Electrical Connection - ABB CP-Serie Betriebs- Und Montageanleitung

(GB) Mounting:
1. Fasten the DIN rail (TH 35-15 or TH 35-7.5 acc. IEC/EN 60715) as shown in Fig. I on the mounting plate, horizontal mounting
position, input terminals on top, respect the minimum distance to other units (see Fig. I)
2. Snap on DIN rail as shown in Fig. II
2) Lift it downward until it hits the stop
3) Press against the bottom front side for locking
Shake the unit slightly to check the locking
3. Remove the unit from the DIN rail as shown in Fig. III. Use a screwdriver for the unlocking.

Electrical connection:

Input side [INPUT 1 + - / INPUT 2 + -]:
Connect the input terminals (Fig. V ), stripping length of the cable – see technical data.
For channel 1 left-hand input terminals + -, for channel 2 right-hand input terminals + -.
Output side [OUTPUT + + - -]:
Rate the lines for the maximum output current or provide a separate fuse protection.
We recommend to choose the cable cross section as large as possible in order to minimize voltage drops.
Observe the polarity.
Operating/Function:
Parallel operation, true redundancy: (see Fig. IV)
Redundant circuits are suitable to increase the operational reliability in case of errors (e.g., wrong wiring, blow of the fuses in
supply of all consumers will be taken over by the second, redundant supply circuit. For this reason, the power supply units to
be connected in parallel are dimensioned in such a way that the total current requirement of all consumers can be completely
covered by one power supply unit, and the output circuits are decoupled by means of the redundancy unit CP-A RU, as shown
in Fig. IV.
