PM340 Power Modules in blocksize format, frame sizes FSA to FSF

The PM340 Power Modules in blocksize format feature the following connections and interfaces as standard:

• Line supply connection
• PM?IF interface for connection of the PM340 and CU305 Control Unit. The PM340 Power Module also supplies power to the CU305 Control Unit by means of an integrated power supply.
• Terminals DCP/R1 and R2 for connection of an external braking resistor
• Motor connection made with screw terminals or screw studs
• Control circuit for the Safe Brake Relay for controlling a holding brake
• 2 PE/protective conductor connections

PM340 Power Modules without integrated line filter can be connected to grounded TN/TT and non-grounded IT systems.
PM340 Power Modules with integrated line filter are suitable only for connection to TN systems with grounded star point.

The integrated braking unit (braking chopper) is rated with the capability to continuously utilize the external braking resistor. The temperature of the external braking resistor must be monitored to provide protection against thermal overloading.
