Installing The

Power Supply

The power supply for the

DXP’s

main cabinet

(DXPSM)

and

expansion cabinet (DXPSX) are shipped separately and require some

installation. During your initial preparation, you made sure that the

DXP cabinet would be mounted no further than four feet away-from a

dedicated

117V

AC 15 AMP circuit, with a third-wire ground on a

standard electrical outlet. To avoid power fluctuations caused by other

electrical appliances, it’s best not to install anything but the DXP

system on the outlet. Always use an AC surge protector to protect the

DXP from fluctuations in the AC power. Since the AC power cord is

only four feet long, make sure to mount the surge protector on the left

side of the main cabinet.

Also, to avoid an accidental power loss, make sure the outlet doesn’t

have a switch to turn off power. After you have chosen your dedicated

outlet, always do a voltage check on the outlet before you plug in the

system. To check the voltage using an AC Volt meter, first check the

voltage between the neutral and the “hot” side of the outlet; the

reading should be between 90 and 129 VAC. If the voltage range is

beyond this specification, contact a qualified electrician immediately.

The power supply slides into the slot on the left side of the

cabinet; it has two openings which slide over the two metal

posts on the front of the DXP cabinet.

Attach the two hex-nuts through the slots on the front of the

power supply and into the DXP cabinet.

Install the remaining screw in the back of the power supply

and into the cabinet. Route the power cord through the slot on

the side of the cabinet. (for more information on the main

cabinet power supply, see

IMI66-085.)

Remember to connect the power to a surge protector and not

directly to an outlet.
