2.5 Safety and Protection
2.5.1 Fuses and cable cross-sections
The fuses and wire cross-sections allocated for power-side connections
depend on the rated mains current ILN of the Rapid Link power bus
(without mains reactor).
The national and regional standards (e. g. VDE 0113, EN 60204) must be
observed and the necessary approvals (e. g., UL) at the site of installation
must be fulfilled.
When the device is operated in a UL-approved system, use only UL-approved
fuses, fuse bases and cables.
The leakage currents to ground (to EN 50178) are greater than 3.5 mA.
The connection terminals marked PE and the enclosure must be connected
to the ground circuit.
The cross-sections of the cables and cable protection fuses used must
correspond with local standards.
For an installation in accordance with UL guidelines, the fuses and copper
cable that are UL-approved and have a heat-resistance of +60/75 °C are to
be used.
For a permanent installation with insulation, use power cables that are
suitable for the specified mains voltages.
For RASP5 a fully (360°) shielded low-impedance-screened cable on the
motor side is required. The length of the motor cable depends on the RFI
class and must not exceed 20 m for RASP5.
ATTENTION
When selecting the cable cross-section, take into account the
voltage drop under load.
The consideration of other standards (e. g. VDE 0113 or
VDE 0289) is the responsibility of the user.
ATTENTION
The specified minimum PE conductor cross-sections
(EN 50178, VDE 0160) must be maintained.
￫
Choose the cross-section of the PE conductor in the motor lines
at least as large as the cross-section of the phase lines (U, V, W).
