INSTALLER'S INSTRUCTIONS FOR
IMPORTANT: The wiring installation for this meter, especially the shunt installation
must be performed by someone knowledgeable on proper wiring, electrical practices,
and safety. If you do not have this knowledge please have someone install it who does,
or at least get some competent help to supervise the installation.
To install:
1. Please read or scan two pages of introductory information in section A.
2. Consult drawings Figure 1 and 2 (pages 7-8).
3. Follow step by step installation instructions in section B.
4. Install at least 3 important numbers into meter as described in section C.
A. Meter Installation: Preliminary: What you need to know before
installing the TriMetric meter
B. Meter and Shunt Installation: How to make connections from meter to
battery and shunt.
C1. Entering required three setpoints in TriMetric memory: How to
enter necessary data related to your battery system to make the TriMetric
displays give you the correct information.
C2. Information on the next (optional) three program setpoints.
Limited warranty. Meter is warranted for 1 year against any manufacturing defects. Any meter not meeting
the specification or performance description will be replaced or repaired within one year of purchase, provided it
has not been subject to abuse or misapplication, and provided the defective unit is shipped to us if we request it.
Contact your dealer or us before shipping.

- Page 1 INSTALLER’S INSTRUCTIONS FOR TRI-METRIC Battery system monitor, Model TM-2025-RV revised March 14, 2009 IMPORTANT: The wiring installation for this meter, especially the shunt installation must be performed by someone knowledgeable on proper wiring, electrical practices, and safety. If you do not have this knowledge please have someone install it who does, or at least get some competent help to supervise the installation.
- Page 2 A: METER INSTALLATION--PRELIMINARY: Useful information to review before installing. Choosing meter location and some benefits of battery monitoring: To make best use of this monitor, we recommend that it be located where it can be readily observed in the living area where the electrical power is used, such as a kitchen or living room.
- Page 3 "100 amp" shunts will not carry this much without overheating--especially some of the "mini" shunts of this type. For more information, request : "Information on Shunts" from Bogart Engineering, or get it from the internet address shown on page 1 If it is desired to measure only total solar input current, or only total load current (and amp-hours): you must wire the shunt such that only the solar current, or load current will pass through the shunt.
- Page 4 To install meter and shunt you will need: • One shunt (usually 500A/50mV size) • A length of cable containing 4 or 5 wires long enough to connect from battery system to meter. Or 4 or 5 individual wires may be used. (Five wires if two batteries are being measured.) The wire used for the + connection of the battery should have a 2A fuse at the battery end to protect the wire in case of a short.
- Page 5 (These two wires must join together only right at this terminal.) Then connect the SIG wire to the other Kelvin connection, closer to the minus battery connection. STEP 5: Connect the fuse holder to the battery + terminal, but don't yet put in the fuse. Connect the + wire from the fuse to the TriMetric + terminal.
- Page 6 How to determine value for program item P2: “charged setpoint amps” Just take the value you found for P3 above and multiply it by 2, then divide the result by 100—to give a value in amperes. Put this value in “charged setpoint amps” (P2) in Table 1. Now that you have these three values program them into the TriMetric as described at the bottom of page 6.
