Safety & Warnings
The safety warnings and precautions explicitly present in the manual are as follows:
1. Ground the Instrument: The instrument chassis and cabinet must be connected to an electrical ground to minimize shock hazard. The instrument is grounded through the ground conductor of the supplied three-conductor AC power cable, which must be plugged into an approved three-conductor electrical outlet. Do not alter the ground connection, as it can lead to electric shock.
2. Do Not Operate in an Explosive Atmosphere: The instrument should not be operated in the presence of flammable gases or fumes, as this constitutes a safety hazard.
3. Keep Away from Live Circuits: Instrument covers must not be removed by operating personnel. Component replacement and internal adjustments should only be made by qualified maintenance personnel. The power cord should be disconnected before removing instrument covers and replacing components, as dangerous voltages may exist even with the power cable removed.
4. Do Not Service or Adjust Alone: Internal service or adjustment should not be attempted unless another person capable of rendering first aid and resuscitation is present.
5. Do Not Substitute Parts or Modify the Instrument: Substitute parts should not be installed, and unauthorized modifications should not be performed. The instrument should be returned to B&K Precision for service and repair to ensure safety features are maintained.
6. Warnings and Cautions:
– A WARNING statement highlights a procedure, practice, or condition that could result in injury or death if not followed correctly.
– A CAUTION statement highlights a procedure, practice, or condition that could result in damage to or destruction of part or all of the product.
Specific warnings include:
– Do not alter the ground connection to avoid electric shock.
– Disconnect the power cord before removing covers to avoid electrical shock hazard. Servicing should be referred to qualified personnel.
Specific cautions include:
– Check the rear panel AC line voltage indicator before connecting the line cord to the AC mains to avoid destroying AC line fuses. Replace fuses only with those of the specified voltage and current ratings for continued fire protection.
– Follow proper procedures for handling, storing, and transporting parts and subassemblies containing ESD-sensitive components to avoid damage from electro-static discharge (ESD).
