S1 series standard inverter
-3-
Installation site should be away from children and other public places;
The inverter cannot meet the requirements of low voltage protection in IEC61800-5-1 if the
altitude of installation site is above 2000m;
The inverter should be used in proper environment (see chapter 4.2.1 Installation environment
for details);
Prevent the screws, cables and other conductive parts from falling into the inverter;
As leakage current of the inverter during running may exceed 3.5mA, ground properly and
ensure the grounding resistance
is less than 10Ω. The conductivity of PE grounding conductor is
the same with that of the phase conductor (with the same cross sectional area).
L, N (230V) or R, S and T (400V) are the power input terminals, and U, V and W are output motor
terminals. Connect the input power cables and motor cables properly; otherwise, damage to the
inverter may occur.
1.4.2 Commissioning and running
Disconnect all power sources applied to the inverter before terminal wiring, and
wait for at least the time designated on the inverter after disconnecting the
power sources.
High voltage presents inside the inverter during running. Do not carry out any
operation on the inverter during running except for keypad setup. For products
at voltage levels of 5 or 6, the control terminals form extra-low voltage circuits.
Therefore, you need to prevent the control terminals from connecting to
accessible terminals
of other devices.
The inverter may start up by itself when P01.21 (restart after power down) is set
to 1. Do not get close to the inverter and motor.
The inverter cannot be used as "Emergency-stop device".
The inverter cannot act as an emergency brake for the motor; it is a must to
install mechanical brake device.
Note:
Do not switch on or switch off input power sources of the inverter frequently;
For inverters which have been stored for a long time, set the capacitance and carry out
inspection and pilot run on the inverter before use.
Close the front cover before running; otherwise, electric shock may occur.
1.4.3 Maintenance and component replacement
Only well-trained and qualified professionals are allowed to perform
maintenance, inspection, and component replacement on the inverter.
Disconnect all the power sources applied to the inverter before terminal
wiring, and wait for at least the time designated on the inverter after
disconnecting the power sources.
Take measures to prevent screws, cables and other conductive matters from
falling into the inverter during maintenance and component replacement.
