1. INTRODUCTION
The phase rotation indicator is a handheld instrument designed to detect
the rotary field of three-phase systems.
2. SYMBOLS
The following symbols appear on the Motor and Phase Rotation indicator
or in this manual.
Risk of electric shock
Risk of Danger, Important information see manual.
Hazardous Voltage.
Equipment protected by double or reinforced insulation
Earth
AC or DC
Conforms to EU directives
Overvoltage (Installation) Category III. Pollution Degree 2 per
ICE 1010-1 refers to the level of Impulse withstand voltage
protection provided. Equipment of Overvoltage Category III is
equipment in fixed installations (e.g.,electricity meter and
primary over-current protection equipment).
3. SAFETY INFORMATION
CAUTION identifies conditions and actions that may damage the
phase rotation indicator.
WARNING identifies conditions and actions that pose a hazard to
the user. To avoid possible electric shock or fire, do the following:
• Read the following safety information carefully before using or servicing
the instrument.
• Adhere to local and national safety codes.
• Individual protective equipment must be used to prevent shock and
injury.
• Use of instrument in a manner not specified by the manufacturer may
impair safety features/protection provided by the equipment.
• Avoid working alone.
• Inspect the test leads for damaged insulation or exposed metal. Check
test lead continuity, damaged leads must be replaced, do not use the
phase Rotation indicator if it looks damaged.
• Be careful when working above 30V AC RMS, 42V AC peak and 60V DC,
Such voltages pose a shock hazard.
• When using the probes, keep fingers away from probe contacts, keep
fingers behind the finger guards on the probes.
