• Be sure to connect pin number 5 (SG) of COM1 to the host unit's

Signal Ground terminal.

• Be sure to confirm what settings will be used by the other

device and set the dip switches accordingly. Failure to do so can

result in a unit malfunction or damage.

• Whenever changing the PS-A switches, be sure to first turn the

PS-A's power supply OFF. Failure to do so can cause a PS-A

malfunction.

• Connect the FG terminal line to the connector cover's PS-A con-

nector attachment screw.

• FG and SG terminals are internally connected in the PS-A. When

connecting to another device, be sure to create an SG shorting

loop in your system.

Use inch type (#4-40UNC) threads to hold the cable's set (attachment) screws

in place.
