Comparison Description	The button is small so it’s inconvenient to press, and the silicone button is easy to get stuck.	The operation button is upgraded and the surface of finger pressing is enlarged, which is easy to press. The structure of the silicone button is upgraded to solve the problem of easy getting stuck.

Physical Picture
Comparison Description	The upper and lower covers of the keyboard are matched with buckles. The gaps between the two covers are uneven. The buckles are not tight enough and easy to loosen. The buckles are exposed which affects the appearance.	The upper and lower covers of the keyboard are fixed by screws at the bottom, which is very firm. And the matching position is hidden at the bottom to ensure the surface could be more beautiful.

Physical Picture
Comparison Description	There is no guidance of the external keypad opening size at the bottom, and the opening size needs to check in the user manual, which is inefficient.	After the upgrade, it adds an opening size diagram at the bottom when the keyboard needs to be drawn out, which can be viewed immediately without having to read the manual.

5. Motor Wiring
◆ It is forbidden to short circuit or ground the inverter output terminal, otherwise the internal components of the inverter will be damaged.
◆ Avoid short circuit the output cables or with the inverter enclosure, otherwise there exists the danger of electric shock.
◆ It is forbidden to connect the output terminal of the inverter to the capacitor or LC/RC noise filter with phase lead, otherwise, the internal components of the inverter may be damaged.
◆ When contactor is installed between the inverter and the motor, it is forbidden to switch on/off the contactor during the running of the inverter, otherwise, there will be large current flowing into the inverter, triggering the inverter protection action.
◆ Length of cable between the inverter and motor If the cable between the inverter and the motor is too long, the higher harmonic leakage current of the output end will produce by adverse impact on the inverter and the peripheral devices. It is suggested that when the motor cable is longer than 100m, output AC reactor be installed. Refer to the following table for the carrier frequency setting
