SCS PSRD Switching Power Supply

Switching power supply
INSTALLATION

Cut the power.

The power supply must be supplied with an AC mains of 230V +/- 10%, 50/60 Hz. It supplies an output voltage of 12V DC (continuous voltage). The maximum current supplied is of IA during about I minute or O,8A permanently. Should the consumption of IA be longer than I minute, the power supply would progressively get in protection and stop functioning. It would start functioning again after a few minutes. The power supply must be installed vertically on the DIN-rail to let the clamping spring show downwards. X : Minimum air gap distance between input and output cables (100 mm). Y : The input cables (the mains) must be halted through a strap isolated at 1,5 cm from t e clam output. Dl/D2 : Minimum air gap distance below and above the product : 40 mm.
Tightening torque of the clamps screws : 0,5 Nm

DANGER OF ELECTROCUTION
Read carefully the following directions
Before the installing by the user of the power supply ref. PSRD, bellow called « product or power supply », the consultation of these instructions is compulsory. The electric power supply, object of this manual, hereinafter also called product, can only be installed by qualified and authorized personnel who knows and respect the technical standards as well as all the general current standards and rules related to this product typology. The power supply of this manual is for use with single-phase mains voltage. Its perfect and safe operation requires proper transportation and storage such as assembly and installation performed in a workmanlike manner.

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). 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 (Y) 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. We recommend to protect the electrical installation through a surge absorber or a similar device. A wiring must be realized to guarantee an adequate distance between the input and output cables (table A), so to maintain the insulation between the primary and the secondary and avoid radio interferences. For the removal from the DIN- rail (see table D), make sure the power was turned off, the remove the wiring from the clamps and insulate it correctly.

PRECAUTIONS

These equipments are not suitable for use in locations where children are likely to be present. Risk of electric shocks or flames. (The negligence can cause dath, 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 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.

INTERDICTIONS

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. Do not use at an altitude exceeding 2000m

Don’t throw out-of-order products with household waste (garbage). The dangerous substances that they are likely to include may harm health or the environment. Make your retailer take back these products or use the selective collect of garbage proposed by your city.
