Safety instructions

Only skilled persons are permitted to carry out the work necessary to install, put into service and run a
device or system.
DANGER
Follow the basic safety rules when working with electricity. Observe the information on rated voltage
and supply voltage specified in the technical data!
DANGER
Connect the CP305 exclusively according to the connection diagram in this chapter. Do not make any
changes to the internal wiring. Non-compliant connection or arbitrary changes can lead to serious
malfunctions or even complete failure of the CP305.
CAUTION
Electrostatic discharge sensitive devices
Observe the precautions for handling electrostatically sensitive devices.
Damage to components
Do not remove the device from the enclosure while it is in operation. Disconnect the device from the
power supply and the network (Ethernet) beforehand.
Damage to the device due to incorrect connection plug
Connectors of other devices may have polarity that differs. You are required to use the enclosed
connector plug (A1/+, A2/-).
Safe separation
The power supply must be properly insulated from hazardous voltages and meet the limits of UL/CSA
6101010-1 (6.3).
To comply with the requirements of DIN VDE 0100-710, AC power supplies with max. 25 VAC must be used.
All enclosed connectors should always be plugged in even when they are not in use.
PELV
If a DC power supply unit is used to supply one or more CP305 devices, A2/- can be connected to protective
earth. Then shielded Ethernet cables can also be used.
SELV
If an AC or DC power supply without a secondary connection between A2/- and protective earth is used to
supply one or more CP305 devices, unshielded Ethernet cables must be used.
Danger of electric shock!
