2 RPS14 Mains Voltage Setting
Step 3: Change the voltage setting
Locate the mains inlet PCB. An issue 1 board is shown here – some early RPS14s were fitted with an issue C
PCB – please consult Allen & Heath technical support for information on changing the voltage setting for the
issue C units.
The mains voltage setting is selected by connecting the
appropriate transformer primary lead to the LIVETX terminal
on the PCB. The terminals PARK1 to PARK5 are not
connected to any circuits – they are simply used to store the
unused leads safely.
Select the correct lead for your required mains voltage by
referring to the table, and then swap its position with the
lead currently connected to the LIVETX terminal. The unit is
now set to operate at the new mains voltage, and the
previously used primary lead is safely stored on a PARK
terminal. If in any doubt about the mains voltage for your
area, contact your electricity supplier.
Step 4: Check the fuse rating
It may be necessary to change the mains fuse to suit the new mains voltage – see the following table:
AC~ mains input voltage Fuse type
100V – 120V ± 10%
220V – 240V ± 10%
T 10A L 250V 20mm
T 8A L 250V 20mm
The mains fuse is located on the rear of the RPS14 unit next to the MAINS INPUT connector. Switch off the
power supply and remove the mains lead plug from the MAINS INPUT socket. Check the fuse and replace with
one of the correct type if necessary
Step 5: Refit the cover
Check your work carefully, making sure the leads are properly seated on the terminals. Ensure that there is no
dirt or debris inside the unit. Replace the cover and secure with the 8x Torx screws.
The unit should be clearly re-labelled with the new operating voltage.
Step 6: Test
Connect the unit to a mains supply at the new voltage. Power up and check for correct operation.
