1. Introduction
Please take a few minutes to read through this part of the introductory chapter carefully before plugging the line connector into the wall outlet.
This instrument has been designed and tested for Measurement Category I, Pollution Degree 2, in accordance with EN 61010-1:2011, and CSA C22.2 No 61010-1-12 (including approval). It has been supplied in a safe condition. Study this manual thoroughly to acquire adequate knowledge of the instrument, especially the section on Safety Precautions hereafter and the section on Installation.
2. Safety Precautions
All equipment that can be connected to line power is a potential danger to life. Handling restrictions imposed on such equipment should be observed.
To ensure the correct and safe operation of the instrument, it is essential that you follow generally accepted safety procedures in addition to the safety precautions specified in this manual.
The instrument is designed to be used by trained personnel only. Removing the cover for repair, maintenance, and adjustment of the instrument must be done by qualified personnel who are aware of the hazards involved.
The warranty commitments are rendered void if unauthorized access to the interior of the instrument has taken place during the given warranty period.
3. Caution and Warning Statements
CAUTION: Shows where incorrect procedures can cause damage to, or destruction of equipment or other property.
WARNING: Shows a potential danger that requires correct procedures or practices to prevent personal injury.
4. Symbols
Shows where the protective ground terminal is connected inside the instrument. Never remove or loosen this screw.
This symbol is used for identifying the functional ground of an I/O signal. It is always connected to the instrument chassis.
Indicates that the operator should consult the manual.
Personal safety is ensured when the input signal level is below 30 Vrms (when accidently touching the input signal lead), there are no transient voltages intended on the measuring terminals.
Damage level for the input decreases from 350 Vp to 12Vrms when you switch the input impedance from 1 MΩ to 50 Ω.
Measurement BNC cables length shall be kept below 3m.
Circuits of external devices connected to BNC sockets, USB sockets and Ethernet sockets should be separated from the power supply network (and from other sources of dangerous voltage) at the level of reinforced insulation.This separation should not be confused with the permissible voltage of the external signal, including the voltage of 350 Vp referred to in the manual. If the equipment is used in a manner not specified by the manufacturer, the protection provided by the equipment may be impaired.
5. If in Doubt about Safety
Whenever you suspect that it is unsafe to use the instrument, you must make it inoperative by doing the following:
- Disconnect the line cord
- Clearly mark the instrument to prevent its further operation
- Inform your Pendulum Instruments representative.
For example, the instrument is likely to be unsafe if it is visibly damaged.
6. Disposal of Hazardous Materials
There are no batteries or other potentially hazardous materials included.
You should dispose of your worn-out Frequency Analyzer, after a long and happily life, at an authorized recycling station or return it to Pendulum Instruments.
