6.2 Power Connections
Refer to Figure 6-2 and Figure 6-3.
Figure 6-2 Single quadrant power connections
Access to the power terminals of the smaller Drives is gained by opening
the front cover, which is secured by two captive screws, one at each
upper corner, and hinged at the bottom (Figure 6-1). The higher-rated
models have externally-accessible terminal lugs.
6.2.1 Motor Rotation
Check that the direction of rotation is as required as soon as the Drive is
first turned on. If not, exchange the connections to the armature or the
field (but not both). If an encoder or tachogenerator (tachometer)
feedback is installed, the sense of the signals to the Drive must be
reversed to correspond.
The Drive control options can alternatively be used to reverse the
direction of rotation.
