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!
CAUTION: Hot surface
The heatsinks of the power supply can reach
temperatures >65°C, depending on the load.
NOTE

QUINT4-PS/1AC/48DC/20

– The power supply is approved for the connection to TN,
TT and IT power grids (star networks) with a maximum
phase-to-phase voltage of 240VAC
– If the device is connected to the IT system, a two-pole
circuit breaker is required in the application.
– 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.
– Improper use invalidates the device protection.
– Relay contact 13/14 can be used to max. 30VAC/
24VDC.
The continuous total output power may not exceed
PN at 60°C ambient temperature and PStat. Boost at
40°C ambient temperature. Observe all the
maximum output powers for all operating
conditions.
NOTE: Damage to the Push-in connection
terminal blocks is possible
Do not plug test pins into the Push-in connection
terminal blocks. The maximum pluggable depth of
the Push-in connection terminal blocks is limited.
In addition, when the test pin is plugged in, the
unlocking button (pusher) is covered to such an
extent that unlocking is not possible or only
possible to an insufficient extent. If you do not
push the unlocking button (pusher) down
completely when you are pulling the test pin out,
then the Push-in connection terminal block will
become damaged.

6 High-voltage test (HIPOT)
This protection class I 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 AC 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 manufacturing process for the power supply, 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 1.5kVAC/2.2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 0.8kVAC/1.1kVDC
can be performed as described.
For high-voltage tests > 0.8kVAC/1.1kVDC,
the gas-filled surge arrester must be
disconnected.
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
Key
6.3.2 Disconnecting the gas discharge tube
The built-in gas discharge tube inside the device ensures
that the power supply is effectively protected against
asymmetrical disturbance variables (e.g.,EN 61000-4-5).
Each surge voltage test represents a very high load for the
power supply. Therefore avoid unnecessary loading or
damage to the power supply due to excessive test voltages.
If necessary, the gas discharge tube inside the device can
be disconnected in order to use higher test voltages.
Following successful completion of testing, please
reconnect the gas-discharge tube.
Figure 2 Disconnect gas discharge tube
To disconnect the gas discharge tube, proceed as follows:
1. Remove power from the unit.
2. Unscrew the Phillips head screw completely and keep
the gas discharge tube screw in a safe place. The gas-
discharge tube is now disconnected and is no longer
functional.
3. Perform the surge voltage test on the power supply.
4. Following successful high-voltage testing, screw the
gas discharge tube screw fully back into the power
supply.
For the relevant applicable test voltages and
insulation distances, refer to the corresponding
table (see technical data: electric strength of the
insulation section).
