High Voltage Connections
4.3.1
P7, Three Phase In
P7 is a block of three high current screw terminals used to connect the three phase or
single phase supply to the Q-Drive. If a single phase supply is used then connections
'R' and 'S' should be used. The individual phases are identified by markings on the
circuit board just above the terminals.
4.3.2
P8, Earth Terminals
P8 is a block of three terminals, all connected to ground. These terminals should be used
to connect the earth wire from the three phase supply or transformer and an earth
connection to the motor. One of these terminals can also be used to connect an earth
bonding strap to the Q-Drive although there is an M4 stud just below these terminals
designed expressly for this purpose. All metal parts of the Q-Drive are bonded to this
stud and hence it is imperative that it is connected to ground. The earth terminals are
marked as 'EARTH' on the circuit board just above the terminals.
4.3.3
P9, Motor
P9 is used to connect the three phase output to the motor. As with P7 and P8 it uses high
current screw terminals, The output phases are marked just above the terminals and
should be connected to the corresponding phases at the motor.The standard connections
to an SEM motor plug are phase U to pin A, phase V to pin B, phase W to pin F, and
earth to pin E.
