Protective separation
The product meets all requirements for protective separation of power and electronics
connections in accordance with EN 61800-5-1. The connected signal circuits must
meet requirements according to SELV (

•
41) (single-point synchronization)
•
49) (single-point synchronization)
Make sure that any existing transport protection is removed.
Do not deactivate monitoring and protection devices of the machine or system, even
for a test run.
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. Be sure to check the effectiveness of the protection devices after every
modification.
In the event of deviations from normal operation, switch the product off. Possible devi-
ations are increased temperatures, noise, or vibration, for example. Determine 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 is also the case even if
the product is inhibited.
Do not separate the connection to the product during operation. This may result in
dangerous electric arcs damaging the product.
If you disconnect the product from the voltage supply, do not touch any live compo-
nents or power connections because capacitors might still be charged. Observe the
following minimum switch-off time:
10 minutes.
Observe the corresponding information signs on the product.
The fact that the operation LED and other display elements are no longer illuminated
does not indicate that the product has been disconnected from the supply system and
no longer carries any voltage.
Cover unused connections with the supplied protection caps during operation.
Mechanical blocking or internal protective functions of the product can cause the
power to interrupt. Removing the cause of this problem or performing a reset can re-
sult in the machine or system restarting on its own. If this is not permitted for the drive-
controlled machine or system for safety reasons, first disconnect the product from the
supply system and then start troubleshooting.
Risk of burns: The surface temperature of the product can exceed 60 °C during opera-
tion. Do not touch the product during operation. Let the product cool down before
touching it.
