Configuring relays for disconnecting DC variable stages
This section is for PBx Power Blocks only.
Many variable frequency drives require a disconnect relay to start and stop operation. When
configured as a disconnect relay, the relay switches off when the DC stage it is assigned to is off.
Configuring relays for disconnecting DC variable stages means selecting the function and entering a
descriptive name.
Use the Installation and configuration worksheets when configuring Power Blocks.
The worksheets are in the back of the Power Block installation guide..
