Page 20: Physical Construction & Mounting
2.0 PHYSICAL CONSTRUCTION & MOUNTING The M350 meters are packaged in rugged aluminum case specifically designed to meet the harsh conditions found in utility and industrial applications. The Front panel view of the V3 3-phase voltmeter is shown in Figure 1. The A3 3- phase ammeter is not shown, but would look similar indicating Amps for engineering units.

Page 22: Initial Inspection
Bitronics instruments are carefully checked and "burned in" at the factory before shipment. Damage can occur however, so please check the instrument for shipping damage as it is unpacked. Notify Bitronics LLC immediately if any damage has occurred, and save any damaged shipping containers.
Page 23: Cleaning
Cleaning the exterior of the instrument shall be limited to the wiping of the instrument using a soft damp cloth applicator with cleaning agents that are not alcohol based, and are non-flammable and non-explosive. - 23 - ML0038 September 27, 2017 Copyright 2017 Bitronics, LLC...
Page 24: Back Panel & Wiring
3.0 BACK PANEL & WIRING The rear view of the M350 is shown in figure 3 with the option port shown (removable terminal block at the top), which may be selected at order time, as either, the serial communication option, the 0-1mA analog transducer output option, or the 4-20mA analog transducer output option.
Page 25: Auxiliary Power
Operating Range: 36-300V dc, 55-275V ac (45-65Hz) 3.2 M350 V3 VT Inputs – VA, VB, VC, VN (See Appendix A1 and Section 1.3) The M350 V3 meter voltage (VT) signal inputs are connected to terminals 3-6 (see Appendix A1 for specific wiring configurations). Voltage signals are measured using a 12M ohm resistor divider with a continuous voltage rating of 7kV.
Page 26: Serial Ports (See Section 4.2)
Transformers (CTs). 3.4 Serial Ports (See section 4.2) The M350 meters are equipped with an optional serial port. The port is software (user) configurable for RS-232 or RS-485. The RS-232 drivers support full and half duplex modes. See Figures 7-8 for signal assignments.
Page 27 Enter Network addresses using the meter’s front buttons: Refer to the section in this manual on “Navigating the M350’s setup menu from the Front panel” for further instruction regarding the button sequence you will use to scroll through the menu structure.
Page 28 Although the IP address can be obtained via the display, for versions that don’t have a display (M651, M661, PPX II), Bitronics has created a utility program to request the IP address for a specific MAC address on an Ethernet network. This program can be used with the M650 as well.
Page 29: Indicators - Ethernet (Act) & Serial Leds
The ability to upgrade Firmware is done over the Ethernet port. The M350 family utilizes a page in the Web Server interface to upload and install new firmware. A password protected hyperlink is provided from the Configuration Settings Page that navigates to the Firmware Upload page.
Page 30 Figure 4 – Bitronics M350 Firmware Upload Page Once the Firmware Upload page is visible, use the Browse button to locate the firmware image on your computer. Next use the Submit button to initiate the file transfer and installation process. The instrument must be rebooted to make the new firmware active.

M350 V3 must create it from the vector sum of the other two phase-to-neutral voltages. In order to configure the M350 V3 for 2½ element mode and which phase voltage is missing, select one of the following: 2.5 element - A, 2.5 element - B, or 2.5 element –...
Page 62: Ampere Demand (M350 A3)
6.4.4 Demand Interval The M350 uses 900 seconds (15 minutes) as the default demand interval for current in the A3. The default for average volts and average power measurements is 60 seconds in the V3.
Page 63: Heartbeat And Health Check
The table below provides a reference of error codes. The Health Check value shown in the M350 web live data page is a hexadecimal representation of the binary value. For example, a Health Check value of 0000 0014 is the equivalent of the binary value 000000000010100.
Page 64: Calibration
6.8 Instantaneous Measurement Principles The M350 measures all signals at an effective rate of 64 samples/cycle, accommodating fundamental signal frequencies from 45 to 65Hz depending on model. Samples of all bus signals are taken using a 16-Bit A/D converter, effectively creating 64 "snapshots"...

Some hubs/switches will not output an optical idle unless they receive an optical idle. This then inhibits the converter from outputting a copper link pulse enabling the M350 to link. In this condition, no device completes the link.
