OPERATING THE AT30
2.4.

PERFORMING ROUTINE MAINTENANCE

High voltages appear at several points inside the AT30. Use extreme
caution when working inside the enclosure. 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(+/-).
2.4.1. Keep it clean
The AT30 charger 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 AT30 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 AT30, 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 AT30.
2.4.3. Check remote sense wiring (optional)
If you wired the AT30 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 AT30 displays the
error code E 06. The AT30 returns to local control, sensing the output
voltage at the charger output terminals (TB1+/-).
