IS Power Supply Unit Mains Voltage Default Setting
The IS Mains Operated Power Supply Unit is shipped set for 230v AC operation
and will not self-adjust for 115 AC operation
.
If 115v AC operation is required then set the internal slide switch to the 115V setting.
Changing the supply voltage may be accomplished by first ensuring mains power is not
applied to the Power Supply box.
Open the Power Supply box lid.
Remove 4 screws and washers retaining the protective Perspex cover over the PSU pcb.
Remove the Perspex cover and then set the slide switch to the appropriate voltage
position.
Reverse the above to re-assemble the unit the lid screws should be torqued to 2NM.
