Installation - Watt Drive L2000 Series Manual

Installation

The inverter must be mounted vertically on a non-flammable wall in order to prevent from
overheating and fire. The minimum clearances to the surrounding walls shown in the figure below
must be complied with to ensure a good ventilation. Foreign matter (especially conductive objects)
must nut be dropped into the inverter since they not only cause malfunction and damage but may
also lead to electrical and fire hazards.
Cover all ventilation holes on the inverter during installation so that no foreign objects can enter the
inverter. Be sure to remove those covers from the inverter before you put the inverter to work.
The minimum clearances to the surrounding walls shown in the figure are only meant for reference.
A more compact installation (back to back) may well be possible and should be discussed with
WATT DRIVE. Please always leave enough room for the key cover to be opened without problems
in order to connect wires to the control terminals.
The ambient temperature should be in the range of -10°C to 50°C. At a temperature of 40~50°C
the carrier frequency has to be reduced to 2kHz, the output current must be kept below 80% of the
rated current, and the top cover (see figure below) has to be removed. Higher ambient temperature
causes shorter inverter life. So if there is hot equipment in the vicinity of the inverter, keep it away
from the inverter as far as possible.
If the inverter is to be installed in a cabinet, ambient temperature is considered to be the
temperature prevailing withing this cabinet. Fans have to be provided if necessary so that ambient
temperature remains within the limits specified above.
For safety reasons the digital operator must be closed and not be opened during inverter operation.
The end application must be in accordance with the BS EN 60204-1 standard.
