1-3. Fuse Protection The Model 4600A uses two internal fuses, one to protect the main power supply from an over current condition and other protects the battery option from receiving an excessive charging current. Both fuses are the same type: 5 X 20mm, 250VAC, 1A slow-blo fuse. If either fuse is blown, it may indicate a problem with the internal power supply circuits. -
Page 8: Rack Mounting
1-5. Rack Mounting An optional kit is available for mounting the 4600A in a standard 19" equipment rack. This is listed in Section 3. Follow the installation instructions included with the option. If the 4600A is to be transported while mounted in a rack, it should be supported so as to prevent upward or downward movement. -
Page 9: Safety Precautions
Operators should be aware of general safety precautions for working with hazardous voltages and must always heed the following precautions: 1. Ensure that the 4600A is properly earth grounded either through its 3-wire power cord or via its rear panel ground terminal. When battery power is used without out power cord, you must connect rear panel ground terminal to earth ground. -

±500VDC or peak AC (relative to earth ground). Voltages greater than this may damage the unit. The other measurement terminal on the 4600A is the BNC style HV probe input terminal. The 4600A is calibrated to a specific HV probe. The probe is identified with a serial number tag which should match the serial number of the main 4600A unit. -

This may be seen as a condition in which the 4600A will not respond to any input in any range, and the display may wander around aimlessly. This condition is temporary and will correct itself within 30 seconds after removal of the input voltage. -
Page 15: Section V Routine Maintenance
_______________________________________________________________ 5-1. General This section provides general maintenance information and a procedure for calibrating the voltmeter. The Model 4600A should be calibrated on a routine basis (every 12 months is recommended) to ensure continued accuracy. 5-2. Required Test Equipment The test equipment listed below or its equivalent is required for performance of the calibration procedure. -
Page 16: Battery Replacement Instructions
5-4. Battery Replacement Instructions The rechargeable battery assembly used in the 4600A consists of three PCB mounted 2-volt cells. The cells are of the sealed lead-acid type, and should provide years of trouble-free service. The replacement battery assembly is available as Vitrek Stock 947-1000. The battery assembly should always be replaced as a complete assembly.
