1.3Safety Precautions

The following general safety precautions must be observed during all phases of operation, service, and repair of this equipment. Failure to comply with these precautions or with specific warnings elsewhere in this manual violates safety standards of design, manufacture, and intended use of this equipment. Honeywell assumes no liability for the customer’s failure to comply with these requirements, as listed below.

1.Any interruption of the protective grounding conductor (inside or outside the instrument) or disconnecting the protective earth ground terminal is likely to make this equipment dangerous. Intentional interruption is prohibited.

2.Whenever it is likely that the ground protection has been impaired, the equipment must be made inoperative by removing AC line power, and then shall be secured against any unintended operation.

3.Ensure that only fuses with the required rated current and of the specified type (normal blow, time delay, etc.) are used for replacement. The use of repaired fuses and the short-circuiting of fuseholders must be avoided.

4.Electrical energy available at many points may result in personal injury or death if touched. Any adjustment, maintenance, and repair of the opened equipment while power is applied shall be avoided as much as possible, however some maintenance described in this manual is performed with power supplied to the equipment while protective covers are removed. When repair with power applied is unavoidable, maintenance shall be carried out only by a skilled person who is aware of the hazard involved. Do not attempt internal service or adjustment unless another person, capable of rendering first aid and resuscitation, is present.

5.Do not install substitute parts or perform any unauthorized modification to the equipment.

6.Capacitors inside the equipment may still be charged after the equipment has been disconnected from its power source, even though the equipment was designed to drain charge from the capacitors when power is removed. Do not put hands or tools in the Flashhead until the High Voltage Indicator neon lamp DS1 on the High Voltage & Trigger board is extinguished. (Refer to Figure 1-2, Page 1-3, for the location of High Voltage Indicator DS1 - do not confuse the High Voltage Indicator DS1, with the PWR ON lamp DS1.) Note that it is possible for the High Voltage Indicator DS1 to be lit even when the PWR ON lamp DS1 is off. If this happens, the energy storage capacitors C1 - C3 must be discharged before performing maintenance.
