1.4 Safety Considerations
Potential safety hazards exist unless proper precautions are observed when working
with this unit. To ensure safe operation, the user must follow the information, cautions
and warnings provided in this manual as well as the warning labels placed on the unit.
1.4.1 High Voltage Hazards
High Voltage for the purpose of this section is any voltage in
excess of 30 volts. Voltages above this value can be hazardous
and even lethal under certain circumstances. Care should be tak-
en when working with devices that operate at high voltage.
• All probes and tools that contact the equipment should be
properly insulated to prevent the operator 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.
1.4.2 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 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 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.
