Safety & Warnings
The safety warnings and precautions in the manual include:
1. Ground the instrument to minimize shock hazard. The instrument chassis and cabinet must be connected to an electrical ground through the supplied three-conductor AC power cable. Do not alter the ground connection.
2. Do not operate the instrument in an explosive atmosphere, such as in the presence of flammable gases or fumes.
3. Keep away from live circuits. Instrument covers should not be removed by operating personnel, and component replacement and internal adjustments should be made by qualified maintenance personnel only. Disconnect the power cord before removing covers and replacing components.
4. Do not service or adjust the instrument alone. Ensure another person capable of rendering first aid and resuscitation is present.
5. Do not substitute parts or modify the instrument. Unauthorized modifications can compromise safety features.
6. Follow warnings and cautions throughout the manual to avoid injury, death, or damage to the product.
7. Hazardous voltages may be present when covers are removed. Qualified personnel must use extreme caution when servicing the equipment.
8. Ensure the product is set to match the line voltage before applying power, and ensure all power ground lines are properly connected.
9. Always de-energize AC input power before connecting or disconnecting the power cable, and switch off the AC source mains before connecting or disconnecting loads.
10. Authorized service technicians should guard against electrical shock risks during open cover checks and allow time for discharge of storage elements before opening the cover. Use safety glasses during open cover checks.
11. Replace fuses with those of the specified voltage and current ratings only.
