AKD2G-S Installation, Safety 1 | 3 Product Safety
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.
High voltages!
The equipment produces high electric voltages up to 900 V. Lethal danger exists at live parts
of the device. Do not open or touch the equipment during operation. Keep all covers and cab-
inet doors closed. Built-in protection measures such as insulation or shielding may not be
removed. Work on the electrical installation may only be performed by trained and qualified
personnel, in compliance with the regulations for safety at work, and only with switched off
mains supply, and secured against restart.
Never undo any electrical connections to the drive 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 drive from the main supply power before touching potentially live sections of
the equipment (such as contacts) or removing any connections.
Always measure the voltage in the DC bus link and wait until the voltage is below 50 V
before handling components.
Functional Safety!
Beta drives: Safety functionality is not approved nor certified. Do not use this functionality in
applications with functional safety request.
The assessment of the safety functions according to EN13849 or EN 62061 must finally be
done by the user.
Reinforced Insulation
Thermal sensors, motor holding brakes and feedback systems built into the connected motor
must have reinforced insulation (according to IEC61800-5-1) against system components
with power voltage, according to the required application test voltage. All Kollmorgen com-
ponents meet these requirements.
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.
