death.
Indicates a procedure, condition, or statement that, if not strictly observed, could result in damage to or de-
struction of equipment.

Note!
Indicates an essential or important procedure, condition, or statement.
1 - Safety Precautions
According to the EEC standards the AGL50-EV and accessories must be used only after checking that the
machine has been produced using those safety devices required by the 89/392/EEC set of rules, as far as the
machine industry is concerned. These standards do not apply in the Americas, but may need to be conside-
red in equipment being shipped to Europe.
Drive systems cause mechanical motion. It is the responsibility of the user to insure that any such motion
does not result in an unsafe condition. Factory provided interlocks and operating limits should not be bypas-
sed or modied.
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 amplier 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
anufacturer’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 ammable
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.
Strain Hazard:
Improper lifting practices can cause serious or fatal injury. Lift only with adequate equipment and trained
personnel.
Drives and motors must be ground connected according to the NEC.
Replace all covers before applying power to the Drive. Failure to do so may result in death or serious injury.
Adjustable frequency drives are electrical apparatus for use in industrial installations. Parts of the Drives are
energized during operation. The electrical installation and the opening of the device should therefore only be
carried out by qualied personnel. Improper installation of motors or Drives may therefore cause the failure of
the device as well as serious injury to persons or material damage. Drive is not equipped with motor over-
speed protection logic other than that controlled by software. Follow the instructions given in this manual and
observe the local and national safety regulations applicable.
Always connect the Drive to the protective ground (PE) via the marked connection terminals (PE2) and the
housing (PE1). AGL50-EV Drives and AC Input lters have ground discharge currents greater than 3.5 mA.
EN 50178 species that with discharge currents greater than 3.5 mA the protective conductor ground connec-
tion (PE1) must be xed type and doubled for redundancy.
The drive may cause accidental motion in the event of a failure, even if it is disabled, unless it has been
disconnected from the AC input feeder.
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 section 1.1.
