AKD2G-S Installation Manual, Safety 1 | 3 Product Safety
Observe electrostatically sensitive components!
The devices contain electrostatically sensitive components which may be damaged by incorrect handling.
Electrostatically discharge your body before touching the device. Avoid contact 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 protection 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 cabinet 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 electrical arcing with
damage to contacts and personal injury. Wait at least 5 minutes after disconnecting 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!
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 components meet these requirements.
Never modify the drive!
It is not allowed to modify the drive hardware without permission by the manufacturer. Opening the housing causes
loss of warranty.
High noise pollution!
Fans generate noise of up to 76 dBA when operating at maximum load. This can lead to hearing damage.
Keep the cabinet doors closed during operation. Use ear protection if the control cabinet has to be opened
during servicing. The operator must provide ear protection and monitor its use depending on the daily noise
exposure level determined.
