The monitor output from the unit is a through a Deutsch brand connector P/N: HDP24-18-14PN.
The mating connector is the Deutsch P/N: HDP26-18-14SN housing with Deutsch P/N: 1062-16-
0622 socket contact.
Remote Sense (Terminals M, N, and P)
There are three inputs for this function, +24, +12, and ground. They are for remote sense of the battery
voltage. This makes the Equalize function insensitive to wire, fuse and connection voltage drops. All three
sense lines must be connected for this function to work properly. It is usual for the battery connections to
be brought to a distribution point from where connections are made to the rest of the vehicle. Since the
battery charge current is the only current which the battery cables carry for most of the time it is
convenient to connect the sense wires to these distribution points. This should not introduce a significant
error. In fact, when the system stabilizes and the batteries are charged there will be almost no error.
The sense wires can be 16 or 18AWG as the input impedance is high, and the wire gauge can be set for
mechanical strength requirements. This allows cost savings and freedom of configuration in the Equalizer
power connection wiring, and more freedom in Equalizer location. The equalizer current carrying wire
gauge can be the minimum size listed in this manual's wire size table for a given Equalizer rating, up to
four times the distance listed. This sets a maximum voltage drop of 0.4V which is reasonable from
efficiency and fault detection considerations.
