FPT300.242-008-102 Installation Manual
Product Description
The FPT300.242-008-102 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 output is permanently connected to PE within the unit. 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.
Parallel connection of the output voltages of up to 3 units is possible when using 2.5mm2 litz wires on
the outputs of all units.
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 d
evice 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.
Make sure that the used connectors and cables are according the output current rating and the
required temperature range.
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 the 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 >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 feed-back
energy must be below 2.5J.
The green DC-OK LED reports an output voltage above 22V of a running device.
The red DC-NOT-OK LED reports an output voltage below 22V of a running device.
The orange OVERLOAD LED is on when the output current is higher than 15A.
The contact of the DC-OK relay is closed when the DC-OK LED is on.
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 output shuts
down and starts automatically again after cooling off.
The device is designed to deliver an output power of 450W for up to 60s with nominal output voltage.
The time between pulses should be at least three times longer than the pulse itself.
The device is designed to deliver an output power of 600W for up to 1s with nominal output voltage.
The time between pulses should be at least seven times longer than the pulse itself.
Up to three devices can be paralleled to increase the output power. Current sharing is achieved by
regulating the output voltage to the set value at nominal load and approximately 4% more at no load.
Energize all units at the same time. It might be necessary to cycle the input power (turn-off for at least
five seconds), if the output was in overload or short circuit.
