The MOTM-900 Power Supply is a UL/CSA/CE approved linear regulator for powering up to 22 MOTM modules. Input voltages from 100VAC to 240VAC can be used with the proper wiring. Power to each module is by a 4-conductor 18ga. jumper cable, that plugs into the power distribution board.

Slide the smaller terminal on the lower right power switch connector. PHASE 2: Wiring to the power supply The MOTM-900 uses a pre-assembled, pre-tested Power One linear supply. It attaches to the front panel using 2 #8-32 x 3/8 black screws and 2 #8 KEPS nuts.
Note that for 220-240V, the two existing jumpers are cut off, and one jumper is added, using the supplied wire. DANGER! THE AC INPUT TERMINALS CARRY LETHAL VOLTAGES WHEN POWER IS ON. NEVER WORK ON THE POWER SUPPLY WITH THE AC LINE CORD PLUGGED IN. SYNTHESIS TECHNOLOGY PAGE 5 MOTM-900 ASSEMBLY 6/26/03 WWW.SYNTHTECH.COM...

Now comes the hardest (and most critical!) part of the kit: soldering the 3 wires from the power distribution board to the Power One terminals. Why? Because if these connections are not secure, all of the modules will loose power. SYNTHESIS TECHNOLOGY PAGE 6 MOTM-900 ASSEMBLY 6/26/03 WWW.SYNTHTECH.COM...

Carefully inspect each joint. Make sure the solder is on all sides of the terminal. Don’t put so much solder on that it looks like a pyramid. Put a nylon tie-wrap around the 3 wires about in the middle. SYNTHESIS TECHNOLOGY PAGE 7 MOTM-900 ASSEMBLY 6/26/03 WWW.SYNTHTECH.COM...

4) Look at the chart for the transformer wiring. Carefully verify that the transformer is properly jumpered for your country. If you have a DVM or voltmeter, you can check to see if the MOTM-900 is outputting the correct voltage: + and -15VDC.
