The following instructions are provided for your safety and as a means of preventing damage to the product or
components in the machines connected. This section lists instructions, which apply generally when handling electrical
drives.
Specific instructions that apply to particular actions are listed at the beginning of each chapters.
Read the information carefully, since it is provided for your personal safety and will also help prolong the service life of

2.3 General warnings
This equipment contains dangerous voltages and controls potentially dangerous rotating
mechanical parts. Non-compliance with Warnings or failure to follow the instructions contained in
this manual can result in loss of life, severe personal injury or serious damage to property.
Only suitable qualified personnel should work on this equipment, and only after becoming familiar
with all safety notices, installation, operation and maintenance procedures contained in this manual.
The successful and safe operation of this equipment is dependent upon its proper handling,
installation, operation and maintenance.
In the case of faults, the drive, even if disabled, may cause accidental movements if it has not been
disconnected from the mains supply.
Electrical Shock
The DC link capacitors remain charged at a hazardous voltage even after cutting off the power
supply.
Never open the device or covers while the AC Input power supply is switched on. Minimum time to
wait before working on the terminals or inside the device is listed in next page (see “Minimum time
required for safe DC-link voltage”).
Electrical Shock and Burn Hazard:
When using instruments such as oscilloscopes to work on live equipment, the oscilloscope’s
chassis should be grounded and a differential probe input should be used. Care should be used in
the selection of probes and leads and in the adjustment of the oscilloscope so that accurate
readings may be made. See instrument manufacturer’s instruction book for proper operation and
adjustments to the instrument.
Fire and Explosion Hazard:
Fires or explosions might result from mounting Drives in hazardous areas such as locations where
flammable or combustible vapors or dusts are present. Drives should be installed away from
hazardous areas, even if used with motors suitable for use in these locations.
