Connecting a junction box Drummotor
with an internal backstop (TBLH/TBRH)
1. Observe the arrow on the end fl ange of the drum. This indicates the direction of 'free'
rotation of the Drummotor (refer to Fig. 2).
2. Ensure a correct earth connection.
3. Connect the terminal board in star or delta according to the supply voltage and the
information on the Drummotor data plate.
4. Connect the three phase (3PH) supply as follows: Connect L1 to U1 of the terminal board,
connect L2 to V1 and L3 to W1.
5. Switch the power supply on for no longer than 1/2 second. If the Drummotor turns, the
phase rotation is correct. If the Drummotor does not turn, switch off immediately and
reverse two phases; Eg: Connect L1 to V1 and L2 to U1.
6. Switch the power supply back on. The Drummotor will now run in the correct direction.
Connecting a cable Drummotor
with an internal backstop (TBLH/TBRH)
1. Observe the arrow on the end fl ange of the drum. This indicates the direction of 'free'
rotation of the Drummotor (refer to Fig. 2).
2. The cores are coded with numbers. For these codings refer to the drawings on page 31-32.
3. Ensure a correct earth connection.
4. Connect the power supply to the cores according to the correct drawing.
5. Switch the power supply on for no longer than 1/2 second. If the Drummotor turns, the
phase rotation is correct. If the Drummotor does not turn, switch off immediately and
reverse two phases; Eg: L1 and L2.
6. Switch the power supply back on. The Drummotor will now run in the correct direction.
