Caution! The installation of the devices described
in this manual must be carried out by qualified
technicians, following current laws and regulations
and in accordance with the instructions given in
this manual.
Before installation, check that the controller is
intact and has not been damaged during trans-
port. Also ensure that the package contains all the
accessories listed in the documentation.
Check that the order code corresponds to the
configuration required for the intended use of the
controller (rated supply voltage and current, num-
ber and type of inputs and outputs). See chapter
"8. Order codes" to check the configuration for
each order code.
2.1.
Installing the controller
2.1.1.
General installation rules
The GPC Advanced Power Controller is designed for per-
manent indoor installation. It must be installed in electrical
panels or in the control panels of machines or production
process systems, where the exposed terminals will be
protected.
Caution! The Advanced Power Controller must
NOT be installed in hazardous environments (flam-
mable or explosive atmospheres). It may only be
connected to elements operating in such environ-
ments by means of suitable types of interfaces, in
conformity with the applicable safety standards.
Caution! If the Advanced Power Controller is used
in applications with risk of damage to persons
or property, it must be used in conjunction with
dedicated alarm devices. We recommend allowing
the possibility to check alarm operation also during
normal operation of the controller and the system
or equipment being monitored.
The Advanced Power Controller must not be installed
where sudden changes in temperature, freezing or conden-
sation can occur or where corrosive gases are present.
The Advanced Power Controller can operate in environ-
ments with a pollution degree 2 rating.
Caution! Unless adequately protected, the pro-
tection rating of the Advanced Power Controller is
IP20.

Caution! If even one of the above-mentioned
requirements (qualified technician, device intact,
configuration compatible with needs) is not met,
suspend installation and contact your Gefran deal-
er or Gefran Customer Service.
2.1.2.
Positioning and minimum
ventilation space
To ensure the high reliability of the device, it is essential to
install it properly inside the electrical panel so as to ensure
an adequate exchange of heat.
Mount the device vertically (maximum 10° inclination from
the vertical plane).
The temperature of the compartment containing the Con-
troller must not exceed 50°C for models with rated current
from 400 A to 600 A and 40°C for models with rated current
from 40 A to 300 A (for higher temperatures, see the derat-
ing curves).
Never obstruct the ventilation grills.
Ensure the minimum clearance for adequate air circulation:
•
Vertical distance between a device and the panel wall
>100 mm
•
Horizontal distance between a device and the panel
wall at least 10 mm
•
Vertical distance between one device and another at
least 300 mm.
•
Horizontal distance between one device and another at
least 10 mm.
See "Figure 8 - GPC minimum ventilation spaces".
Ensure that these distances are not reduced by cable duct-
ing. If necessary, mount the units away from the panel wall
so that the air can flow vertically without obstruction.
2.1.3.
Fixing to the electrical panel
The fixing to the electrical panel is made via the slots at the
top and bottom of the controller.
Use M5 screws or bolts or equivalent.
The following illustrations show the drilling templates to be
used for fixing the controller, depending on the model and
configuration (single-phase, two-phase or three-phase).
All measurements are in mm.
