Read this first!
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 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 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 Class 2. The housing is rated as IP54 according to 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 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 to the mains systems described above. Keep the following
minimum installation clearances: 0mm on top, 30mm on the bottom, 15mm on the
front and 0mm 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. 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 circuits and can supply any kind of load, 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 are according to settings. Contact ratings: 60Vdc 0.3A, 30Vdc 1A, 30Vac 0.5A for resistive loads. The device has 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 a percentage value.
100% equals an output power of 300W. LEDs up to and including 100% are green,
and 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. By 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 is 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 the positive output pole, Pin 3 for the negative output pole,
and Pin 2 and 4 are not connected.
