6.2.3 Contactors
Only use contactors in utilization category AC-3 (EN 60947-4-1) as line and brake
contactors.
6.2.4 Electromagnetic compatibility (EMC)
INFORMATION
The unit can cause EMC interference within the permitted limit range according to
DIN EN 61800-3.
This unit is a drive system of the category C3 (see DIN EN 61800-3).
For detailed information on EMC-compliant installation, refer to the publication "Drive
Engineering – Practical Implementation: EMC in Drive Engineering".
6.2.5 Cable routing
Observe the following when routing the cables:
• Use suitable cables to connect power supply and communication. Refer to chapter
"Electrical connections" for descriptions of connections.
• Route power cables and signal cables in separate cable ducts.
• Maintain the greatest possible distance between power cables and signal cables.
• Avoid using long cables running parallel to one another.
For detailed information on EMC-compliant installation, refer to the publication "Drive
Engineering – Practical Implementation: EMC in Drive Engineering".
6.2.6 Installation altitude higher than 1000 m above sea level
Units with a system voltage of phase to ground of 300 V or phase to phase of 500 V
can be used at an altitude of more than 1000 m above sea level up to a maximum of
4000 m above sea level under the following conditions:
• The nominal continuous power is reduced due to the reduced cooling above
1000 m, see chapter "Technical data".
• Above 2000 m above sea level, the air and creepage distances are only sufficient
for overvoltage class 2. If the installation calls for overvoltage class 3, you will have
to install additional external overvoltage protection to limit overvoltage peaks to 2.5
kV phase-to-phase and phase-to-ground.
• If safe electrical disconnection is required, it must be implemented outside the unit
at altitudes of more than 2000 m above sea level (safe electrical disconnection in
accordance with EN 61800-5-1 and/or EN 60204-1).
• Overvoltage classes according to EN 60664
