Read carefully the following directions
INFORMATIVE NOTES. Before the installing, the consultation of these instructions is compulsory. For the sake of
clarity, the present manual doesn't contain all the detailed information about all the typologies of products and can't
cover every single and possible example of installation, operation or maintenance. The electric power supplies, object
of this manual, hereinafter also called products, can only be installed by qualified and authorized personnel who knows
and respects the technical standards as well as all the general current standards and rules related to this product
typology. The power supplies of this manual are for use with single-phase mains voltage. Their perfect and safe
operation requires proper transportation and storage such as assembly and installation performed in a workmanlike
manner.
USE AND INSTALLATION NOTES. For the technical descriptions such as for the dimensional and environmental
characteristics of the products, please refer to the table A of this manual and to the data indicated on the product label
(1). These products are not for external use. They are only suitable for their use in Overvoltage Category II (Overvoltage
Category III for the products which comply with the standard EN60335-1). They are for installation and must be placed
inside a protective self-extinguishing case that must comply with the safety standard indicated on the label (1). The
products must not be used in different environmental conditions and work ranges than the ones indicated on the label
(1). The label of the products reports the following data : the part number such as the electrical input and output
characteristics, the maximum operating temperature, the production batch and the applied safety standards. The
products must be installed vertically to let the clamping spring (2) show downwards (see table B). The holes and the
tabs of aeration of the products must not be covered. Keep a free space under and over the products to allow a free air
circulation, necessary for a correct heat exchange (table B). For the DIN-rail mounting, please refere to the table C.
Before making the installation, make sure that the power was turned off and that the input and output clamps, that are
identifiable on the product label (1) or through indications printed directly on the case, are correctly positioned. For the
standard products in Insulation Class II, the hearth connection is not foreseen. The products with a hearth clamp must
be connected to the ground. For the connection of the products to the AC mains, use cables and derivations with a
section that does not exceed a current density of 4A/mm2 and add the right terminals. Make sure that all the terminal
screws are tightly fastened in the clamps, being careful not to exceed the tightening torque indicated in the table A.
The input cables (AC mains) must be held through an insulated cable tie at 1.5 cm from the clamp output. Connect to
the AC mains supply each input pole by a readily accessible all-pole mains switch to provide a full disconnection under
the Overvoltage Category II (Overvoltage Category III for the products, which comply with the standard EN60335-1).
We recommend to protect the electrical installation through a surge absorber or a similar device. For the removal from
the DIN-rail (see table D), make sure the power was turned off, then remove the wiring from the clamps and insulate it
correctly.
PARTICULAR ENVIRONMENTAL CONDITIONS. The power supplies of this manual are for use in altitudes up to
2000 meters.
PRECAUTIONS AND CAUTIONS. Risk of electric shocks or flames. (The negligence can cause death, serious injuries
or damage the ownership). Do not connect the power supply with a not specified input source. Do not damage or crush
the input wiring. Do not install or connect the power supply, while it is on. Do not connect the output clamps to the AC
mains. Do not damage or crush the input wiring. Do not short-circuit the the input and output wiring. Do not alter, open
or perforate the power supply. Keep the power supply and the AC wires away from moisture or dust.
PROHIBITIONS. Do never install the power supply in one of the following places ; malfunctions, electric shocks or fire
can occur: where not authorized and not qualified personnel has access. Places that are exposed to very low
temperatures, under direct sunlight, near devices that change temperature, in front of air conditioners, inside a
refrigerated area, etc... . Places that are exposed to humidity or extreme condensation, like bath rooms, cellars,
greenhouses, etc.... Places that are exposed to specific environmental conditions, like dust, oil, chemicals, salt, etc... .
Places exposed to continuous vibrations or impacts. Places exposed to warm stream or smoke (near heating
equipments or cooking surfaces). Outdoors or in the rain.
DISPOSAL AND RECYCLING OF THE PRODUCTS. For the disposal of the products, follow the guidance of local
authorities. The products used, must be properly collected and recycled. This helps to minimize the amount of waste
and the negative impact that some elements can have on human health and on the environment.
