Observe electrostatically sensitive components!
The devices contain electrostatically sensitive components which may be damaged by incor-
rect handling. Electrostatically discharge your body before touching the device. Avoid con-
tact with highly insulating materials (artificial fabrics, plastic film etc.). Place the device on a
conductive surface.
Hot surface!
Drives may have hot surfaces during operation. The housing can reach temperatures above
80°C. Risk of minor burns! Measure the temperature, and wait until the housing has cooled
down below 40 °C before touching it.
Earthing!
It is vital that you ensure that the drive is safely earthed to the PE (protective earth) busbar in
the switch cabinet. Risk of electric shock. Without low-resistance earthing no personal pro-
tection can be guaranteed.
Leakage Current!
Since the leakage current to PE is more than 3.5 mA, in compliance with IEC61800-5-1 the
PE connection must either be doubled or a connecting cable with a cross-section >10 mm²
must be used. Deviating measures according to regional standards might be possible.
Residual current protective or monitoring devices!
MKD-C with MKD-N can cause a d.c. current in the protective earthing conductor. Where a
residual current-operated protective (RCD) or monitoring (RCM) device is used for protection
in case of direct or indirect contact, only an RCD or RCM of Type B is allowed on the supply
side of MKD-C.
Lethal voltages!
The equipment produces high electric voltages up to 900V. Lethal danger exists at live parts
of the device. Do not open or touch the equipment during operation. Keep the IP 54 cabinet
doors closed during operation. Built-in protection measures such as insulation or shielding
may not be removed. Work on the electrical installation may only be performed with
switched off mains supply, and secured against restart.
Never undo any electrical connections to the MKD while it is live. There is a danger of elec-
trical arcing with damage to contacts and personal injury. Wait at least 5 minutes after dis-
connecting the product from the supply voltages before touching potentially live sections of
the equipment or removing any connections.
Ensure the MKD-N DC-Bus link cover is installed on the last MKD-N before switching on
mains power.
High noise pollution!
Fans generate noise of up to 90 dBA when operating at maximum load. This can lead to dam-
age to the hearing. Keep the cabinet doors closed during operation. Use ear protection if the
control cabinet has to be opened during normal operation. The operator must provide ear pro-
tection and monitor its use depending on the daily noise exposure level determined.
Functional Safety!
The STO safety implementation on the MKD is certified. The brake interruption input can be
used to realize an SBC function. The assessment of the safety functions according to
EN13849 or EN 62061 must finally be done by the user.
Never modify the drive!
It is not allowed to modify the drive hardware without permission by the manufacturer. Open-
ing the housing causes loss of warranty.
