Additional Information
External relay at signal output V(X) (0-10V / PWM)
Using an external relay (art. no. 77502), a 0-10V/PWM output V(X)
(V1, V2) can be used to get a switching power of 230 VAC (I) or a
potential-free changeover contact (II). The external relay is activated
via the signal output (0V = "off" (0 VAC or opened or closed), 10V =
"on" (230 VAC or closed or opened).
1. Connect external 0-10V relay to signal output, e.g. V1.
2. Assign additional function to signal V1. See " Relay functions " on
page 41
3. Disable the speed control for the corresponding 0-10V / PWM out-
put (Off). See " Variant " on page 40
Electrical Terminals
For high-efficiency pumps with 0-10V / PWM signal input, the power can be provided (V1 / V2 parallel operation) over a
free relay.
The connection of the ground wire is made at the lower gray terminal block. The neutral conductor N is connected to ter-
minal block N. The PE protective conductor must be connected to the PE metal terminal block!
