Wiring
Warning
Mandatory
Electrical construction work must be done by a qualified expert.
Connection of input power by someone who does not have expert knowledge may result
in electric shocks or fire.
Turn off input power before wiring.
Wait at least 10 minutes and make sure that the charge lamp (on the inverter unit) is no
longer lit. Otherwise, it may lead to electric shocks.
Tighten the screws on the terminal blocks to the specified torque when connecting cables
to terminal blocks.
Otherwise, it may lead to fire.
Operations
Danger
Prohibited
Do not pull on the cable and connector.
It may cause damage or malfunctions.
Mandatory
Use this option under the environment specified in the instruction manual.
Usage under the environment other than them may cause damages or malfunctions or
an accident.
Use an additional safety device with your inverter or system to prevent a serious accident
due to the unit malfunctions.
Usage without an additional safety device may cause an accident.
Warning
Mandatory
Set up “Communication error trip function (see below)” to stop the inverter when the
option unit is deactivated by an unusual event such as an operating error, power outage,
failure, etc.
- Communication error trip time
(f803, see the inverter instruction manual for details)
- Receive heart beat timer
(See the VF-FS1
LONWORKS Communication Function Manual for details)
Deactivated option unit may cause an accident, if the “Communication error trip function”
is not properly set up.
Make sure that the operation signals are STOP before clearing the inverter’s fault. The
motor may suddenly start and that may result in injuries.
Disposal
Warning
Mandatory
If you dispose off this unit, have it done by a specialist in industrial waste disposal*.
Improper disposal may result in explosion of capacitors or produce noxious gases,
resulting in injuries.
(*) Persons who specialize in the processing of waste and known as “Industrial Waste
Product Collectors and Transporters” or “Industrial Waste Disposal Persons.” If the
collection, transport and disposal of industrial waste is done by someone who is not
licensed for that job, it is a punishable violation of the law (Laws in regard to cleaning and
processing of waste materials).
Notes on operation
Notes
Avoid installing in a place where ambient temperature or/and humidity change sharply.
Keep the transmission cable separate from the power cable of the inverter to prevent the
inverter from malfunctioning due to electromagnetic noise.
Ground of SHLD terminal on this option at the grounding terminal separated from those of
inverters and motors. It may cause malfunction due to noise.
