Table 3 - Protection device and wire ratings
Note: All wire sizes are based on 75 °C (167 °F) copper wire. Higher temperature smaller
gauge wire may be used per National Electric Code (NEC) and local codes.
Recommended fuses are based on 25 °C (77 °F) ambient, maximum continuous
control output current and no harmonic current. Earth/ground wires must be the
same gauge, or larger, than the Line wires.
3.4.6 Drive overload protection
The MicroFlex e100 will immediately trip and disable if there is an overload condition. The
parameters for managing drive overloads are configured automatically by the Commissioning
Wizard (see section 6.4.3). If they need to be changed, use the Parameters tool in Mint
WorkBench (see section 6.5.2).
