DC link adapter

9.1

Description

The DC link adapter is used to directly feed the DC link voltage in the drive line-up. It is
required for the High Frequency Drive if the infeed is realized via an Active Line Module in
the chassis format. The supply is established at the side through the HF Damping Module.
The connecting cable cross-section should be selected based on the total current required
for all of the connected components. Shielded individual cores are recommended.
The connection cables must be fused accordingly.

Safety instructions for the DC link adapter

Danger to life if the fundamental safety instructions and remaining risks are not carefully
observed
The non-observance of the fundamental safety instructions and residual risks stated in
Chapter 1 can result in accidents with severe injuries or death.
• Adhere to the fundamental safety instructions.
• When assessing the risk, take into account remaining risks.
Danger to life through electric shock when the protective cover of the DC link is open
Touching live components results in death or severe injury.
• Only operate the components with closed protective cover.
Danger to life through 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 5 minutes after
the power supply has been switched off.
Touching live components results in death or severe injury.
• Do not open the protective cover of the DC link until 5 minutes have elapsed.
• Measure the voltage before starting work on the DCP and DCN DC-link terminals.
