Status Inputs
Up to four dry (non-powered) contacts can be connected to the
PowerMonitor 5000 unit status inputs. The status input derives 24V DC 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 the contact
end only. The diagram indicates typical status input wiring.
