Section 1 Quick Start GuideQuick Start Guide 1-1MN715 OverviewIf you are an experienced user of baldor controls, you are probably already familiar withthe keypad programming and keypad operation methods . If so, this quick start guide hasbeen prepared for you. This procedure will help get your system up and running in thekeypad mode quickly and will allow motor and control operation to be verified. Thisprocedure assumes that the Control, Motor and Dynamic Brake hardware are correctlyinstalled (see Section 3 for procedures) and that you have an understanding of thekeypad programming & operation procedures.

9 It is not necessary to wire the terminalstrip to operate in the Keypad mode (Section 3 describes terminal strip wiringprocedures). The quick start procedure is as the Safety Notice and Precautions in section 2 of this the control. Refer to Section 3, Physical Location AC power. Refer to Section 3 AC Line Connections . the motor. Refer to Section 3, Motor Connections . Dynamic brake hardware, if required. Refer to Section 3, Optional Dynamic Brake Hardware . in the keypad. Refer to Section 3, Keypad Installation Start ChecklistCheck of electrical AC line voltage at source matches control all power connections for accuracy, workmanship and tightness as wellas compliance to control and motor are grounded to each other and the control isconnected to earth all signal wiring for certain all brake coils, contactors and relay coils have noise should be an R-C filter for AC coils and reverse polarity diodes for DCcoils.
