•
Above 2000 m above sea level, the air and creeping distances are only sufficient
for overvoltage class II according to EN 60664. At altitudes above 2000 m above
sea level limiting measures must be taken, which reduce the line side overvoltage
from category III to category II for the entire system.
•
If a protective electrical separation (in accordance with EN 61800‑5‑1 and
EN 60204‑1) is required, then implement this outside the product at altitudes of
more than 2000 m above sea level.

Electrical installation
Ensure that all of the required covers are correctly attached after carrying out the elec-
trical installation.
Make sure that preventive measures and protection devices comply with the applica-
ble regulations (e.g. EN 60204-1 or EN 61800-5-1).
3.8.1
Required preventive measure
Make sure that the product is correctly attached to the ground connection.
3.9
Protective separation
The product meets all requirements for protective separation of power and electronics
connections in accordance with EN 61800-5-1. To ensure protective separation, all
connected circuits must also meet the requirements for protective separation.
3.10
Startup/operation
Observe the safety notes in the chapters "Startup" and "Operation" in the documenta-
tion.
Make sure that the present transport protection is removed.
Do not deactivate monitoring and protection devices of the machine or system even
for a test run.
Make sure the connection boxes are closed and screwed before connecting the sup-
ply voltage.
Depending on the degree of protection, products may have live, uninsulated, and
sometimes moving or rotating parts, as well as hot surfaces during operation.
Additional preventive measures may be required for applications with increased haz-
ard potential. You have to check the protection devices after each modification.
When in doubt, switch off the product whenever changes occur in relation to normal
operation. Possible changes are e.g. increased temperatures, noise, or oscillation. De-
termine the cause. Contact SEW‑EURODRIVE if necessary.
When the device is switched on, dangerous voltages are present at all power connec-
tions as well as at any connected cables and terminals. This also applies even when
the product is inhibited and the motor is at standstill.
Do not separate the connection to the product during operation.
This may result in dangerous electric arcs damaging the product.
