5.3 Circuit diagrams
Belt grinding machines can be connected to 3 x 400/440 V, 50/60 cycles and to 3
x 230 V 50/60 cycles. There is three kinds of circuit diagrams:
1. One velocity grinder without brakes see 4.3.1 and 4.3.2
2. One velocity grinder with brakes see 4.3.3 and 4.3.4
3. Two velocity grinder with no brakes see 4.3.5 and 4.3.6
When the motor is for 3x480 V utilize same diagrams as for 3x400/440.
