1-14NOTES FOR FIGURE 1-5✱ – Indicates components not supplied.– Main circuit terminal.– Indicates control circuit terminal.( ) – Indicates alternate terminal marking, i.e., (R) and L1.▲ – Function labels shown for these terminals are determined by factory settings of n050through n056 (see paragraph 5.18).● – Function labels shown for these terminals are determined by factory settings of n057 through n059(see paragraph 5.19).♦ – Function label shown for this terminal is determined by factory setting of n004 (see paragraph 5.11A).■ – Function labels shown for these terminals are determined by factory setting of n066 (see paragraph 5.17).1. Insulated twisted shielded wire is required.2-conductor #18 GA. (Belden #8760 or equivalent).3-conductor #18 GA. (Belden #8770 of equivalent).Connect shield ONLY AT the Drive END (ground terminal ). Stub and isolate other end.2. +12V voltage output current capacity of control terminal FS is 20mA max.3. The Drive’s Electronic Thermal Overload function (n036, n037) meets standards set by UL and CUL for motor ther-mal overload protection. If local code requires a separate mechanical overload protection, an overload relay shouldbe installed, interlocked with the Drive as shown. It should be the manual reset type to prevent automatic restart fol-lowing a motor fault and subsequent contact reclosure after cool down.4. Customer to connect terminal to earth ground.5. If the Digital Operator is used, remote operators, which duplicate functions of its command keys may not berequired. See Figure 4-1.6. For installation of Braking Resistor or Braking Resistor unit, refer to Appendix 6, “Dynamic Braking Option.”7. An optional DC reactor may be added for harmonic attenuation, if needed. See separate instruction sheet for wiring.8. If application does not allow reverse operation, parameter n006 , Reverse Run Prohibit Selection, should be set to“ 1 ” (Reverse Run Disabled), and the Reverse Run/Stop input can be eliminated.9. Input fuses are required for proper branch circuit short circuit protection for all NEMA Type 4 drives. Failureto use recommended fuses (see appendix 4) may result in damage to the drive and/or personal injury.F. Interconnection - 2 WireContinued1.4 ELECTRICAL INSTALLATIONWARNING
