Preparing the device for operation
CAUTION
Interference-proof connections for undisturbed operation
For all signal connections, use screened cables and metal connectors only.
All plug-in connections must be screwed or locked into place.
This will improve their electrical shielding.
Signal cables must not be routed in the same cable duct with power cables.
Before commissioning the system, check all cable connections.
Make sure that all voltages and signals have the required values.
CAUTION
Safely diverting electrical interference currents
The device and the control panel must be connected to a central earth point with as
short a conductor length as possible.
The connection between the device and the control panel must have as low a
resistance as possible.
The earth connection must be implemented using a green and yellow cable with a
minimum cross-sectional area of 6 mm².
Emitted interference as per EN 55022:2010 Class A and EN 61000-6-4:2007
WARNING
Devices with a 24 V DC supply
The device should only be run with safety extra-low voltage (functional extra-low
voltage with protective separation).
The power transformer must meet all applicable standards.
