Note: If wire-passing board outlet space is insufficient when all terminals on the control board
are wired, cut the knock-out hole on the lower cover for wire outlet. If a dangerous situation
occurs when the knock-out hole is cut for a purpose but not wire outlet, we will not bear any
responsibility.
