Manual – EtherCAT® Interfaces, Field Distributors 11
3.5 Functional safety technology
The product must not perform any safety functions without a higher-level safety sys-
tem, unless explicitly allowed by the documentation.
3.6 Transport
Inspect the shipment for damage as soon as you receive the delivery. Inform the ship-
ping company immediately about any damage. If the product is damaged, it must not
be assembled, installed or started up.
Observe the following notes when transporting the device:
• Ensure that the product is not subject to mechanical impact.
• Before transportation, cover the connections with the supplied protection caps.
• Only place the product on the cooling fins or on the side without connectors during
transportation.
• Always use lifting eyes if available.
If necessary, use suitable, sufficiently dimensioned handling equipment.
Observe the information on climatic conditions in the chapter "Technical data" of the
documentation.
3.7 Installation/assembly
Ensure that the product is installed and cooled according to the regulations in the doc-
umentation.
Protect the product from strong mechanical strain. The product and its mounting parts
must never protrude into the path of persons or vehicles. Ensure that components are
not deformed and insulation spaces are not changed, particularly during transportation
and handling. Electric components must not be mechanically damaged or destroyed.
Observe the notes in chapter "Mechanical installation" (→ 224) in the documenta-
tion.
3.7.1 Restrictions of use
The following applications are prohibited unless the device is explicitly designed for
such use:
• Use in potentially explosive atmospheres
• Use in areas exposed to harmful oils, acids, gases, vapors, dust, and radiation
• Operation in applications with impermissibly high mechanical vibration and shock
loads in excess of the regulations stipulated in EN61800-5-1
• Use at an elevation of more than 4000m above sea level
The product can be used at altitudes above 1000 m above sea level up to 4000 m
above sea level under the following conditions:
• The reduction of the nominal output current and/or the line voltage is considered
according to the data in chapter "Technical data"(→2120) in the documentation.
25809148/EN – 01/2019

3Safety notes
Electrical installation
Manual – EtherCAT® Interfaces, Field Distributors
12
• 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.
3.8 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.
25809148/EN – 01/2019

Safety notes
Startup/operation
Manual – EtherCAT® Interfaces, Field Distributors 13
If you disconnect the product from the voltage supply, do not touch any live compon-
ents or power connections because capacitors might still be charged. Observe the fol-
lowing minimum switch-off time:
1minute.
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.
Mechanical blocking or internal safety functions of the product can cause a motor
standstill. Eliminating the cause of the problem or performing a reset may result in the
drive re-starting automatically. If, for safety reasons, this is not permitted for the drive-
controlled machine, 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.

4.3.5 Maintenance switch
The maintenance switch with line protection can be secured with 3 locks.
For the designs MFZ26J, MFPZ28J, and MFZ29J, the maintenance switch offers an
integrated feedback option for the current position. Feedback is evaluated by the DI0
binary input. For further information, refer to the chapter "Connecting MFE72 fieldbus
interface inputs/outputs"(→252).
