The Bosch dryer comes with 4-wire power supply cord
pre-installed. This cord fits a 4-wire receptacle as shown
in the upper section of Figure 11.
If your receptacle is a 3-wire receptacle, as shown in the
lower section of Figure 1, a 3-wire ‘‘Dryer Cord’’ must be
purchased locally. The 4-wire cord must then be
removed and the 3-wire cord installed in its place.
Electrical Connection, 4-Wire
For a 4-wire system, all that is necessary is to plug
the 4-wire power supply cord into the 4-wire receptacle
of the proper rating.
Note: The receptacle should be located so that the plug
and receptacle will be accessible when the dryer
is in its final installed position.
Electrical Connection, 3-Wire
If your receptacle is a 3-wire receptacle as shown below,
Figure 19, you must obtain a 3-wire dryer cord. Dryer
cord can usually be found at your local hardware supply,
electrical supply or home center. Cord should have
closed loop or upturned end wire terminating connectors.

terminal.
4. Remove the red, white and black wire from the
terminal block.
5. Loosen the 2 screws in the U.L. strain relief clamp,
holding the 4-wire cable.
