3. Compliance with Connection
The opening of the branch circuit protective device may be an
indication that a fault current has been interrupted. To reduce the risk
of fire or electrical shock, current-carrying parts and other components
of the controller should be examined and replaced if damaged.
If burnout of the current element of an overload relay occurs, the
complete overload relay must be replaced.

For recommended tightening torque, see Table 1.
Use the ring terminal for the earth cables, see Table 2.
For recommended electric wire sizes, see Table 3,4.
Use the electric wire of Class1 for the control circuits.
For instruction in the United States, Integral solid state short circuit protection does not provide branch circuit protection.
Branch circuit protection must be provided in accordance with the National Electrical Code and any additional local codes.
For instruction in the Canada, Integral solid state short circuit protection does not provide branch circuit protection. Branch
circuit protection must be provided in accordance with the Canadian Electrical Code, Part I. .
