Voltage connection components
The voltage connection supplies power and provides a reference signal for the monitoring module. The voltage connection needs to be made safely, on a de-energized system, in accordance with specifications of the target equipment and local electrical codes.
The voltage connection harness is modular and consists of the following parts:
(optional)
When installed, the wire harness components are daisy chained in the following order, from the voltage source to the module:
-
WHA-V (required) provides connection to the voltage source, in most cases a dedicated multi-phase breaker
-
WHA-X (optional) provides an extension if needed
-
WHA-F (required) provides fusing
-
WHA-M provides connection to the monitoring module and power supply
Voltage connection installation
In most cases the voltage connection harness (WHA-V) is connected to a dedicated, multi-phase circuit breaker.
The following diagram illustrates the complete voltage connection for an HDPM system.
