Startup (i.e. start of regular operation) is permitted with adherence to EMC guideline
only.
Technical data and information on the connection conditions are provided on the
nameplate and in the documentation. Comply with the data and conditions.
2.4 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:
• Before transportation, cover the connections with the supplied protection caps.
• Place the product only on the base plate during transport.
• Ensure that the product is not subject to mechanical impact.
If necessary, use suitable, sufficiently dimensioned handling equipment.
2.5 Setup and installation
Ensure that the product is installed and cooled according to the regulations in the doc-
umentation.
The product is suited for operation on laboratory benches and on tables. Use standard
laboratory or training equipment where the products can be placed properly and safely
without posing any risk to the learners.
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.
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
2.6 Electrical connection
Familiarize yourself with the applicable national accident prevention regulations before
working on the product.
Perform electrical installation according to the pertinent regulations (e.g. cable cross-
sections, fusing, protective conductor connection).
Ensure that all of the required covers are correctly attached after the electrical installa-
tion.
The preventive measures and protection devices must comply with the applicable reg-
ulations (e.g. EN60204-1 or EN61800-5-1).

Safety notes
Startup and operation
Operating Instructions – Star/Delta Switchover Module 9
Ground connections are required as preventive measures.
2.7 Startup and operation
Before startup, make sure that the 4mm sockets, buttons, and switches are intact.
It might be necessary to equip locations where such devices are used with additional
monitoring and protection devices in accordance with the respective applicable safety
regulations, e.g. the law governing technical equipment, accident prevention regula-
tions, etc.
Depending on the degree of protection, products may have live, uninsulated, and
sometimes moving or rotating parts, as well as hot surfaces during operation.
Cover unused connections with the supplied protection caps during operation.
Make sure the connection boxes are closed and screwed before connecting the sup-
ply voltage.
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.
Electric shock due to moving the device while voltage is applied. Do not move the
product while voltage is applied.
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 compon-
ents or power connections because capacitors might still be charged. Observe the fol-
lowing 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.
Mechanical blocking or internal protective functions of the product can cause a motor
standstill. Eliminating the cause of the problem or performing a reset may result in the
drive restarting 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.
2.8 Inspection and maintenance
Only perform maintenance and repair work once the product has been secured and
disconnected from the power supply. Ensure a de-energized state of the product be-
fore you start working on it. Ensure a de-energized state for the entire time you work
on the product.
Repair work may only be carried out by SEW‑EURODRIVE.
