2.2.6 Operating slide switches
Operation of the various switches should be conducted
after more than
5 minutes has elapsed
since power
is shut off
for types smaller than FRN0069E2
-2
and FRN0072E2
-4
and
after more than 10 minutes
has elapsed for types larger than FRN0085E2
-4
. Confirm that the LED monitor and the charge lamp are
turned off, and that the direct current intermediate circuit voltage between the main circuit terminals P(+) - N(-)
is below the safe voltage (below DC+25 V) with the tester before operating the switches.
Risk of electric shock exists.
The I/O terminal specification can be changed, such as switching the analog output form, by operating the various
slide switches on the printed circuit board (Figure 2.2-22 Slide Switches Positions on the Control Printed Circuit
Board).
To operate the various slide switches, remove the front cover and make the control printed circuit board visible.
(For types larger than FRN0085E2
-4
, also open the keypad case).
Refer to Section 2.2.2 "Removal and attachment of the front cover and wiring guide" to remove the front
cover and to open/close the keypad case.
The slide switches positions on the control printed circuit board are shown below.

Use pointed devices (such as tweezers) to operate the switches. Avoid touching other electronic parts
when moving the switches. The switch will be at open state when the slider is in the middle, so make
sure to push the slider to the ends.
