1.
Ventilation is of prime importance. Check the area around the unit; be sure that nothing interferes
with the free flow of air through the unit.
2.
All equipment performs better when clean, since there is better heat dissipation. The power supply
should be blown out with low-pressure dry air to remove dust accumulations.
3.
Connections should be clean and tight. Discoloration of terminals or wire is an indication of loose or
corroded connections.
4.
Capacitors (both AC and DC) should be checked for oil leakage, case or seal rupture, etc. All screw
connections should be tightened or checked. DC capacitors over five years old or showing signs of
degradation should be removed and checked for excessive leakage and/or replaced.
5.
Float and equalize voltages should be checked and adjusted. See sections 2.2 & 2.3.
6.
If possible, the operation of current limit should be checked as excessive overload may be damaging.
7.
To insure accurate meter readings, they should be checked periodically against portable standards.
Meters may be adjusted with the zero-adjusting screw on the face of the meter. Use care in doing so.
