Page 35 WARNING DANGEROUS VOLTAGES, capable of causing death or serious injury, are present on the external terminals and inside the equipment. Use extreme caution and follow all safety rules when handling, testing or adjusting the equipment. However, these internal voltage levels are no greater than the voltages applied to the external terminals.
Page 36 PRODUCT CAUTIONS Before attempting any test, calibration, or maintenance procedure, personnel must be completely familiar with the particular circuitry of this unit, and have an adequate understanding of field effect devices. If a component is found to be defective, always follow replacement procedures carefully to that assure safety features are maintained.

Appendix – B Communications The M-3311A Transformer Protection Relay incorporates three serial ports for intelligent, digital communication with external devices. Equipment such as RTUs, data concentrators, modem, or computers can be interfaced for direct, on-line real time data acquisition and control. Generally, all data available to the operator through the front panel of the relay with the HMI is also accessible remotely through the BECO 2200 data exchange protocol.
Page 406: M-3311 Slave Address
M‑3311A Instruction Book M-3311 Slave Address DNP3 Slave IED address range is from 0 to 65519. Address 65535 (hex FFFF) is used to broadcast messages to all devices. The communication address can be set through the HMI (front panel; optional). The DNP3 device profile document, including the point list, is available from the factory or our website, www.beckwithelectric.com.
