14. CONNECTION, TESTING AND USE
Connection : The unit can be connected as shown on drawing 15.
Make sure your assembly complies with the local safety regulations. For
improved safety, use a non-conductive enclosure.
Enclosure :
Drawing 17 provides a drill pattern for our optional enclosure (ref.
TKAUS22G). The included adhesive front panel label can be used to mark
the position of the holes to be drilled. Position the label on the front panel
and fix it temporary with tape. Mark the center of the holes with a center
punch. Remove the label and drill the holes. Pay attention to the correct di-
ameter. Make sure all holes are free of burrs. Degrease the front panel be-
fore sticking the label onto it. The label edges will need to be trimmed with a
sharp cutter. Drawing 16 provides an internal view of the finished unit.
Whatever enclosure you use, make sure it is well ventilated, as the heatsink
might run hot during charging.
Testing :
Perform all tests as shown below, before the first use of the unit. It allows
you to check every function of your charger kit. Use the supplied 5W dummy
load resistors and a reliable multi-meter.
