Page 21: Operation
UTAGE ROTECTION The M3460UC can be used with an energy storage system to allow for protection against sags and full outages for up to 2 seconds. This storage is typically double layer capacitors or ultracapacitors, but can be any DC power source that needs regulation to attach to the DC input of a variable frequency drive. - Page 22 M3460 4.4. ISPLAY NTERFACE The 3660DD5 is composed of two circuit boards, the 3660I4 interface board and the 3660D5 display board. The display board provides the user interface and keeps time. The interface board accepts digital and analog signals from the ride-thru system and the user, and processes them before sending them to the display board via CANbus.

Page 30: Dc Bus Threshold Voltage Setting
M3460 4.8. DC B HRESHOLD OLTAGE ETTING The DC bus threshold voltage is the voltage at which the M3460 maintains the DC bus during a power quality event. Whenever the output DC bus voltage drops below the DC bus threshold voltage setting, the M3460 becomes active to regulate the DC bus to the setpoint voltage. -

Page 33: Start-Up, Maintenance And Troubleshooting
AINTENANCE TEMS The M3460 is designed to require very little maintenance. Bonitron recommends a yearly test of the system in order to ensure the system is functioning properly. If the system is equipped with displays, then the cycle counters should indicate the number of events since the last reset. - Page 34 100% rated voltage, and caps run full ripple current at 1% duty. With typical operating conditions of 35°C, caps running at 75% rated voltage, and a duty cycle of one event per month, Bonitron recommends the capacitors be checked or replaced after 20 years.

M3460R M ROTECTION ODELS Bonitron M3460R models can have energy storage devices added to cover complete outages. This involves adding a capacitor bank with an appropriate charging and discharging system. Bonitron can source complete capacitor cabinets or individual capacitors. This section gives some instruction for sizing and specifying these storage devices. - Page 46 M3460 However, an additional power supply, the ASM 3460PS is required when the total voltage across the ultracapacitor bank is lower than the Precharge Complete Voltage (PCC). See Table 6-3 for the minimum PCC voltage required to bring the Ride-Thru into operation.
