Change over to 230 VAC is simple.

Remove the PLA-800 from it's enclosure by removing the four (4)

thumbscrews on the front panel and slide the unit out by pulling on the front

grab handle.

Turn the PLA-800 over exposing the underneath chassis compartment. In the

lower right rear, from the front panel end, there is a four (4) pin terminal block

with push on connectors. You can count the pins on the block from 1 (one)

through 4 (four) in either direction. There are two black jumpers connecting

pins 1, 2, 3, and 4. Remove the two jumpers from their respective pins by

grabbing the insulated portion of the connector pins.

Replace ONE jumper back onto the terminal block, by pushing each end of the

jumper onto pins 2 and 3.

This completes the change over of the PLA-800 to 230 VAC.

For the PSL 1000 Power Supply change over follow these steps.

Remove the PSL 1000 from it's enclosure in the same way as the PLA-800.

Turn the power supply over, exposing the underneath chassis.

At the bottom left rear of the chassis is the same type four (4) pin terminal

block as in the PLA-800. Remove the two (2) jumpers and replace one (1)

jumper to pins 2 and 3.

Find the push on the terminal connected to chassis ground (green wire with

push-on terminal). Connect it to terminal 2 as well. (The same procedure was

used with the PLA-800 with the exception of the ground push-on connector.)

Next, you will change over pins located in the front underneath portion of the

power supply. You will see four (4) breaker overloads. Two (2) for 115 Volt

AC (10 AMP) and two (2) for 230 Volt AC (5 AMP). Pull the WHITE WIRE

connector from the 10 AMP Breaker and push it onto the 5 AMP Breaker. Do

the same for the BLACK WIRE connector. Make sure that the white wire is

attached to the breaker with the white wire already attached on the breaker.

The same for the black wire to the breaker with the black wire already attached.

This completes the internal change over for both the PLA-800 and the PSL

1000. Return the units back to their respective enclosures and replace the four

(4) thumbscrews securely.

Finally, replace the male connector on the line cord with an appropriate 230

VAC plug. Since there are many types of connectors for primary power, it is

recommended that you consult your local electrician or if you are familiar with

an existing plug arrangement already in operation, use the plug required. Make

sure that the GREEN wire in the line cord, normally used for ground at 115

VAC operation, now becomes the neutral for 230 VAC operation.
