Fuse rating: T10A 250V 2. Power supply must be secured to the chassis of the end use equipment by 4 screws, inserted into threaded holes in the mounting surface of the power supply enclosure. ( Refer to outline drwg. ). 3. Max. leakage current of the end use equipment should not exceed 3.5mA. 4. The following modules are capable of providing hazardous energy (>240VA) according to output voltage setting. Manufacturers final equipment must provide protection to service personnel against inadvertent contact with these module output terminals. If set such that hazardous energy can occur then the module terminals or connections therefore must not be user accessible. CAUTION: FUSE MUST BE REPLACED BY AUTHORIZED SERVICE PERSONNEL ONLY! CE MARK 1. EWS300P Series is intended for professional installation within host equipment and must not be used as a stand alone product. 2. CE marking, when applied to a product covered by this manual indicates compliance with the Low Voltage Directive only. SICHERHEITSHINWEISE Vor Anschluss an das Netz Aufstellanleitung beachten! 1.
