Note: The supply circuit in the RM1E..V versions is provided with reverse pro-

tection in case the female connector is reversed so as to have a reverse volt-

age applied to terminals A1-A3. No reverse protection is provided on the con-

trol and hence the terminal markings indicated should be respected to avoid

any damage to the device.
