Front Interface

• Start/Stop switch*: Start closes the DC contactor and allows user to connect the DC grid to the converter. Stop opens the contactor and disconnects DC grid*.
• DC Voltage Output LED: when this light is on, it indicates that a DC voltage is present/active on the converter side of the DC contactor.
• Start/Stop switch*: pressing start closes the AC contactor and allows user to connect the AC grid to the converter. Pressing stop opens the contactor and disconnects AC grid.
• L1 L2 L3 LEDs: when this light is on, it indicates that a voltage is present/active on the converter side of the AC controller.
• Emergency Stop*: shuts all contactors and cuts both AC and DC lines to the MMC.

* These switches are only operational when permission is given by the model running in the OP4510.

If no permission is given, the switches perform no action.

OP1260 Standard Configuration

• Power Switch. Power input from rack power bar that will provide auxiliary power to OP1260.
• DC FUSES: overcurrent protection shuts down DC current in the event of an overage.
• DC DISCONNECTOR: provides safety voltage shutdown/isolation on DC lines, with a safety lockout feature for padlocking the disconnector during service.
• P3 INPUT, P4 OUTPUT: P3 connects to the AC and DC power input cables and P4 connects the protection box’s outputs to the OP1261 Measurement Box
• AC DISCONNECTOR: provides safety voltage shutdown/isolation on AC lines, with a safety lockout feature for padlocking the disconnector during service.
• AC LINES BREAKER: overcurrent protection shuts down AC current in the event of an overage. EARTH: (ground) connector
