Mounting:
1. Fasten the DIN-rail (TS35/15 or TS35/7,5 acc. EN 50022) as shown in Fig. I on the mounting plate, horizontal
mounting position, input terminals on bottom, 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 screw driver for the unlocking.
Electrical connection:
Input side [L, N,
Set the front-face „INPUT VOLTAGE SELECTOR" (CP-S 24/10.0, CP-S 24/20.0 - see Fig. I) in desired position.
Connect the input terminals L, N,
The non-fused earth conductor must be connected (class of protection I).
Actuate the plug connector (CP-S 24/5.0, CP-S 24/10.0) only when the power is off. Cable cross sections, torque
etc. - see technical data. The installation must be executed acc. EN 60950, provide a suitable disconnecting
device (e.g., line protection switch) in the supply line.
Fuse protection of the input side - see technical data.
Output side [L+, L+, L-, L-]:
Rate the lines for the maximum output current or provide a separate fuse protection.
Fuse protection of the output side - see technical data. We recommend to choose the cable cross section as large
as possible in order to minimize voltage drops. Observe the polarity.
Actuate the plug connector (CP-S 24/5.0, CP-S 24/10.0) only when the power is off. The power supplies are
overload, short-circuit and open-circuit stable (see characteristic curve). The secondary side of the power supplies
is electrically isolated from the input and internally not earthed (SELV) and can therefore be earthed by the user
according to the needs with L+ or L- (PELV).
Operating/Function:
Operational status indication: The green LED „OUTPUT OK" (Fig. I) is lightening during operation.
Parallel operation: In order to increase capacity and to enable redundancy, devices of the same type can be
connected in parallel. For a symmetric current distribution it is advisable to execute the line connections with the
same cross sections and same lengths.
Parallel operation, increased capacity: (see Fig. IV)
For n parallel connected devices, the output current can be increased to n x I
It is advisable to use parallel connection if a power supply unit does not cover the current requirement of the most
powerful consumer. Otherwise the consumers should be spread among individual devices independent of one other.
A maximum of 5 devices of the same type can be connected in parallel.
Parallel operation, redundancy: (see Fig. V)
Redundant circuits are suitable to increase the operational reliability in case of errors (e.g., wrong wiring, blow of the
fuses in the primary circuit, failure of single devices). If a fault occurs in the first power supply circuit (called initial
fault), the power 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.
