1.3.9 Make Precautionary Checks Before Operation
1. Make sure the input voltage level to the drive is correct. Refer to the Drive Specification
Tables 1.1.1 and 1.1.2.
2. Check the power and control connections. All wires should be connected tightly to the
terminal.
3. Check the 120VAC source for the control pushbutton.
4. The length of the output wires between the SV200 and the motor must not exceed 100
feet.
5. Check the drive and motor ground and make sure there is no ground loop problem.
Ensure that all motors and drives connected from a common panel are connected to a
single ground point. See Fig. 1.3.7 for an example.
