Notes for connecting the DC power supply:
 Be aware: The Drum can operate from either an:
o isolated DC power supply
or
o non-isolated DC power supply
 For best immunity, it is highly recommended to use twisted cables for the DC power
supply cable. A 3-wire shielded cable should be used. The gauge is determined by
the actual current consumption of the motor.
 Connect both ends of the cable shield to the closest ground connection, one end near
the power supply and the other end to the PE terminal on the Drum’s heatsink.
 For safety reasons connect the PR of the power supply to the closest ground
connection.
 To close the power supply cable into the drive, use the barrel connector, M6 spring
washer and M6 nut (in the drive). The required torque is 3-4 Nm.
 To close the PE wire into the drive, use the barrel connector, M5 flat washer, M5
spring washer and M5 screw to the heatsink. The required torque is 3-4 Nm.
3.4.2.3 Connecting the Optional Back-up Supply Cable
Power to the Drum is provided by a 12 to 195 VDC source (depending on model type). A
“smart” control-supply algorithm enables the Drum to operate with the power supply only,
with no need for an auxiliary supply voltage. If backup functionality is required for storing
control parameters in case of power-outs, an external 12-195 VDC power supply can be
connected, providing maximum flexibility and optional backup functionality when needed.
To connect the back-up supply to the Auxiliary port, use the Drum's J1 connector (CAN
communication connector). Remember, you are working with DC power so be sure to exercise
caution.
Notes for back-up supply connections:
 Use a 24 AWG twisted pair shielded cable. The shield should have copper braid.
 The source of the back-up supply must be isolated.
 For safety reasons, connect the return of
the back-up supply source to the closest
ground.
 Connect the cable shield to the closest ground near the power source.
 Before applying power, first verify the polarity of the connection.
