HD2 IP55 High-ingress Protection Series Inverters
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.
3.
Adjust the acceleration and deceleration time based on actual working conditions of the
load.
4.
Jogging to carry out device commissioning. Check whether the motor running direction
is consistent with the direction required, if no, it is recommended to change the motor running
direction by exchanging the motor wiring of any two phases.
5.
Set all the control parameters and carry out actual operation.
