FPT500.241-010-108 Installation Manual
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.
Intended Use
This indoor use device is intended for commercial use, such as in industrial control, process control,
monitoring, measurement or the like.
Do not use this device in equipment, where malfunctioning may cause severe personal injury or
threaten human life without additional appropriate safety devices, that are suited for the end-
application.
If this device is used in a manner outside of its specification, the protection provided by the device may
be impaired.
Do not connect the negative potential of the output to PE outside the unit.
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 a
s “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 an 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 mains systems description above.
Keep the following minimum installation clearances: 50mm on top and bottom, 10mm on the front and
10mm left and right side.
The device is designed, tested and approved for branch circuits up to 20A (UL) and 32A (IEC) without
additional protection device. 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 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 circuit and can supply any
kind of loads, 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 an 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 bargraph and push-buttons:
The LED bar has two functions included. In normal operation, the LED bar displays the actual output
power as percentage value. 100% equals an output power of 500W. LEDs up to and including 100%
are green, 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 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 negative
output pole.
