Warning notice system
This manual contains notices you have to observe in order to ensure your personal safety, as well as to prevent
damage to property. The notices referring to your personal safety are highlighted in the manual by a safety alert
symbol, notices referring only to property damage have no safety alert symbol. These notices shown below are
graded according to the degree of danger.
DANGER
indicates that death or severe personal injury will result if proper precautions are not taken.
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.

Potentiometer
The potentiometer ③on the front of the device is used to adjust 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: 6EP3334-8SB00-0AY0)
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 o
nly permissible to use an insulated screwdriver when actuating the potentiometer.
For information on actuating the potentiometer (screwdriver, torque), see Figure 2-4
Terminal data for 6EP1336-3BA10 (Page 12). and Figure 2-3 Terminal data for

Change-over switch
Figure 2-8 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 6-6 Output
characteristic curve 6EP3333-8SB00-0AY0 parallel
operation (Page 42)) for the parallel operation of two
or more devices: The output voltage falls with increas-
ing 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 Output characteristic curve
6EP3333-8SB00-0AY0 stand-alone op-
eration (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 6-9 Output characteristic
curve 6EP3333-8SB00-0AY0 latching shutdown
(Page 43)). 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-term overload current"
feature is not available in this operating mode.
6EP3333-8SB00-0AY0 and 6EP3334-8SB00-0AY0
are reset using power supply OFF for a minimum of
60 s or remote OFF and ON at the remote contact.
6EP1336-3BA10 is reset by switching the power sup-
ply OFF for at least 5 s.
To also guarantee that large capacitances can be
charged at the output in this operating mode, a non-
latching shutdown is not performed during the first
10 s after power ON or remote ON. 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.

Function: The device is remotely switched off when contacts 15, 16 are short-circuited

as a result of an overload, then it can be restarted using remote OFF followed by remote
ON.
