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.
See Figure 7.11 and Figure 7.13.
