Installation Manual  Type ：Enclosed Type Switching Power Supply (Families: CSP, DPU, ENP, ERP, G3, HDP, HEP, HRP, HRP-N, HRP-N3, HRPG, HSP, LRS, MSP, NED, NEL, NES, NSP, PSP, PSPA, QP, RS, RSP, RST, SE, SP, SPV, TP, UHP, USP)  Introduction Enclosed type switching power supplies possess a metal or plastic case for covering their internal PCB and will be installed inside the case of the end system. Mean Well’s enclosed type power supplies include 2 different groups of power supplies, with built-in fan and without built-in fan, depending on their rated power or design concept.  Installation （1 ）Before any installation or maintenance work, please disconnect your system from the utility. Ensure that it can’t be re-connected inadvertently! （2 ）Keep enough insulation distance between mounting screws and internal components of power supplies. Please refer to case drawing on specifications to receive the maximum length of mounting screw. （3 ）Mounting orientations other than standard orientation or operate under high ambient temperature may increase the internal component temperature and will require a de-rating in output current. Please refer to the specification sheets to receive the optimum mounting position and information about the de-rating curve. （4 ）Fans and ventilation holes must be kept free from any obstructions. Also a 10-15 cm clearance must be kept when the adjacent device is a heat source. （5 ）Input and Output terminal Terminal Screw Suggested Screw Size Series
