Mounting the BU cover
Introduction
BU covers are plugged onto BaseUnits whose slots have been reserved for future expansion
(as empty slots). The BU covers for motor starters serve as touch protection covers for
unoccupied slots.
DANGER
Hazardous Voltage
Can Cause Death, Serious Injury, or Property Damage.
Hazardous electrical voltage causes electric shock, burns and property damage.
Disconnect your system and devices from the power supply before starting any assembly
tasks.
DANGER
BaseUnit without motor starter - electric shock
If you install a BaseUnit without motor starter in the ET 200SP system (e.g. options
handling), you must provide the BaseUnit with a BU cover (Article No: 3RK1908-1CA00-
0BP0).
Failure to do so will result in the danger of electric shock.
Procedure
To mount the BU cover onto a SIMATIC ET 200SP motor starter, insert the BU cover in the
BaseUnit in parallel until both interlocks audibly engage.
