Installation Confirmation; Basic Commissioning - TECHTOP TD350 Product Manual

TD350 Series VFD
2. Check whether ambient temperature of the VFD during actual application is below -10° C, if
yes, install heating facility.
Note: For cabinet-type VFD, 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 VFD is installed properly, check the installation condition of the VFD.
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 VFD are of
correct type and installed properly; check whether the installation cables fulfill requirements
on current-carrying capacity.
3. Check whether the VFD 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 VFD
requirements.
6. Check whether installation spacing of the VFD complies with the requirements in operation
manual.
7. Check whether installation mode of the VFD complies with the requirements in operation
manual. Vertical installation should be adopted whenever possible.
8. Check whether external connecting terminals of the VFD 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
VFD, if yes, take them out.

2.6 Basic commissioning

Carry out basic commissioning according to the following procedures before operating on the VFD.
1. Select motor type, set motor parameters and select VFD control mode according to actual
motor parameters.
