4.2.4 Thermal Overload Shutdown
SEC-1215UL is cooled by convection and does not have any thermal overload shut down.
SEC-1230UL and SEC-2415UL are cooled by convection and in addition, have a tempera-
ture controlled fan (9 in Figs 2.2 and 2.3) for forced air cooling. Two temperature sensors
mounted on the power transformer control the switching of the fan and over tempera-
ture shut down. The fan will be switched on by the first temperature sensor when the
power transformer reaches 60°C / 140°F. Hence, at lower loads, the fan may not cut in
and will be off. This is normal.
In case the fan fails or if the cooling is not adequate, the second temperature sensor will
shut down the unit if the power transformer reaches 105°C / 221°C. The Red LED will
switch off. The unit will automatically recover on removal of thermal overload condition.
!
CAUTION!
Keep the charger in a well ventilated, cool and open area. Do not block the
vent holes on the sides or the discharge openings of the cooling fan.

5.1 INSTALLATION
5.1.1 Location, Mounting & Safety
The charger is required to be installed in a safe, well ventilated and dry location. Please
see the details given under Section 1 - Safety Instructions.
Mount the charger using 4 screws.
5.1.2 Output Connectors
Refer to output terminals 5, 6, 7 and 8 in Figs 2.1 / 2.2 / 2.3. Each terminal consists of
tubular hole with set screw. Insert the wire end in the tubular hole and tighten the set
screw. The diameter of the tubular holes is as follows:
SEC-1215UL
SEC-2415UL / SEC-1230UL
5.1.3 Wires for Output Connection
To avoid polarity errors and possible damage, never use wires of only one color. Use Red
insulated wire(s) for Positive connection(s) and Black for Negative connection(s)
Recommended DC wire sizes are given below. The length in feet is the length of the pair
of the Positive and Negative DC wires from the charger to the battery / other DC load.
Recommended sizes will limit voltage drop to 2%:
