k The choice of cable material, the installation, and the electrical connection
of the device must conform to the requirements of VDE 0100 "Regulations
on the Installation of Power Circuits with Nominal Voltages below AC
1000 V" or the appropriate local regulations.
k The electrical connection must only be carried out by qualified personnel.
k An isolating switch should be wired between the voltage supply and the de-
vice to be able to disconnect the device from the voltage supply on all
poles prior to accessing the inner parts of the device.
k Inside the device, safety clearances meet the requirements for double insu-
lation.
When mounting the connecting cable, ensure that the cables are fitted ac-
cording to regulations and that the safety clearances are maintained.
k Fuse protection of the voltage supply in accordance with the VDE regula-
tions must be installed when wiring the voltage supply in the power section.
The supply can also be protected with a circuit-breaker in the supply lead.
The circuit-breaker must correspond to the power consumption of the pow-
er controller.
k The connecting cables used for the terminals U1, U2, N/L2, V, and L1 must
have an electric strength of AC 500 V.
k For UL applications, the fuse for the supply protection of the control elec-
tronics must be between 2 A and a maximum of 5 A. This also applies to
the fan connection.
k A semiconductor fuse is installed to protect the power controller in the
event of a ground fault. In the event of a defect, these may only be replaced
with original JUMO semiconductor fuses.
v Chapter 8.2 "Replacing a defective semiconductor fuse"
Control cables (SELV potential) must be routed so that they are isolated from
cables with mains voltage potential. For supply protection, fuses (e.g. 2 A,
Neozed type) must also be installed in the control circuit.
h A direct protection conductor connection must be provided between the
power controller and the PE conductor of the supply network. Connection
takes place at the PE connection terminal.
The cross section of the PE conductor must be at least as large as the cross
section of the voltage supply cables in the power section. In the event that the
protective conductor is not a component of the supply lead or its encasement,
the selected conductor cross section may not be less than 2.5 mm
chanical protection) or not less than 4 mm
protected mechanically).
