General Installation Rules - gefran 650 Installation And Instruction Manual

Attention! The devices described in this manual must be installed by trained personnel in conformity to current laws
and regulations, following all of the instructions in this manual.
Before installing, check that the controller is in perfect condition and was not damaged in shipment. Make sure that
the package contains all of the accessories listed on the accompanying document, especially the gasket and the
fastening brackets.
Check that the order code matches the configuration required for the intended application (supply voltage, number
and type of inputs and outputs). See Chapter 10 - Ordering code - to check the configuration corresponding to
each order code.
Attention! If even one of the requirements mentioned above (trained technician in, device in perfect condition,
correct configuration) is not satisfied, interrupt the installation and contact your Gefran dealer or Gefran Customer
Service.

General installation rules

The controller is designed for permanent indoor installation.
It must be mounted on electrical panels or on panels con-
trolling machines or production process plants that are able
to protect the exposed terminals on the rear of the controller.
Attention! DO NOT install the controller in a po-
tentially inflammable or explosive atmosphere.
It can be connected to elements that work in such
atmospheres only by means of appropriate interfa-
ces that conform to safety regulations in force in the
country of installation.
Attention! the controller is used in applications with
risk of harm/damage to persons/property, it MUST
be connected to dedicated alarm devices.
It is advisable to provide the possibility, during nor-
mal functioning of the controller and of the system
or equipment that it controls, of checking whether
any alarms have tripped.
The controller must be installed in a location that is not
subject to sudden temperature changes or to freezing or
condensation, and no corrosive gases must be present.
The controller can work in Pollution Degree 2 environmen-
ts (presence of non-conductive dust, only temporarily con-
ductive due to possible condensation).
Do not allow scrap or metal particles from machining or con-
densation products to reach the device.
The controller is sensitive to strong electromagnetic fields.
Do not position it near radio devices or other equipment that
may generate electromagnetic fields, such as power contac-
tors, relays, thyristor power units (especially phase angle),
motors, solenoids, transformers, high-frequency welders,
etc.

2. INSTALLATION
2.1.2.
For correct installation, respect the dimensions of each hole
and the distance between adjacent holes shown in the figu-
res for each model ("Figure 2 – 650 drilling dimensions and
templates" on page 14, "Figure 4 – 1250 drilling dimensions
and templates" on page 16, "Figure 6 – 1350 drilling dimen-
sions and templates" on page 18).
2.1.3.
The front of the controller has an IP65 protection index, so
the device can be installed without problems in rooms that
are very dusty or subject to splashing water provided:
•
•
•
•
Drilling dimensions
Attention! The support on which the operator panel
is mounted must:
• be sufficiently rigid and robust to support the
device without bending during use;
• be from 1 to 4 mm thick to allow the device to
be fastened with the supplied bracket.
Protection against infiltration of dust
and water
the housing in which the device is inserted is dust-tight
and watertight;
the support on which the device is installed is perfectly
smooth and without undulations on the front;
the hole on the support scrupulously respects the spe-
cified drilling dimensions;
the device is fully tightened to the support to ensure that
the gasket inserted between the device and the panel is
watertight
Attention! If not adequately protected, the con-
troller has an IP20 protection index (rear container
and terminal board.
