Introduction:
This Quick Installation Guide is for the installation
of the Tobi Wi-Z only. See the Tobi Wi-Z Software
User Guide for instructions on programming and
calibrating the Tobi Wi-Z.
The installation of the Tobi will require a means to
calibrate the current on site. This requires a
computer located within 100 feet of the Tobi PI Wi-
Z with the TOBi™ Wi-Z software installed and the
Tobi Wi-Z USB coordinator.
Additionally, a means to verify charger amperage
output is needed to complete current calibration.
This can be accomplished by using an accurate
digital ammeter on the charger or a handheld amp
probe.
Required Tools
Installing the TOBi™ PI Wi-Z will require the following
tools:
Portable drill
5/32” drill bit- titanium coated preferred
1/2” drill bit
5/16” nut driver or socket
Side cutters

Hardware Installation
There are 8 leads coming from the Tobi PI Wi-Z:
1. Negative Post (black wire)
2. Current Shunt (brown wire)
3. Current Shunt (orange wire)
4. Strap Thermistor (black wires with ring terminal)
5. 12V Post ( blue wire)
6. Water Level Probe ( with lead probe
and grommet at the end)
7. Cell Thermistor ( thick black cable with black
probe and grommet at the end)
8. Positive Post (red wire)
1. Attach the BLACK wire to the negative post of the
battery by first drilling a 5/32” pilot hole in the center
of the post. Attach the ring terminal of the lead to the
battery terminal using one of the provided stainless
steel screws and tighten using a 5/16” nut driver or
socket.
2. Attach the BROWN wire to the positive post of the
first cell from battery negative by first drilling a 5/32”
pilot hole in the center of the post. Attach the ring
terminal of the lead to the battery terminal using one
of the provided stainless steel screws and tighten
using a 5/16” nut driver or socket.
3. Attach the ORANGE wire to the negative post of the
second cell from battery negative on the same strap
as the brown wire by first drilling a 5/32” pilot hole in
the center of the post. Attach the ring terminal of the
lead to the battery terminal using one of the provided
stainless steel screws and tighten using a 5/16” nut
driver or socket.

4. Attach the strap thermistor to the strap halfway
between the BROWN and ORANGE wires by first
drilling a 5/32” pilot hole in the strap. Attach the ring
terminal of the thermistor to the strap using one of the
provided stainless steel screws and tighten using a
5/16” nut driver or socket.
5. Attach the BLUE wire to the positive post or strap of
the 6th battery cell from the negative post of the
battery (12V) by first drilling a 5/32” pilot hole in the
center of the inter-cell connector strap. Attach the
ring terminal of the lead to the strap using one of the
provided stainless steel screws and tighten using a
5/16” nut driver or socket.
6. Attach the RED wire to the positive post of the battery
by first drilling a 5/32” pilot hole in the center of the
post. Attach the ring terminal of the lead to the battery
terminal using one of the provided stainless steel
screws and tighten using a 5/16” nut driver or socket.
7. Drill a ½” hole in the lid of one of the cells near the
center of the battery (refer to figure 2). Choose a cell
that is at least 4 cells from the negative post of the
battery (>8V). Ensure the area under the cell lid is
clear to the moss shield before drilling. Trim the lead
water probe using wire cutters so that the tip will be
approximately 1/8” above the moss shield after
installing the probe. Press the probe grommet into
the hole.
8. Drill a ½” hole in the lid of another cell near the center
of the battery (refer to figure 2). Ensure the area
under the cell lid is clear to the moss shield before
drilling. Adjust the thermistor cable in the grommet so
that the probe will be just above the moss shield after
installing the thermistor. DO NOT CUT THE
THERMISTOR. Press the probe grommet into the
hole.

9. Secure the Tobi to the battery, strap, or cable in a
convenient location. The ideal location is set between
two inter-cell straps. Secure the Tobi tightly against
the inter-cell straps. Tighten using two provided cable
ties.
10. Use the remaining cable ties to secure any loose
wires to prevent damage.

The Tobi Wi-Z transfers data from the memory to a PC via
wireless communication. It operates at 2.4 GHz on 802.15.4 and
auto-selects from 16 available channels to set-up a network to
communicate with the PC. The Tobi PI Wi-Z works independently
of other wireless networks in your facility and will not interfere
with existing Wi-Fi networks. The rated distance for data transfer
is 100 feet from the Tobi PI Wi-Z to the PC. Each Tobi PI Wi-Z
acts as a wireless router so a daisy- chain effect is possible with
multiple Tobi PI Wi-Z devices.
The Tobi PI Wi-Z has 1 indicator LED for water level.

The mechanical installation of the Tobi PI Wi-Z is now
complete. You are ready to calibrate the current sensor and
enter battery data into the system. Please refer to the Tobi
Wi-Z Software User Guide for instructions on calibrating
and initializing your new Tobi PI Wi-Z.
This device complies with part 15 of the FCC rules.
Operation is subject to the following two conditions. (1) This
device may not cause harmful interference. (2) This device
must accept any interference received, including interference
that may cause undesired operation.
WARNING: To satisfy FCC RF exposure requirements for
mobile transmitting devices, a separation distance of 20cm
or more should be maintained between the antenna of this
device and persons during operation. To ensure compliance,
operations at closer distances than this are not
recommended.
