Each operator must read and understand this Instruction Manual prior to operating the equipment. The Safety precautions, herein, are not intended to replace your Company’s Safety Procedures. -
Page 9: Figure 1: Input Power Board
Installation Figure 1: Input Power Board When using AC, the neutral pole must be at ground potential. Before making connection to the power source, determine that the instrument rating matches the voltage of the power source. Do not bypass the grounding connection. The ground terminal of the input supply (green or yellow/green wire) must be connected to the protective ground (earth) terminal of the line power source. -
Page 10: Installation
To facilitate installation, a union along with a 1 ½” MNPT nipple is provided with each InsuLogix G2. Use of these fittings is recommended to eliminate the need to rotate the unit during mounting. Do NOT use galvanized fittings as the coating on them is known to react with the oil and generate hydrogen, thus skewing the data collected by the monitor. -

Installation Figure 3: LT Sample Probe + Tubing (1015-318) b. Unscrew the dust cap from the sample/purge valve on the rear panel of the InsuLogix The cap is tethered to the valve by a small chain to prevent loss or contamination of the cap caused by it falling on the ground c. - Page 13 Installation Note: Properly dispose of the ¼” tubing following installation as this tubing is intended for one time use only. Reuse of tubing may contaminate future oil samples. 24 in lengths of this tubing are sold as accessories under part number 2016-324. INSULOGIX-G2-IG-EN-V02 December 2023...

Page 15: Connecting Input Power
In the interest of separation of voltages, it is recommended to use the top gland fitting for the input power connection. Once input power is connected and if other wiring connections are to be made to the InsuLogix G2 at this time, do not turn on the power to the monitor yet. -
Page 16: Wiring The Relay Outputs
Installation Figure 6: Input Power Connection Wiring the Relay Outputs Twelve (12) programmable Form C relay outputs are provided to allow for hard-wired signals to an RTU or Supervisory Control and Data Acquisition (SCADA) system. Signal Relays (1-8) The signal relays are found along the side of the Main PCB. Figure 7: Signal Relay Location The orientation of the signal relay (1-8) terminals is shown in the table below. -

Page 19: Wiring The Analog Output Module (Optional Component)
Figure 12: Analog Output Module (1015-315) Use only shielded twisted pair cables for connecting the InsuLogix G2 analog outputs to a data acquisition system. Use of a multi-pair cable is acceptable and, in many cases, will be preferred to reduce the number of cables pulled to the monitor’s gland fittings. -
Page 20: Figure 13: Analog Outputs Location
Installation Figure 13: Analog Outputs Location Connect the cable shield wire to the provided shield terminal for the associated output. When using a multi-pair cable, tie the shield wire to any of the shield connection points on the analog output module Note: The cable shield should be connected at one end only to avoid introducing a ground loop into the circuit. - Page 21 Installation INSULOGIX-G2-IG-EN-V02 December 2023...
