Wiring
1. Prior to wiring, refer to the name plate mounted to the motor portion of the Hyponic® unit. Check the power
supply, interconnects, relays, protective starting devices (i.e, Star (Wye) delta - if reduced voltage starting is
required), space heaters, thermal sensors and other accessories.
2. Be aware that long wiring may cause voltage drops.

Tighten both pairs of nuts against the mounting tab so that there is zero clearance between the rubber
bushings and the tab, but you can still rotate the rubber bushings by hand. Do not overtighten, but ensure
that the nuts in each pair are tightened securely against each other so vibration will not cause them to
loosen. Be sure that the bottom of the mounting angle bracket is secured to a rigid surface.
The Hyponic® T-type torque arm design allows for reversing rotation and can be mounted to accept loads in tension
or compression. Any of the mounting positions shown in Figure 12 are permissible. Table 5 shown below, mentions
the necessary components for a proper operation of the T-type torque arm.
During the operation, the Hyponic® unit will rotate in the direction opposite to that of the driven shaft.
