FIGURE 2-3. LCD POWER ON DEFAULTS
NOTE: Six keys with dual functions are labeled with both a command and a number. The com-
mand label is referred to when the unit is in command entry status; the number is
referred to when the unit is in data entry status.
4. Press VSET key. Verify bottom line of LCD reads Vset nn (where nn = voltage setting).
5. Connect a digital voltmeter (DVM) to the (+) and (–) terminals at either the front or rear
panel.
6. Use number keys to enter rated maximum voltage (e.g. for ABC 25-4DM, 25V is the rated
maximum voltage) and press ENTER. Output voltage will be displayed at bottom left of LCD.
7. Use
"
and
#
keys as necessary to adjust output precisely to rated maximum voltage. Ver-
ify DVM voltage reading agrees with displayed voltage on LCD within 0.01% of rated maxi-
mum (see Table 1-3). If the LCD reads VsetMAX= (value), you are entering a value higher
than the maximum voltage setting; see PAR. 3.3.11.
2.6 INSTALLATION
A bail located on the bottom of the unit can be utilized to raise the front of the unit about two
inches for ease of accessing the front panel keypad and LCD display. For rack mounting, refer
to Figures 1-2 and 1-3.
2.7 WIRING INSTRUCTIONS
Interconnections between an a-c power source and a power supply, and between the power
supply and its load are as critical as the interface between other types of electronic equipment.
If optimum performance is expected, certain rules for the interconnection of source, power sup-
ply and load must be observed by the user. These rules are described in detail in the following
paragraphs.
2.7.1 SAFETY GROUNDING
Local, national and international safety rules dictate the grounding of the metal cover and case
of any instrument connected to the a-c power source, when such grounding is an intrinsic part of
the safety aspect of the instrument. The ground terminal of the source power connector (Figure
2-2) is connected to the ABC chassis and the instructions below suggest wiring methods which
comply with these safety requirements; however, in the event that the specific installation for the
power system is different from the recommended wiring, it is the customer's responsibility to
ensure that all applicable electric codes for safety grounding requirements are met.
