7.11 Voltage Conversion Instructions
Quite often it is necessary to transport a unit to another
country. If so, it will be necessary to alter the operating
voltage of the unit to match the standard voltage used
there. For this reason a world-wide voltage map is
supplied (Fig. 7.30) as well as the following interconnect
diagram. (Note: On earlier units, this diagram is placed
on the interior of the bottom cover should this manual
not be readily available.)
In order to change the voltage, it is first necessary to
disconnect power and remove the bottom cover from the
unit.
Warning
When removing PSA-2/SA2 covers, always discharge
the unit as described in Section 7.5.
The voltage connections are made with push on
terminals. After the correct operating voltage has been
chosen and all leads properly identified, follow the
connect drawing (Fig. 7.29). Be sure to also make all
e necessary fuse changes (if needed).

NOTE:
THREE SETS OF JUMPERS MUST BE CHANGED. ONE SET ON
EACH LARGE POWER TRANSFORMER AND ONE SET ON THE
RELAY BOARD. A 20 AMP FUSE SHOULD BE USED ON 100
AND 120 VOLTS. FOR 200, 220 AND 240 VOLTS USE A 10 AMP
FUSE.
