Installation
4.3.1 Drive Cabinet Main Power Connection
Always follow applicable local electrical safety codes when installing wire
and cables.
1. If conduit is not installed, use chase nipples with bushings or other suitable
means to protect the wire and cables.
2. Check the main breaker size in the drive cabinet to determine required power
conductor size for this installation.
3. If the wire from the distribution panel to the drive cabinet is long, increase wire
size to keep the voltage drop to less than 5 percent of nominal.
The prime power required for the standard drive system
is 3 phase WYE, 5-
wire with ground. Other prime power
configurations are available by special order. The neutral wire of
the power system must be installed for proper operation.
4. Connect the three-phase line leads to the line side (top) of the main circuit
breaker in the upper right corner of the drive cabinet. Refer to Figure 4-3 for a
drawing of the drive cabinet.
