Elektrical Installation
2.2.1
Supply voltage
Proceed with start-up generally as follows:
•
Attach the supply voltage for the device to X1
•
Turn the power supply on
The supply voltage connection of the control component from the device has polarity
protection.
If several connection points are available for the identical potential, than no potential difference
between them is allowed. Otherwise, the resulted compensation currents can lead to irreversible
damages of the device. Therefore, provide a suitable equipotential bonding!
For the 24 V
–
supplier ensure a reliable electrical isolation of the low voltage. Only use power
supply units manufactured to the standards IEC 364 - 4 - 41 / HD 384.04.41 (VDE 0100 Part
410).
Only use power supply units in accordance with SELV and PELV specifications!
The supply voltage may be intermediate within the specified voltage range! Otherwise this may
cause malfunction on the device. See the technical specifications for the supply voltage
requirements.
High frequency radiation, from mobile phones for example, can cause unintentional operating
situations.
2.2.1.1
2.2.1.1 Connectors for power supply
For the connectors only use the specified manufacturer types, unequal connectors can damage the pin
connectors.
All plug connectors have to be plugged correctly, otherwise a contact resistance occurs.
Press on the plugs on several places and hold for a few seconds until they lock.
Never disconnect plugs when under load.
Faulty or incorrect connection may cause malfunction on the device
2.2.2
EMC-compliant design
The basis for an interference-free operation is an EMC-compliant hardware construction of the system, as
well as the use of interference-free cables
.
The guidlines for interference-free installation of your system
are accordingly to the installation of the devices.
