Before operating this device, please read this manual thoroughly and retain
this manual for future reference! This device may only be installed and put
into operation by qualified
personnel. If damage or malfunction should occur during operation, immediately
turn the power off and send the device to the factory for inspection. The
device does not contain serviceable parts. The information presented in this
document is believed to be accurate and reliable and may change without
notice. For any clarifications, the English translation will be used.
** WARNING
Risk of electrical shock, fire, personal injury, or death:
**
- Turn the power off before working on the device. Protect against inadvertent re-powering.
- Do not open, modify or repair the device.
- Do not use it in wet locations or in areas where moisture or condensation can be expected.
- Do not touch during power-on and immediately after power-off. Hot surfaces may cause burns.
Product Description
The FPT500.241-010-108 is a stand-alone power supply for three-phase mains
systems, which provides a stabilized and galvanically separated PELV/ES1
output voltage. The negative potential of the outputs is permanently connected
to PE within the unit.
The device is incorporated in a housing rated for IP65 and IP67, which
provides protection against electrical, mechanical, and fire hazards.
Installation Instructions
Install the device onto a flat surface with the terminals on the bottom of the
device. Other mounting orientations require a reduction in output current.
The device is designed for pollution degree 3 areas in controlled
environments.
Install the device on a large enough flat surface so that any sharp edges on
the back cannot cause injury.
The power supply is mounted on a bracket with 4 screws of size M4. For
mounting the bracket use screws of equal or higher strength.
The enclosure of the device provides a degree of ingress protection of IP65
and IP67 when installed with all mating connectors firmly connected.
The device is designed as “Class of Protection I” equipment according to IEC
61140. Do not use without a proper PE (Protective Earth) connection.
For TN, TT mains systems with earthed neutral and IT star mains systems with
insulation monitoring the device is designed for overvoltage category III
zones up to 2000m (6560ft) and for overvoltage category II zones up to 5000m
(16400ft). For TN, TT, IT delta mains systems or IT star mains systems without
insulation monitoring the device is intended for overvoltage category II zones
up to 2000m (6560ft).
The device is designed to be safe in case of a single-phase loss and does not
require external protection.
A disconnecting means shall be provided for the input of the device.
The device is designed for convection cooling and does not require an external
fan. Do not obstruct airflow and do not cover ventilation fins!
The device is designed for altitudes up to 5000m (16400ft). Above 2000m
(6560ft) a reduction in output current is required and the operation is
limited according to the mains systems described above.
Keep the following minimum installation clearances: 50mm on top and bottom,
10mm on the front, and 10mm left and right sides.
The device is designed, tested, and approved for branch circuits up to 20A
(UL) and 32A (IEC) without additional protection devices. If an external fuse
is utilized, do not use circuit breakers smaller than 6A B- or
C-Characteristic to avoid a nuisance tripping of the circuit breaker.
The maximum surrounding air temperature is +70°C (+158°F). The operational
temperature is the same as the ambient or surrounding air temperature and is
defined as 2cm below the device.
The device is designed to operate in areas between 5% and 95% relative
humidity.
Cleaning only with a damp cloth.
Functional Description
The output is electronically protected against no-load, overload, and short
circuits and can supply any kind of load, including unlimited inductive and
capacitive loads. If capacitors with a capacitance >100mF are connected, the
unit might charge the capacitor in an intermittent mode.
Do not apply return voltages from the load to the output terminals higher than
35V.
The green DC-OK LED reports an output above 90% of the adjusted voltage of a
running device.
The DC OK relay monitors the output voltage and the contact is closed when the
DC-OK LED is on.
Contact ratings: 60Vdc 0.3A, 30Vdc 1A, 30Vac 0.5A for resistive loads.
The device is equipped with over-temperature protection. In case of a high
temperature, the output shuts down and starts automatically again after
cooling off.
Do not parallel devices for higher output currents.
Do not connect the outputs of multiple devices in a series connection for
higher output voltages.
In case of an internal defect, a redundant circuit limits the maximum output
voltage to 32.5V. The output shuts down and automatically attempts to restart.
LED bar graph and push-buttons:
The LED bar has two functions included. In normal operation, the LED bar
displays the actual output power as a percentage value. 100% equals an output
power of 500W. LEDs up to and including 100% are green, and the LEDs above
100% are orange.
The second function of the LED bar is to display the set point of the output
voltage. Therefore, press the “Set Mode” button for 3s. All LEDs will be on
for a short period of time and the one, which equals the output voltage,
remains on.
To change the output voltage, press the “Set Mode” button for 1s and change
the output voltage by pressing the up or down buttons. The voltage can be set
to the following predefined values: 24V,
24.5V, 25V, 25.5V, 26V, 26.5V, 27V, and 28V as indicated by the LEDs. The DC-
OK LED means 24V.
The voltage is set immediately and the value is stored until the next change.
Without further pressing of push-buttons, the LED bar will return to output
power mode after 15s.
Mating connectors:
For the mating input voltage connector (X1) use the connector HANQ4/2 from
Harting consisting of four parts. Use order numbers 19 12 008 0429 (1x
housing), 09 12 006 3141 (1x insert), 09 32 000 6204 (4x crimp contacts) and
19 12 000 5156 (1x cable gland). Pin assignment for the input connector
(X1): Pin 1 for L1, Pin 2 for L2, Pin 3 for L3, and the Pin with the PE symbol
for PE.
For the mating DC OK signal connector (X2) use a standards M12 A-coded 5-pin
female connector.
Pin assignment for the DC OK connector (X2): Pin 1 and Pin 4 for relay
contact.
The output voltage terminal (X3) utilizes the connector HAN Q2/0 from the
company Harting consisting of three parts. Use order number 6104401263900 for
the set of all necessary parts.
Pin assignment for the output connector (X3): Pin 1 for the positive output
pole, Pin 2 for the negative output pole.
Technical Data
All values are typical figures specified at 3x 400Vac 50Hz input voltage, symmetrical phase voltages, 24V, 500W output load, 25°C ambient temperature and after a 5 minutes run-in time unless otherwise noted.
