Unit Interlocks
A unit interlock is provided with each plug-in unit. Unit interlocks
prevent units from being removed from or inserted into a vertical
section when the operator handle is in the ON/I position.
Units can also be locked out with a padlock preventing installation of
the unit into a vertical section. The lockout feature of the unit
interlock can be used with the operator handle in the ON/I or OFF/O
position.
