General Information

3-4 Receiving & Installation MN715

Electrical Installation To make electrical connections, use UL listed closed loop connectors that are of

appropriate size for wire gauge being used. Connectors are to be installed using crimp

tool specified by the manufacturer of the connector. Only Class 1 wiring should be used.

Baldor Series H controls feature UL approved adjustable motor overload protection

suitable for motors rated at no less than 50% of the output rating of the control. Other

governing agencies such as NEC may require separate over-current protection. The

installer of this equipment is responsible for complying with the National Electric Code

and any applicable local codes which govern such practices as wiring protection,

grounding, disconnects and other current protection.

System Grounding Baldor Controls are designed to be powered from standard three phase lines that are

electrically symmetrical with respect to ground. System grounding is an important step in

the overall installation to prevent problems. The recommended grounding method is

shown in Figure 3-1.
