!
WARNING
High voltages appear at several points inside the AT10.1. Use extreme
caution when working inside the enclosure. Do not attempt to work
inside the AT10.1 unless you are a qualified technician or electrician.
Disconnect and lock out all power from the AT10.1 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 AT10.1 output terminals TB1(+/-).
2.4.1. Keep it clean
The AT10.1 is cooled by natural convection. At least once a year,
vacuum the vents at the top and bottom of the enclosure to ensure that
there is an adequate supply of cooling air. If you have an extremely dusty
environment (especially if airborne dust is conductive),
carefully vacuum
out the interior. Clean the surfaces of circuit boards, and clean around
electrical terminals.
The AT10.1 is rated for operation up to 122 °F / 50 °C. If your
installation is in a warmer environment, or at an elevation over 3000ft /
914m, contact your sales representative for operating information.
2.4.2. Check power and signal connections
Check the tightness of all field connections inside the AT10.1, and
connections to the battery. A loose or corroded connection at the battery
terminals can be a fire or explosion hazard, and may cause erroneous
operation of the AT10.1.
2.4.3. Check remote sense wiring (optional)
If you wired the AT10.1 for remote sense, check the signal connections to
the battery or load, making sure insulation is in satisfactory condition. If
there is a failure of the remote sense signal wiring, the AT10.1 displays
the error code
E 06
. The AT10.1 returns to local control, sensing the
output voltage at the charger output terminals (TB1+/-).
