2.7.7 Control power terminals
The main circuit terminals R/L1 and S/L2 are internally connected with R1/L11 and S1/L21 (control
power terminals in the lower low). By default, the lower terminal block is connected with the upper
terminal block (control power terminals) via short bars; the control power is turned on at the same
time as the main circuit power is turned on. To keep the control power active at the time of error
detection, remove both short bars (shown below) and provide the control power separately.
(1) Remove the lid.
(2) Remove the screws.
(3) Remove the short bars.
