1.7 Safety Considerations
Potential safety hazards exist unless proper precautions are observed when working
with this unit. To ensure safe operation, users must follow the information, cautions
and warnings provided in the manual, and the warning labels placed on the unit itself.
1.7.1 High Voltage Hazards
High Voltage for the purpose of this section is any voltage in excess of 30 volts. Volt-
ages above this value can be hazardous and even lethal under certain circumstances.
Care should be taken when working with devices that operate at high voltage.
•
All probes and tools that contact the equipment
should be properly insulated to prevent the opera-
tor from coming in contact with the voltage.
•
The work area should be secure and free from non-
essential items.
•
Operators should never work alone on high voltage
devices. There should always be another person
present in the same work area to assist in the
event of an emergency.
•
Operators should be familiar with procedures to employ in the event of an
emergency, i.e., remove all power, CPR, etc.
An AC powered unit will have 115 VAC or 230 VAC entering through the AC power
connector. Caution is required when working near this connector, the AC circuit break-
er, or the internal power supply.
1.7.2 High Current Hazards
Many high power devices are capable of producing large
surges of current. This is true at all voltages, but needs to
be emphasized for low voltage devices. Low voltage
devices provide security from high voltage hazards, but
also require higher current to provide the same power.
High current can cause severe injury from burns and
explosion. The following precautions should be taken on
devices capable of discharging high current:
•
Remove all conductive personal items (rings, watches, medals, etc.)
•
The work area should be secure and free of non-essential items.
•
Wear safety glasses and protective clothing.
•
Operators should never work alone on high risk devices. There should
always be another person present in the same work area to assist in the
event of an emergency.
