7. INSTALLATION
The devices must not be installed in environments where the following situations are present:
¾ Temperature and humidity outside the range stipulated in the data plate. Frequent and sudden
changes in temperature and/or humidity
¾ Direct sunlight and weathering in general
¾ High mechanical stress (vibrations and/or knocks)
¾ Sulphur and ammonia gas, smoke and salt spray that can cause corrosion and/or oxidation
¾ Presence of flammable or explosive gas
¾ Dust
¾ Devices that generate magnetic interference
Position the device inside the electrical panels, paying attention to the following:
¾ the distance between the device and the electrical power components
¾ the distance between the device and the power cables
¾ sufficient passage for the cooling air
Always comply with the laws and regulations applicable in the country where the device is installed.
Always protect the device for it to always be accessible solely by authorised personnel.
In case of malfunctions, always contact the relative distributor for the device to be repaired.
7.1 GENERAL RULES
Comply with the following recommendations during the installation process in order to prevent the device
from malfunctioning.
¾ Separate the signal cables from the power cables (it is recommended to use BELDEN 8772-type
shielded cables)
¾ Separate the cables of the analogue inputs from those of the digital inputs and the serial line cables
from the power cables (resistive as well as inductive), in order to prevent malfunction due to
electromagnetic interference
¾ Separate the power of the device from that of the other electrical components
¾ Never connect the secondary of the supply transformer to the earth
¾ The low voltage connections must have reinforced insulation
7.2 POWER SUPPLY
The power supply voltage of the devices is as follows:
¾
24Vac +10/-15%, 50/60Hz (consumption 20VA) or 20 - 36Vdc (consumption 15W) for the
programmable controllers 10 and expansion 10 DIN
¾ 24Vac +10/-15%, 50/60Hz (consumption 30VA) or 20 - 36Vdc (consumption 25W) for the 4 DIN
programmable controllers
¾ 24Vac +10/-15%, 50/60Hz (consumption 10VA) or 20 - 36Vdc (consumption 10W) for the 4 DIN
expansion.
Be careful to always comply with the following recommendations:
¾ Never use power that differs from that indicated as the devices may be damaged.
¾ Always use safety transformers
¾ Always separate the power of the controller from that of all the other electrical devices present in the
system.
¾ The secondary of the supply transformer of the devices must never be connected to the earth.
