Other Important Precautions
Pay attention to the following items. Failure to do so
can result in damage of inverter and/or electrical
shock.
▶
Handling and installation
1. Handle according to the weight of product.
Failure to do so can result in damage to product.
2. Do not stack inverters beyond listed
specifications.
3. Install according to specifications listed within
this manual.
4. Do not apply power to a damaged inverter or to
an inverter with missing components.
5. Do not open front cover while carrying inverter.
6. Do not place heavy items on inverter.
7. Installation orientation must follow specifications
listed within this manual.
8. Do not allow conducted material such as screws,
metal objects, water, or oil to enter interior of
inverter.
9. Do not drop or inflict intense impact to inverter.
10. Install and operate inverter only under specified
conditions.
▶
Wiring
1. Do not connect Power Factor capacitors, surge
suppressors, or RFI filters to output circuits.
2. Connect the output terminals (U, V, W) according
to specifications.
▶
Operation
1. CAUTION: When the retry function is selected
the inverter restarts after an alarm stop.
2. Stop key on keypad can only be used when stop
key function is set. Install separate emergency
stop switch if required.
3. When run signal is received, inverter restarts
only when alarm contents have been reset.
Verify run signal before resetting alarm.
4. Do not start or stop inverter using
electromagnetic switch installed in power input
circuit.
5. Do not modify or alter anything inside inverter.
