(EN) 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
1) Tilt the unit slightly upwards and fit the unit on the DIN rail
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 choosing 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 used to increase the operational reliability and eliminate power supply outages. Events that can cause a
power supply failure include: incorrect wiring, blown fuses, or failure of a single power supply. If a fault event occurs (called initial
fault) in the first power supply circuit, power to all loads is then supplied by the second, redundant power supply. For this reason,
both power supplies must be sized to handle the total current requirement of all loads. The primary and the redundant power
supplies are decoupled from one another by the CP-A RU unit, as shown in Fig. IV.
