BONITRON M3460R-4CAB1-1XXA2 (A4) RIDE-THRU OPERATION MANUAL 1. Overview This document describes a rack mounted Ride-Thru module used to provide the DC bus power for multiple AC PWM inverter drives during a power line dip or phase loss situation. The Ride-Thru module is factory set to become active (begin supplying power) if the DC bus voltage drops to a preset level. - Page 4 MODEL SPECIFICATIONS PARAMETER M3460R-4CAB1-100A2 (A4) M3460R-4CAB1-150A2 (A4) Ride-Thru Module Number M3460R-4R1-100C2 M3460R-4R1-150C2 Maximum Rated Power 100 kW 150 kW Required Input Power 100kW w/2 sec. 2X surge capability 150kW w/2 sec. 2X surge capability Rated DC bus current 160 Amps...

3. Description of Operation 3.1 Ride-Thru Module The M3460R Ride-Thru module consists of three basic sections as described below. These basic sections are the Rectifier section, Boost Converter section, and Control Power Supply section. 3.1.1 Rectifier Section This section converts the 3-phase AC line to a nominal DC bus. The Rectifier section contains the fusing, diode bridge, DC bus filter capacitors and precharge circuitry for each stage of the module. - Page 6 3.2 Rack Display Panel The Rack Display Panel provides visual indication of the Ride-Thru module’s operating status and also permits a system test to be performed. For panel details, refer to Display Panel Layout drawing #970066P for option A2 panels or drawing #980265P for option A4 panels. 3.2.1 Bus Voltage Meter The Bus Voltage meter indicates the Ride-Thru DC bus voltage.
- Page 7 Please refer to the appropriate Customer Connections & Component ID drawing and doc.# 993004 Recommended Input Power Wiring Sizes And Power Source Fusing For Model M3460R Cabinet Mounted Ride-Thru Systems for additional information pertaining to this section.

3.4.2 Precharge Complete Output The Precharge Complete output is an isolated, open collector transistor output, which will be ON when the DC bus has reached a level of 560VDC, and the Run command is closed. The connections are located on terminals 7 (-) and 8 (+) of 4460C1 connector TS2. -

Bonitron Model M3460R Ride-Thru Inductive Boost Circuit - Theory of Operation CIRCUIT DESCRIPTION: Using the basic inductive boost circuit shown in Figure 1 as the main power source for an inverter, the voltage across capacitor C2 is equal to the nominal DC bus appropriate for the 3∅... - Page 10 The only field adjustment that is required for this circuit is the voltage at which the circuit threshold is needed. The M3460R Ride-Thru will continue to provide power to the load even for input voltage dips in excess of 50%, but at a reduced kW rating.

- Page 14 Refer to Typical Open Chassis Field Connections Layout drawing# 000205. Please note that the input power source and power wiring supplied to the M3460R Ride- Thru system must be capable of providing a 2-second surge at twice the rated power of the Ride-Thru system.
- Page 15 Most inverters have an under voltage trip point of -15% of nominal. Some inverters can be reprogrammed to change this trip level. Bonitron typically would like the DC bus threshold to be about -10% of the nominal bus. For example, Bonitron sets all 460VAC systems to hold the DC bus to 590Vdc •...
- Page 16 • Repeat step 4 8. Verify threshold setpoint. • Turn off the Bonitron Ride-Thru disconnect, and watch the DC bus voltage fall. (See threshold adjustment procedure) • AC VOLTAGE DIP LED comes ON immediately • RIDE-THRU ACTIVE LED will come ON when the bus drops to the threshold.
- Page 17 Ride-Thru module becomes active to regulate the DC bus voltage to the "Threshold" setpoint voltage. The "Threshold" level is factory preset on all Bonitron Model M3460 Ride-Thru modules. These levels are specified in the General Specifications section of the Customer Reference manual for each Ride-Thru module.
- Page 18 On modules so equipped, the "Test" button is located on the module's control/display front panel. For modules without a control/display front panel, a normally-open momentary switch should be installed to serve as a test switch for this procedure. Refer to applicable field wiring diagrams for switch connection points.
