Sterlco MDB Series Dryers - Manual (Page 18)

In addition to the safety devices listed above, these dehumidifying dryers are equipped with a line
cord plug. This allows the operator or maintenance personnel to unplug the system from its
power source and tag it out. The plug can then be tagged with any number of approved electrical
lockout tags available at most electrical supply stores.
Always disconnect and lockout all electrical power and pneumatic (i.e. compressed air)
sources prior to servicing or cleaning the dehumidifying dryer. Failure to do so may result
in serious injury. No one but the person who installed the lockout may remove it.
