for connection to grounded power supply systems
(TN networks to VDE 0100, Part 300, or IEC 364-3).
No provision is made for connection to non-grounded or impedance-grounded
power supply systems (IT networks).
The power cable should comply with the safety guidelines of the country
concerned.
Check to make sure that the rated voltage for the device corresponds to that
supplied by the local power supply.
This device is equipped with a safety-tested power supply cable and may be
connected only to a socket outlet with grounding contact.
Make sure that the socket outlet on the device or the socket outlet with grounding
contact of the building wiring system is freely accessible and located as near to the
device as possible.
To completely disconnect the PC from the mains power supply, you must pull the
plug. This connection must be easily accessible. If the PC is to be installed in a
cabinet, a central disconnector must be provided.
Note for devices with DC power supply
Devices with a DC power supply are considered open operating resources (right
side of device); therefore, the assembly design must fulfill the fire protection
housing requirements.
!
Warning
The device may only be connected to 24 V DC power supply networks which fulfill
the requirements of a safe electrical low voltage (SELV).
The cable cross-section must be large enough so that, should a short circuit occur
in the computing unit no damage is caused by the cable.
