All Multronic relay contacts are potential-free contacts.
If relay outputs are also needed for measurement modules 2 and 3, an additional relay
module must be installed (see section 5.2.2).
Clamp 7/8
Clamp 9/10 (not available at Multronic OC)
Clamp 11/12 (not available at Multronic OC)
When connecting the power outputs, pay careful attention to the correct polarity and the
maximum load (600 Ω).
