The secondary DC connection is effected through two coloured connection jacks.
For the switched-mode power supply SPS 1560 PFC up to 5A can be collected at
the front side and up to 60A at the rear.
The mains power supply is cooled via a temperature-controlled fan. For this reason,
make sure there is an adequate air circulation and lateral distance to obstacles.
The mains power supply is equipped with an overload protection circuit. This circuit
is activated when the maximum permissible current is exceeded due to an overload
or short circuit. The red indicator is the overload indicator. If it lights up, the consu-
mer must be disconnected from the mains power supply to avoid damage to the
switched-mode mains power supply.
Taking the Device into Operation
General Notes
The two switched-mode mains power supply units are not chargers. To charge bat-
teries, use suitable chargers with a charging current cut-off.
Connecting the Power Cable
• Connect the provided shockproof power cable to the power connector (12, female)
of the mains power supply. Make sure it is plugged properly.
• Connect the power cable to a shockproof mains socket with protective grounding.
Setting the Desired Output Voltage
• Make sure that there are no consumers connected to the mains power supply.
• Switch on the mains power supply at the power switch (1). The power indicator (2)
should light up.
• Now use the DC control (6) to set the desired output voltage. The setting can be
checked on the display (9).
Setting the Fixed Voltage of 13.8 V (only SPS 1525/1540 PFC)
• Make sure that there are no consumers connected to the mains power supply.
• Switch on the mains power supply at the power switch (1).

Replacing the Fuse (only for SPS
1525/1540 PFC)
If it is no longer possible to switch on the mains power supply, the mains fuse has
probably tripped.
Proceed as follows to replace the mains fuse:
• Switch off the mains power supply and remove all
the connection and power cables.
• Use a suitable screwdriver for slotted screws to prise
out the fuse holder on the rear of the device.
• Replace the defective fuse with a new fine-wire fuse
(5 x 20 mm) of the same type and rated current,
which are as follows:
- SPS 1525 PFC: F 3.15 A / 250 V (fast blowing)
- SPS 1540 PFC: F 5 A / 250 V
(fast blowing)
• Press the fuse-link back into the fuse holder until it
snaps in properly.
Troubleshooting
By purchasing the switched-mode mains power supply you have acquired a product
that is reliable and operationally safe.
However, problems and malfunctions may occur.
For this reason we want to describe how to troubleshoot potential malfunctions:
Always heed the safety instructions!
