RIVE PTIONS In 1975, Bonitron began working with AC inverter drive specialists at synthetic fiber plants to develop speed control systems that could be interfaced with their plant process computers. Ever since, Bonitron has developed AC drive options that solve application issues associated with modern AC variable frequency drives and aid in reducing drive faults.

URPOSE AND COPE This manual is a user’s guide for the Model M3460D Diode Sharing Module. It will provide the user with the necessary information to successfully install, integrate, and use the M3460D module in a variable frequency AC drive system.
M3460D 1.1. YMBOL ONVENTIONS SED IN THIS ANUAL AND ON QUIPMENT Earth Ground or Protective Earth AC Voltage DC Voltage DANGER: Electrical hazard - Identifies a statement that indicates a shock or electrocution hazard that must be avoided. DANGER! DANGER: Identifies information about practices or circumstances that can lead to personal injury or death, property damage, or economic loss.
ESCRIPTION EATURES Bonitron’s M3460D Diode Sharing Modules are designed to offer system integrators a low cost solution for using a DC Bus Ride-Thru Module (RTM) with multiple fixed bus Variable Frequency Drives. The modules provide isolation for positive current flow to the drive.

User’s Manual NSTALLATION NSTRUCTIONS 3.1. RODUCT NSPECTION Upon receipt of this product, please verify that the product received matches the product that was ordered and that there is no obvious physical damage to the unit. If the wrong product was received or the product is damaged in any way, please contact the supplier from which the product was purchased.
M3460D 3.4.1.1. ONNECTION The DC bus input should be connected to the output of the Ride-Thru module. Make sure that the DC bus connection polarity is correct. Improper polarity connections carry a high risk of damaging drive equipment if energized.
User’s Manual PERATION 4.1. UNCTIONAL ESCRIPTION The Diode Sharing Module isolates the DC bus connections of multiple drives to keep from generating circulation currents in the AC bridges of the drives. This ensures that the input bridges of each drive do not supply power to other drives in the network, or allow circulating currents between drives.
