INSTALLING THE AT30

1.11. INSTALLING THE TEMPCO PROBE ASSEMBLY (OPTIONAL)
The temperature compensation probe contains a temperature-dependent
resistor in an epoxy module that you install near your battery. There are
three steps in installing the assembly:
1. Mounting the probe assembly near the battery.
2. Installing an interconnection cable from the probe assembly to the AT30.
3. Wiring the charger end of the cable to a terminal block on the main control
circuit board.
The actual tempco probe is the same for all battery types and all output
voltages of the AT30. The accessory part numbers differ depending on
cable length ordered. See the tables in Appendix B on page 65 for
ordering information. Each kit contains detailed installation instructions
(
JA5015-00
). The main elements of the installation are outlined below.
WARNING
High voltages appear at several points inside the AT30. Use extreme
caution when working inside the unit. Do not attempt to work inside the
AT30 unless you are a qualified technician or electrician.
Disconnect and lock out all power from the AT30 before starting to
remove or replace any components. Turn the ac power off at the
distribution panel upstream from the charger. Disconnect the battery
from the AT30 output terminals TB1(+/-).
PROCEDURE
1. De-energize and lock out all ac and dc voltage sources to the AT30, and
check with a voltmeter before proceeding.
2. Mount the probe on a clean, dry surface, as close to the battery as possible,
such as the battery rack. DO NOT mount the probe:
•
on the battery itself
•
on unpainted wood, or bare galvanized metal.
•
on plastic surfaces
3. To apply the probe, clean the mounting surface with isopropyl alcohol, and
allow to dry thoroughly. Remove the protective backing from the double-
faced adhesive tape on the probe, and securely press it onto the surface.
4. Install the cable supplied with the temperature compensation probe kit:
•
Start at the AT30 charger. The end of the cable with two stripped wires
and one lead with a quick-connect terminal will be connected inside the
AT30. Leave 30in / 762mm of cable inside the enclosure, and route the
other end to the probe at the battery.
