2.1 Important installation notes
Safety regula-
tions
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 starting internal work.
k Inside the device, safety clearances meet the requirements for double insu-
lation.
When fitting the connecting cable, ensure that the cables are fitted accord-
ing to regulations and that the safety clearances are maintained.
Fuse protection
k Fuse protection of the supply lead in accordance with the VDE regulations
must be installed when wiring the voltage supply in the power section. The
supply protection can also be achieved by a circuit-breaker in the supply
lead. The circuit-breaker must correspond to the power consumption of the
power controller.
k For UL application, it must be ensured that the fuse for the supply protec-
tion of the control electronics is between 2 A and a maximum of 5 A. This
also applies to the fan connection.
k To protect the power controller in the event of an earth fault, a semi-con-
ductor fuse is installed. In the event of a defect, these may only be replaced
with original JUMO semi-conductor fuses.
v Chapter 8.2 "Replacing a defective semi-conductor fuse"
Wiring Supply voltage and control cables are to be wired isolated from one another.
For supply protection, fuses (e.g. 2 A Neozed) must also be installed in the
control circuit.
PE connection
h A direct connection must be provided between the PE conductor of 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 conductors to the power section. In the event
that the protective conductor is not a component of the supply lead or its en-
casement, the selected conductor cross section may not be less than
2.5 mm
2
(for mechanical protection) or not less than 4 mm
2
(if the protection
conductor is not protected mechanically).
v See VDE 0100 Part 540
Check
h That the data given on the nameplate (rated load voltage, load current) cor-
responds to the data for the system.
h That, if the economy circuit configuration is used, the rotary electrical field
has clockwise phasing.
