gefran GFW-Xtra Quick Manual

INSTALLATION AND CONNECTION
This section contains the instructions needed for correct installation of GFW modular power controller
on the machine/host system control panel and for correct connection of the power supply, inputs,
outputs and interfaces.
Carefully read the following warnings before installing the instrument!
Disregard of such warnings could create electrical safety and electromagnetic compatibility problems, as
well as void the warranty.
ELECTRICAL POWER SUPPLY
• the controller DOES NOT have an On/Off switch: the user must install switch/isolator conforming to safety
requisites (CE mark) to cut off the power supply up-line of the controller.
The switch must be installed in the immediate vicinity of the controller in easy reach of the operator.
A single switch can be used for multiple devices.
* the earth connection must be made with a specific lead
• if the product is used in applications with risk of harm to persons or damage to machines or materials, it
MUST be equipped with auxiliary alarm devices.
It is advisable to provide the ability to check for tripped alarms during regular operation.
NOTES ON ELECTRICAL SAFETY AND ELECTROMAGNETIC COMPATIBILITY:
CE: Conformity EMC (electromagnetic compatibility) conformity) in compliance with Directive 89/336/
CEE and following modifications. Series GFW are mainly intended for industrial use, installed on panels or
control panels of production process machines or systems.
For purposes of electromagnetic compatibility, the most restrictive generic standards have been adopted, as
shown on the table.
LV (low voltage) conformity in compliance with Directive 2006/95/CE.
EMC conformity has been verified with the connections indicated on table 1 (see user's manual).
RECOMMENDATIONS FOR CORRECT INSTALLATION FOR PURPOSES OF EMC
Instrument power supply
• The power supply for the electronic instrumentation on the panels must always come directly from a
cut-off device with fuse for the instrument part.
• Electronic instrumentation and electromechanical power devices such as relays, contactors, solenoids,etc.,
MUST ALWAYS be powered by separate lines.
• When the power supply line of electronic instruments is heavily disturbed by switching of thyristor power
groups or by motors, you should use an isolation transformer only for the controllers, grounding its sheathing.
• It is important for the system to be well-grounded:
- voltage between neutral and ground must not be > 1V
- Ohmic resistance must be < 6Ω;
• If the grid voltage is highly unstable, use a voltage stabilizer.
• In proximity of high-frequency generators or arc welders, use adequate grid filters.
• The power supply lines must be separate from instrument input and output lines.
• Supply from Class II or from limited energy source
Input and output connections
Before connecting or disconnecting any connection, always check that the power and control cables are iso-
lated from voltage.
Appropriate devices must be provided: fuses or automatic switches to protect power lines.
• Connected outside circuits must be doubly isolated.
• To connect analog inputs, strain gauges, linears, (TC, RTD), you have to:
- physically separate the input cables from those of the power supply, outputs, and power connections.
- use braided and shielded cables, with sheathing grounded at a single point.
Installation notes
- Moreover, the applications with solid-state units require a safety automatic switch to section the load power
line.
To ensure the high reliability of the device, it is necessary to install it properly inside the panel so to obtain
an adequate thermal exchange.
Fit the device vertically (maximum angle 10° to the vertical axis)
• Vertical distance between a device and the panel wall >100mm
• Horizontal distance between a device and the panel wall at last 10mm
• Vertical distance between a device and the next one at last 300mm.
• Horizontal distance between a device and the next one at last 10mm.
Check that the cable holder runners do not reduce these distances, in this case fit the cantilever units opposite
the panel so that the air can flow vertically without any obstacles.
• Dissipation of device thermal power with effects on installation room temperature.
• Thermal power dissipation with limits on installation room temperature.
• Requires exchange with external air or an air conditioner to transfer dissipated power outside the panel.
• Maximum limits of voltage and derived power of transients on the line, for which the solid state power unit
contains protective devices (based on the model).
• Presence of dispersion current in GFW in non-conducting state (current of a few mA due to RC Snubber
circuit to protect ).
GEFRAN S.p.A. assumes no liability for any damage to persons or property deriving from
tampering, from incorrect or improper use, or from any use not conforming to the characteristics
of the controller and to the instructions in this User Manual.
This device conforms to European Union Directive 2004/108/CE e 2006/95/CE with refe-
rence to generic standards: EN 60947-4-3 (product) EN 61010-1 (safety)
