WARNING
indicates that death or severe personal injury may result if proper precautions are not taken.
CAUTION
indicates that minor personal injury can result if proper precautions are not taken.
NOTICE
indicates that property damage can result if proper precautions are not taken.
If more than one degree of danger is present, the warning notice representing the highest degree of danger will
be used. A notice warning of injury to persons with a safety alert symbol may also include a warning relating to
property damage.

WARNING
Correct handling of the devices
When operating electrical devices, it is inevitable that certain components will carry
dangerous voltages.
Therefore, failure to handle the units properly can result in death or serious physical injury
as well as extensive property damage.
Only appropriately qualified personnel may work on or in the vicinity of this equipment.
Perfect, safe, and reliable operation of this equipment is dependent on proper
transportation, storage, installation and mounting.
Before installation or maintenance work can begin, the system's main switch must be
switched off and measures taken to prevent it being switched on again.
If this instruction is not observed, touching live parts can result in death or serious injury.

2.1
Device description
SITOP modular is a primary-clocked power supply for connection to a 1-phase/2-phase AC
line supply. An electronically regulated DC voltage that can be set via a potentiometer is
available at the output of the device. The output of the device is isolated, no-load proof and
short-circuit proof. The LED displays indicate the operating state. The integrated signaling
contact (for 6EP1336-3BA00 and 6EP1337-3BA00, only when using the supplementary
6EP1961-3BA10 signaling module) can be used to further process the operating state of the
device.

2.3
Potentiometer
The potentiometer ③on the front of the device is used to set the output voltage. The output
voltage is set to 24 V in the factory and can be adjusted in the range 24...28.8 V; for
example, to compensate voltage drops across long supply lines to the connected load.
Figure 2-5 Potentiometer (example of 6EP1337-3BA00)
NOTICE
Thermal overload possible
When adjusting the output voltage to >24 V, the output current must be derated by 4 %/V,
or the permissible ambient temperature must be taken into account with 3° C/V.
Note
It is only permissible to use an insulated screwdriver when actuating the
potentiometer.
For notes on actuating the potentiometer (screwdriver, torque), see Figure 2-2 Terminal data
for 6EP1333-3BA10 and 6EP1334-3BA10 (Page 10), Figure 2-3 Terminal data for 6EP1336-

Change-over switch
Figure 2-7 A/B selector switch
The two switches A and B are used to influence the output characteristic curve:
Switch
ON
OFF
A
influences the output
characteristic in the
load range
Parallel operation:
'Soft' characteristic curve (see, e.g. Figure 6-10
6EP1333-3BA10 parallel operation output
characteristic (Page 43)) for the parallel
operation of two or more devices: The output
voltage falls with increasing output current
(namely, also for the overcurrent pulse!).
This means that for full output current the
highest output voltage can normally no longer
be attained.
Single operation:
Delivery state
'Hard' characteristic curve (see, e.g. Figure 6-3
6EP1333-3BA10 single operation output
characteristic (Page 41)) for normal operation
(single operation): The output voltage is
independent of the output current.
B
influences the output
characteristic in the
overload range
Latching shutdown:
If the output current rises above the rated value
and above the current limit, the device reduces
the output voltage (see, e.g. Figure 6-14
6EP1333-3BA10 latching shutdown output
characteristic (Page 44)). If the output voltage
falls below 20 V, the device shuts down
latching, the red LED lights up. This limit
voltage of 20 V is independent of the set output
voltage. The 'Short-time overload current'
feature is not available in this operating mode.
To also permit the uploading of large
capacitances in this operating mode at the
output, a shutdown is performed during the first
10 s after power on or remote on in conjunction
with the non-latching signaling module. During
these first 10 s, the device responds for
overload as if the switch is OFF.
Constant current:
Delivery state
If the output current rises above the rated value
and above the current limit, the device reduces
the output voltage. The yellow LED lights up if
the output voltage falls below 20 V.
Delivery state: A - OFF; B - OFF

Selector switch for the input voltage range for 6EP1333-3BA10 (24 V/5 A) and 6EP1334-
3BA10 (24 V/10 A)
Figure 2-8 Voltage selector switch (example, 6EP1334-3BA10)
The selector switch as delivered is in the 230 V position. It must be moved to the appropriate
position for operation in the 120 V range. The selector switch can only be actuated in the de-
energized state.
To switch the input voltage range for 6EP1336-3BA00 (24 V/20 A) and 6EP1337-3BA00
(24 V/40 A) to 120 V, a wire jumper must be connected to the input terminal, Jump
120 V AC. This must be dimensioned as for the power supply cable with regard to cross-
section and insulation. The length must not exceed 100 mm.
