COSMOS DRIVER SERIES 3000 - USE AND MAINTENANCE MANUAL
5.2 Electrical installation
For all models of COSMOS 3000, the connectors and their position as to the driver plastic body are identical. The
electrical wiring is possible through removable connectors, in order to install and remove the drivers from the electrical
panel more easily.
The following pictures represent the Type 3250, taken as an example.
5.2.1 Power installation
Due to the presence of high capacitance inside the driver, all power wiring must be connected or
disconnected when the main power supply is absent for at least 6 minutes.
We consider as power wiring, the mains and auxiliary voltage, the motor output, the DC BUS voltage, the dynamic brake
resistor.
The upper side houses the main power supply input (LINE J1), the DC BUS voltage (DC BUS J3) and the output for the
dynamic brake resistor (BRAKE R J2).
The bottom side houses the auxiliary voltage input (24VDC J5) and the motor output (MOTOR J4).
