The BIM is used to access, configure, test and display information for OPTIM trip units and other devices. The BIM consists of four display windows, eight function buttons, eighteen LED s and a graphical time/current curve to provide breaker status, operational information, protection status and energy monitoring. A 30 Vdc power supply is required to provide power to the BIM. This is supplied by the switchboard builder to Cutler-Hammer specifications. The BIM is a member of the IMPACC family of communicating devices that connects OPTIM trip units, Digitrip RMS 810/910 trip units and energy sentinels as a subnetwork system. The BIM can also be connected to a main network via a PONI module to IMPACC Series III software. For detailed information on the BIM refer to SA BIM The Digitrip OPTIMizer is a hand held programmer that is used to access, configure, test and display information from OPTIM trip units. The OPTIMizer plugs into the front of an OPTIM trip unit via an eight-pin telephone jack and is powered by a nine-volt battery. In addition, a 3-pin Incom network connection is also provided to program other OPTIM devices on the system. An Auxiliary Power Module connection is provided to provide control power to perform a trip test when control power is not present at the breaker. The OPTIMizer is supplied as a standard package to include the programmer, the eight-pin connection cord, battery and carrying case. The network connection cord and Auxiliary Power Module are optional. OPTIMIZER Standard Package ICC Incom Connection Cord The Auxiliary Power Module is a power supply requiring 10 Vac input at 50 or 60 Hz that provides a 3 Vdc output. The Auxiliary Power Module provides control power for testing an OPTIM trip unit when other means of control power is not available. The Auxiliary Power Module connects into the top of the Digitrip OPTIMizer via a keyed receptacle. The main application for the Auxiliary Power Module would be for the testing of a stand alone non-communicating OPTIM breaker that ordinarily would not have control power. PRTAAPM

10 9-10N Page 6. Series C External Accessories GROUND FAULT ALARM UNIT POTENTIAL TRANSFORMER MODULE IMPACC SOFTWARE The Ground Fault Alarm Unit is a remotely mounted device with a combination indicating light/test button that will light when the breaker trips or alarms on ground fault. The Ground Fault Alarm Unit requires a separate 10 Vac power source to power the light and the internal relay which has 1 N.O. and 1 N.C. contacts for remote indication. The Ground Fault Alarm Unit can be panel mounted for ordering with an optional face mounting bracket. GFAU Ground Fault Alarm Unit STYLE NUMBER Face Mounting Bracket 164C67G01 The Potential Transformer Module is required for Series C, Digitrip OPTIM 1050, to provide a voltage input to allow the trip unit to monitor power and energy as well as power factor. The Potential Transformer Module is a 6VA transformer with a primary voltage input of up to V line to line. Three 0.1 ampere fuses are provided on the primary of the transformer and can be used for isolation puposes during dielectric testing. The device is normally panel mounted and can feed up to 16 OPTIM trip units. DOPTMLN Series C Digitrip OPTIM trip units can communicate back to a central Personal Computer by installing Cutler-Hammer Series III software. In addition other software packages are available to allow the user to configure the trip units as well as perform online coordination. For more information on this please refer to IMPACC sales aid SA Vdc Power Supply te: A 30 Vdc power supply is required for all Digitrip OPTIM trip units that are required to communicate either on the main IMPACC network or as a subnetwork to a BIM. Typically one 30 Vdc power supply is required per switchboard and can provide control power to a BIM and up to 16 OPTIM trip units. The 30 Vdc power supply can be an off the shelf power supply and is normally provided by the switchboard manufacturer to Cutler-Hammer recommendations.
