Installation Manual
Product Description
The FPT300.246-042-101 is a stand-alone power supply for three-phase mains systems, which
provides a stabilized and galvanically separated PELV/ES1 output voltage at 4 outputs. The negative
potential of the outputs is permanently connected to PE within the unit.
The outputs fulfill the requirements for a limited power source according to NEC Class2.
The housing is rated as IP54 according IEC60529 and 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 used in a manner outside of its specification, the protection provided by the device may be impaired.
WARNING: Risk of fire or electric shock. Do not interconnect output terminals.
Installation Instructions
Install the device with the terminals on the bottom of the device. Other mounting orientations require a
reduction in output current. When installing watch out for the risk of injury from sharp edges and
assure that when installed any sharp edges on the back cannot be accessed and cannot cause injury.
The power supply is mounted on a bracket with 4 screws of size M4 ( UNC 8-32). For mounting the
bracket use screws of equal or higher strength.
The enclosure of the device provides a degree of ingress protection of IP54 when installed with all
mating connectors firmly connected. The enclosure provides no protection against spilled liquids.
The device is designed for pollution degree 2 areas in controlled environments. No condensation or
icing is allowed.
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 an external
protection. A disconnecting means shall be provided for the input of the device.
The device is designed for convection cooling without a fan. Do not obstruct airflow.
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: 0mm on top, 30mm on the bottom, 15mm on the
front and 0mm 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.
Make sure that you only use plugs and cables rated for the device output current and the required
temperature range. Follow all local and national codes for installation.
The maximum permissible ambient air temperature is +70°C (+158°F). The operational temperature is
the same as the ambient or ambient air temperature and is defined 2cm below the device.
The device is designed to operate in areas between 5% and 95% relative humidity.
Do not connect the negative potential of any output to PE.
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 inductive and capacitive loads. If capacitors with a capacitance >20mF are
connected to one output, this output might switch off after turning the unit or the output on or
connecting the load.
Do not apply return voltages from the load to the output terminals higher than 35V.
The green Status LED reports an output above 90% of the adjusted voltage of a running device and
no output tripped due to overcurrent or overtemperature.
The OUT-OK contact is closed when the Status LED is green and all outputs according settings.
Contact ratings: 60Vdc 0.3A, 30Vdc 1A, 30Vac 0.5A for resistive loads.
The device has an internal overtemperature protection. If the temperature is too high the unit shuts
down and starts automatically again after cooling off. Each output will get the same state as before the
shutdown.
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.
Do not parallel devices or outputs for higher output currents.
LED bar and push-buttons:
The LED bar normally displays the actual output power as percentage value. 100% equals an output
power of 300W. LEDs up to and including 100% are green, the LEDs above 100% are orange. With
the up and down button you can see the actual power per channel (orange LED indicates the currently
selected channel). If you press the "Set Mode" button for 3 seconds all LEDs light up briefly and one
LED stays on, showing the actual output voltage. With pressing the up or down button you can change
the set voltage to the predefined values: 24V, 24.5V, 25V, 25.5V, 26V, 26.5V, 27V and 28V as printed
aside the LEDS. The voltage is set immediately and the value stored until the next change. If no
button is pressed for 15s unit returns to the normal state the LED bar will return to show the output
power.
Mating connectors:
Use a Harting HANQ5/0 female plug to connect to the input voltage connector (X1).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.
Use a standard M12 A-coded 5 pin female plug to connect to the OUT-OK signal connector (X2).
Pin assignment for the Output OK connector (X2): Pin 1 and Pin 4 for relay contact
Use a standard M12 A-coded 5 pin male plug to connect to the output connectors (X2). Pin 1 for
positive output pole, Pin 3 for the negative output pole and the Pin 2 and 4 not connected.
