Use the Battery Mid-point Monitoring kits from Eaton (seeSpare Parts on page 68) or equivalent.1 Connect a Mid-point Monitoring sense wire to the middle interconnecting linkon each string of batteries (see following diagram). Connect the wire from XH12A pin 1 to string 1, and so on. If there is an odd number of 2V cells per string then connect the sense wires tothe interconnecting link on the side of the central cell closer to the Commonbattery terminal.2 Tighten the terminals according to the battery supplier's/manufacturer'sinstallation instructions.3 Insulate any un-connected sense wires.4 Secure all sense wires to avoid any strain on the terminations."

The sensors have a standard 8m (26 feet) long RJ45 cable, already connected tothe supervisory module. Only the temperature sensor in the master dc power cabinet is used.If required, longer cables are available (see Worldwide Support on page 95) or you can makeup your own. We recommend a maximum cable length of 20m (65 feet) because of noiseconsiderations.The battery temperature sensor measures the ambient temperature around the batteries andis required for the temperature compensation control function (see Control FunctionDescriptions in the System Controller Operation Handbook).
