Please read this manual carefully before you install and operate an L2500 series inverter
and observe all of the instructions given in there. This manual may also serve as a
reference guide and therefore should always be kept at hand.
!
DANGER!
This message indicates a situation which may lead to serious injury or even
death if the instruction is not observed.
!
CAUTION!
This message indicates a situation which may lead to minor or moderate
injury, or damage of product.
!
HAZARDOUS HIGH VOLTAGE!
Motor control equipment or electronic controllers are connected to hazardous
line voltages.
When servicing drives and electronic controllers there might exist exposed
components with cases or protrusions at or above line potential.
Extreme care should be taken to protect against shock.
For these reasons, the following safety guidelines should be observed:
Stand on an insulating pad and make it a habit to use only one hand when
checking components. Disconnect power before checking controllers or
performing maintenance. Be sure that equipment is grounded properly. Wear
safety glasses whenever working on an electronic controller or rotating
electrical equipment.
!
DANGER!
This equipment should be installed, adjusted and serviced only by qualified electrical
maintenace personel familiar with the construction and operation of the equipment
and the hazards involved. Failure to observe this precaution could result in bodily
injury.
!
CAUTION!
These instructions should be read and clearly understood before working on L2500
series equipment.
!
DANGER!
The user is responsible that all driven machinery, drive train mechanism not
supplied by WATT Drive Antriebstechnik and process line material are capable of safe
operation at an applied frequency of 150% of the maximum selected frequency range to
the AC motor. Failure to do so can result in destruction of equipment and injury to
personnel should a single point failure occur.
!
DANGER!
HAZARD OF ELECTRICAL SHOCK. DISCONNECT INCOMING POWER BEFORE
WORKING ON THIS CONTROL.
Do not connect or disconnect wires and connectors while power is applied to the
circuit. Maintenance must be performed by qualified technicians.
!
DANGER!
A charge may still remain in the DC-link capacitor with hazardous voltages even if the
power has been turned off. To avoid personal injury, please ensure that power has
turned off before operating AC drive and wait ten minutes for capacitors to discharge
to safe voltage levels.
!
CAUTION!
Proper grounds, disconnecting devices (e.g. fuses) and other safety devices and
their location are the responsibility of the user and are not provided by WATT Drive.
