UMG 804 voltage connection wiring
The UMG 804 must be connected to
the voltage source being monitored.
The Voltage input terminal serves as
the both power source to the monitor
and voltage sensing. All phases that
are to be monitored must be connect-
ed. The current consumption of the
monitor will not exceed 0.2 A at any
operational voltage.
The monitor is fused internally but
additional fusing may be required
per local and national codes
.
Inline fuses are available from Janitza.
