SAFETY SUMMARY

The following general safety precautions must be observed during all phases of operation of this power module. Failure to comply with these precautions or with specific warnings elsewhere in this guide violates safety standards of design, manufacture, and intended use of the power module. Agilent Technologies assumes no liability for the user’s failure to comply with these requirements.

GROUND THE POWER MODULE.

When installed in a properly wired mainframe, this product is a Safety Class 1 instrument (provided with a protective earth terminal). To minimize shock hazard, the mainframe must be connected to an electrical ground. The mainframe must be connected to the ac power supply mains through a three-conductor power cable, with the third wire firmly connected to an electrical ground (safety ground) at the power outlet. Any interruption of the protective (grounding) conductor or disconnection of the protective earth terminal will cause a potential shock hazard that could result in personal injury.

DO NOT EXCEED INPUT RATINGS.

The mainframe is equipped with a power line filter to reduce electromagnetic interference and must be connected to a properly grounded receptacle to minimize electric shock hazard. Operation at line voltages or frequencies in excess of those stated on the line rating label may cause leakage currents in excess of 5.0 mA peak.

DO NOT OPERATE IN AN EXPLOSIVE ATMOSPHERE.

Do not operate the power module in the presence of flammable gases or fumes.

BEFORE APPLYING POWER.

Verify that the power module line voltage switch is set to match the available line voltage.

SAFETY SYMBOLS.

Instruction manual symbol: the product will be marked with this symbol when it is necessary for the user to refer to the instruction manual (refer to Table of Contents) .

Indicates hazardous voltages.

Indicate earth (ground) terminal.

The WARNING sign denotes a hazard. It calls attention to a procedure, practice, or the like, which, if not correctly performed or adhered to, could result in personal injury. Do not proceed beyond a WARNING sign until the indicated conditions are fully understood and met.

The CAUTION sign denotes a hazard. It calls attention to an operating procedure, or the like, which, if not correctly performed or adhered to, could result in damage to or destruction of part or all of the product. Do not proceed beyond a CAUTION sign until the indicated conditions are fully understood and met.

Power modules that appear damaged or defective should be made inoperative and secured against unintended operation until they can be repaired by qualified service personnel.
