One or two dry (non-powered) contacts can be connected to the power monitor status inputs.
The power monitor 24V DC status input derives power from its internal power supply.
Connect status inputs by using shielded, twisted-pair cable with the shield connected to the
ground bus or other low-impedance earth ground at one end only. The diagram indicates typical
