S300 Product Safety Guide | 2 English
Automatic Restart!
The drive might restart automatically after power on, voltage dip or interruption of the supply
voltage, depending on the parameter setting. Risk of death or serious injury for humans work-
ing in the machine. If the parameter AENA is set to 1, then place a warning sign to the
machine (Warning: Automatic Restart at Power On) and ensure, that power on is not pos-
sible, while humans are in a dangerous zone of the machine. In case of using an under-
voltage protection device, you must observe EN 60204-1.
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 900V. Do not open or touch the equip-
ment during operation. Keep all covers closed.
During operation, SERVOSTAR 300 may have uncovered live sections, according to their
level of enclosure protection.
Lethal danger exists at live parts of the device. Built-in protection measures such as insu-
lation or shielding may not be removed. Work on the electrical installation may only be per-
formed 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 SERVOSTAR 300 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 product from the supply voltages (mains supply and 24V sup-
ply) 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 STO safety implementation on the SERVOSTAR 300 is certified. 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 without permission by the manufacturer. Opening the
housing causes loss of warranty.
