Installation Confirmation; Basic Commissioning - Hitachi S1 Series Basic Manual

S1 series standard inverter
Note: For cabinet-type inverter, its ambient temperature is the air temperature inside the
cabinet.
3. Check whether the altitude of the application site exceeds 1000m, if yes, derate 1% for
every additional 100 m.
4. Check whether the humidity of application site exceeds 90%, if yes, check whether
condensation occurred, if condensation does exist, take additional protective measures.
5. Check whether there is direct sunlight or animal intrusion in the application site, if yes, take
additional protective measures.
6. Check whether there is dust, explosive or combustible gases in the application site, if yes,
take additional protective measures.

2.5 Installation confirmation

After the inverter is installed properly, check the installation condition of the inverter.
1. Check whether the input power cable and current-carrying capacity of the motor cable fulfill
actual load requirements.
2. Check whether peripheral accessories (including input reactors, input filters, output
reactors, output filters, DC reactors, brake units and brake resistors) of the inverter are of
correct type and installed properly; check whether the installation cables fulfill requirements
on current-carrying capacity.
3. Check whether the inverter is installed on fire-retardant materials; check whether the hot
parts (reactors, brake resistors, etc.) are kept away from combustible materials.
4. Check whether all the control cables are routed separately with power cables based on
EMC requirement.
5. Check whether all the grounding systems are grounded properly according to inverter
requirements.
6. Check whether installation spacing of the inverter complies with the requirements in
operation manual.
7. Check whether installation mode of the inverter complies with the requirements in operation
manual. Vertical installation should be adopted whenever possible.
8. Check whether external connecting terminals of the inverter are firm and tight enough, and
whether the moment is up to the requirement.
9. Check whether there are redundant screws, cables or other conductive objects inside the
inverter, if yes, take them out.

2.6 Basic commissioning

Carry out basic commissioning according to the following procedures before operating on the
inverter.
1. Select motor type, set motor parameters and select inverter control mode according to
actual motor parameters.
2. Whether autotuning is needed? If possible, disconnect the motor load to carry out dynamic
parameter autotuning; if the load cannot be disconnected, perform static autotuning.
