Terminal Identification
The connectors for input and output power, auxiliary relay connections,
and external DC bus are identified in the tables below.
CAUTION
Drive Failure!
Do not connect input power to drive output
motor terminals. Connecting input power to
motor terminals will result in drive failure when
power is applied.
On drives with an auxiliary enclosure, some or all of the power
connections at the drive will be factory made. Custom input and output
terminals may be inside the auxiliary enclosure. See the drawings
supplied with the drive for details on custom terminal blocks and conduit
entry locations for the auxiliary enclosure.
Input Power Delay
To ensure that the input surge suppression circuitry performs correctly,
a time delay between successive applications of input power must be
observed.
The table below shows the minimum time that must be allowed between
applications of input power.
