Orbit Network. Note: Throughout this manual the Orbit System is referred to as requring a 5V power supply. For any applications, actual voltages or power supplies may be within the 4.75 to 5.25V range according to configuration. PSIM-AC and PSIM-DC has a nominal 5.1V output no load voltage. -
Page 5: Safety Information
This symbol indicates where applicable cautionary or other information is to be found. LDN-PS CAUTION: Power Source. The PSIM-AC unit should be connected to the mains supply via a suitable lead with a IEC320 socket. The user should fuse this connection with a suitable fuse. - Page 6 A protective ground connection by way of the grounding conductor in the power lead is essential for safe operation. LDN-PS CAUTION This equipment contains no user serviceable parts. This equipment must be returned to original supplier for all service and repair.
