4.2 Safety instructions for Adapter Modules
WARNING
Electric shock due to the residual charge of the DC link capacitors
Because of the DC link capacitors, a hazardous voltage is present for up to five minutes after
the power supply has been switched off.
Contact with live parts can result in death or serious injury.
● Open the protective cover of the DC link and only remove/insert the hybrid cable after 5
minutes have elapsed.
● Before starting any work, also check that the system is in a voltage-free state by measuring
at the DC link terminals DCP and DCN.
WARNING
Electric shock due to high leakage currents caused by an interrupted external protective
conductor
Drive components conduct high discharge currents via the protective conductor. Touching
conductive parts when the protective conductor is interrupted can result in death or serious
injury.
● Ensure that the external protective conductor satisfies at least one of the following
conditions:
– It has been laid so that it is protected against mechanical damage.
1)
– If it is a single cable, it has a cross-section of at least 10 mm² Cu.
– If it is a conductor of a multi-conductor cable, it has a cross-section of at least 2.5 mm²
Cu.
– It has a second protective conductor in parallel with the same cross-section.
– It complies with the local regulations for equipment with increased leakage current.
1)
Cables routed within control cabinets or closed machine housings are considered to be
adequately protected against mechanical damage.
WARNING
Electric shock due to incorrect connection to the DC link
Incorrectly established connections can result in overheating and therefore fire with
associated smoke. There is also a risk of an electric shock. This can result in serious injury or
death.
● Use only adapters (DC link adapters and DC link infeed adapters) approved by Siemens
for connection to the DC link.
