Electrical system
The figure below illustrates the electrical connections for the control unit on the
electric motor.
Figure: Electrical schematic for HAPP motors.
HAPP motors are supplied with an additional connector that bridges the A2 connector
as shown below allowing a limit switch to be configured. If this connection is not
required the connection is bridged, insulated and put inside the control box. This
connector must be covered with insulation tape to provide a 2
nd
level of insulation if
used or two levels of heat shrink and insulation tape used to insulate connections. A
fuse-able 4A link must be in place at contactor if not already supplied. A third wire that
earths to the connection to motor and limit switch must be fitted. Ensure all electrical
work is signed of by a qualified electrician.
