5 Safety and installation notes
Symbols used
Instructions and possible hazards are indicated by
corresponding symbols in this document.
There are different categories of personal injury that are
indicated by a signal word.
The following symbols are used to indicate potential
damage, malfunctions, or more detailed sources of
information.
Safety notes and warning instructions
– Only skilled persons may install, start up, and operate
the device.
– Never carry out work when voltage is present.
– Establish connection correctly and ensure protection
against electric shock.
– Cover termination area after installation in order to avoid
accidental contact with live parts (e. g., installation in
control cabinet).
– Observe the national safety and accident prevention
regulations.
– Assembly and electrical installation must correspond to
the state of the art.
– The power supply is a built-in device and is designed for
mounting in a control cabinet.
– The IP20 degree of protection of the device is intended
for use in a clean and dry environment.
– Observe mechanical and thermal limits.
– Ensure that the primary-side wiring and secondary-side
wiring are the correct size and have sufficient fuse
protection.
– For the connection parameters for wiring the power
supply, suchas the required stripping length with and
without ferrule, refer to the technical data section.
– Use copper cables for operating temperatures of
75°C (ambient temperature 55°C)
90°C (ambient temperature 75°C).
– Protect the device against foreign bodies penetrating it,
e.g., paper clips or metal parts.
– The power supply is maintenance-free. Repairs may
only be carried out by the manufacturer. The warranty
no longer applies if the housing is opened.
– The power supply may only be used for its intended use.
This is the safety alert symbol. It is used to alert
you to potential personal injury hazards. Obey all
safety measures that follow this symbol to avoid
possible personal injuries.
WARNING
This indicates a hazardous situation which, if not
avoided, could result in death or serious injury.
CAUTION
This indicates a hazardous situation which, if not
avoided, could result in minor or moderate injury.
NOTE
This symbol together with the signal word NOTE
and the accompanying text alert the reader to a
situation which may cause damage or malfunction
to the device, hardware/software, or surrounding
property.
This symbol and the accompanying text provide
the reader with additional information or refer to
detailed sources of information.
WARNING: Danger to life by electric shock!

6 High-voltage test (HIPOT)
This protection class II power supply is subject to the Low
Voltage Directive and is factory tested. During the HIPOT
test (high-voltage test), the insulation between the input
circuit and output circuit is tested for the prescribed electric
strength values, forexample. The test voltage in the high-
voltage range is applied at the input and output terminal
blocks of the power supply. The operating voltage used in
normal operation is a lot lower than the test voltage used.
6.1 High-voltage dielectric test (dielectric strength
test)
In order to protect the user, power supplies (as electric
components with a direct connection to potentially
hazardous voltages) are subject to more stringent safety
requirements. For this reason, permanent safe electrical
isolation between the hazardous input voltage and the
touch-proof output voltage as safety extra-low voltage
(SELV) must always be ensured.
In order to ensure permanent safe isolation of the DC input
circuit and DC output circuit, high-voltage testing is
performed as part of the safety approval process (type test)
and manufacturing (routine test).
6.2 High-voltage dielectric test during the
manufacturing process
During the power supply manufacturing process, a high-
voltage test is performed as part of the dielectric test in
accordance with the specifications of IEC/UL/EN61010-1.
The high-voltage test is performed with a test voltage of at
least 1.2kVDC or higher. Routine manufacturing tests are
inspected regularly by a certification authority.
6.3 High-voltage dielectric test performed by the
customer
Apart from routine and type tests to guarantee electrical
safety, the end user does not have to perform another high-
voltage test on the power supply as an individual
component. According to EN 60204-1 (Safety of machinery
- Electrical equipment of machines) the power supply can be
disconnected during the high-voltage test and only installed
once the high-voltage test has been completed.
High-voltage tests up to 1.2kVDC can be
performed as described.
The test voltage should rise and fall in ramp form.
The relevant rise and fall time of the ramp should
be at least two seconds.

6.3.1 Performing high-voltage testing
If high-voltage testing of the control cabinet or the power
supply as a stand-alone component is planned during final
inspection and testing, the following features must be
observed.
– The power supply wiring must be implemented as
shown in the wiring diagram.
– The maximum permissible test voltages must not be
exceeded.
Avoid unnecessary loading or damage to the power supply
due to excessive test voltages.

test

For the relevant applicable test voltages and
insulation distances, refer to the corresponding
table (see technical data: electric strength of the
insulation section).

8 Mounting/removing the power
supply
8.1 Mounting the power supply unit
Proceed as follows to mount the power supply:
1. The power supply is mounted in the normal mounting
position from above onto the 35mm DIN rail (DIN EN
60715). Make sure that the integrated snap-on foot is in
the correction position behind the DIN rail (A).
2. Then press the power supply down until the integrated
snap-on foot audibly latches into place (B).
3. Check that the power supply is securely attached to the
DIN rail.
Figure 7 Snapping the power supply onto the DIN rail
8.2 Removing the power supply unit
Proceed as follows to remove the power supply:
1. Take a suitable screwdriver and insert this into the lock
hole on the integrated snap-on foot (A).
2. Release the lock by lifting the screwdriver (B).
3. Carefully swivel the power supply forward (C) so that
the lock slides back into the starting position.
4. Then separate the power supply from the DIN rail (D).
