Installation must strictly follow the national safety regulations in compliance with the enclosure, mounting, creepage, clearance, casualty, markings and segregation requirements of the end-use application. See also: Technical Information: Installation and Application. in the wiring to the phase terminal L. A second fuse in the wiring to the neutral terminal N is needed if: • Local requirements demand an individual fuse in each source line • Neutral and earth impedance is high or undefined • Phase and neutral of the mains are not defined or cannot be assigned to the corresponding terminals (L to phase and N to neutral) Connection to the system shall be made via the terminal block at the rear side of the unit according to Terminal Assignment. Important: Do not open the modules, or guarantee will be invalidated. For safety reasons it is essential to connect the FG and ACG terminals with protective earth. See also: Safety of operator accessible output circuit. A fuse is built-in in the connection from the L terminal of the unit. Since this fuse is designed to protect the unit in case of an overcurrent and does not necessarily cover all customer needs, an external fuse suitable for the application and in compliance with the local requirements should be installed Make sure that there is sufficient air flow possible for convection cooling. This should be verified by measuring the ambient temperature when the unit is installed and operated in the end-use application. The maximum specified ambient temperature TA max must not not be overriden, depending on output power and mounting method. See: Thermal Considerations and table: Allowed output power by mounting method. Mounting Methods Care should be taken that there is sufficient air convection around the power supply unit. Whenever possible, forced air cooling is recommended to obtain a higher reliability. For open frame or covered structures: a) Horizontal mounting: Use tapped holes at bottom side of the frame for fastening to the chassis. Use M3 screws with torque at less than 5 kpcm. Screw length should not damage the insulation. Air b) Vertical mounting: Holes are provided on the flange; M3 screws should be used. 09064 Air Ample spacing 09063 Upper panel with good ventilation Ample spacing Air This surface in contact with chassis side or with convection cooling Case mounted on material with good heat conduction Case side in contact with chassis Main chassis Case mounted on material with good heat conduction Fig. 19 Hoirizontal mounting Fig. 20 Vertical mounting Protection Degree The protection degree of the AC-DC converters is IP 20, exept in the vicinity ot the terminal block, where it depends on the installation.

Edition 4/4.99 11/13 SWE Series AC-DC Converters <40 Watt Benign Environment Standards and approvals Isolation The AC-DC converters correspond to class I equipment and are UL recognized according to UL 1950, UL recognized for Canada to CAN/CSA C22.2 No. 950-95 and LGA approved to IEC/EN 60950 standards. The electric strength test is performed as factory test in accordance with IEC/EN 60950 and UL 1950 and should not be repeated in the field. Melcher will not honour any guarantee claims resulting from electric strength field tests. The units have been evaluated for: • Building in, • Basic insulation between input and frame and double or reinforced insulation between input and output, based on their maximum input voltage. • Operational insulation between output and frame, • The use in a pollution degree 2 environment, • Connecting the input to an overvoltage category II circuit if >150 V or an overvoltage category III circuit if ≤150 V.

Safety of operator accessible output circuit If the output circuit of an AC-DC converter is operator accessible, it shall be an SELV circuit according to the IEC/EN 60950 related safety standards The following table shows a possible installation configuration, compliance with which causes the output circuit of the AC-DC converter to be an SELV circuit according to IEC/EN 60950 up to a configured output voltage (sum of nominal voltages if in series or +/– configuration) of 44 V. However, it is the sole responsibility of the installer to assure the compliance with the relevant and applicable safety regulations. More information is given in: Technical Information: Safety.
