AKD-C Installation | 3 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.
Earthing!
It is vital that you ensure that the device 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!
AKD-C with AKD-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 AKD-C.
Lethal 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, AKD-C 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 AKD-C while it is live. There is a danger of elec-
trical arcing with damage to contacts and personal injury. Wait at least 7 minutes after dis-
connecting the product from the supply voltages (mains supply and 24V supply) before
touching potentially live sections of the equipment (such as contacts) or removing any con-
nections.
Always measure the voltage in the DC bus link at connector X14 and wait until the voltage is
below 50 V before handling components.
Functional Safety
The STO safety implementation on the AKD is certified. The safety circuit implementation
used for the safety function "Safe Torque Off" in the drive is suited for SIL 2 according to IEC
62061 and PLd / CAT3 according to ISO 13849-1. The assessment of the safety functions
according to EN13849 or EN 62061 must finally be done by the user.
Never modify the product!
It is not allowed to modify the product without permission by the manufacturer. Opening the
housing causes loss of warranty.
