Windy Nation 100 AMP DC Watt Meter - Manual (Page 6)

Watt Meter User Manual
Revision 1.0
connectors and wires chosen for use be appropriately sized and rated for the intended application and
attached in the manner recommended by their respective manufacturers.
CAUTION: Poor connections and or intermittent/loose connections can cause component damage.
3.1.1 Wiring
Always connect and disconnect power at the meter FIRST on whichever of the LOAD or SOURCE sides that
has the highest electrical inductance. Long wire runs, motors, generators, etc. can have considerable
inductance.
Only qualified individuals should assemble any high current connections. The Red SOURCE wire goes to
Positive (Plus +) battery or other device terminals and black to Negative (Minus -).

3.1.2 Connectors
The Watt Meter is supplied with un-terminated wires so you can use whatever connector you may prefer.
If you decide to attach connectors to the SOURCE and LOAD, it is strongly recommended that you only use
female connectors on batteries and other power sources to prevent connectors and bare metal contacts from
shorting together. For example, with female (socket) connectors on your battery you will want male (plug)
connectors on the meter SOURCE leads and female connectors on the meter LOAD leads.
The user is responsible for selecting connectors rated to handle the current and voltage expected in the
user’s application and to follow the instructions provided with the connectors to ensure best results.
3.2 P OWERING T HE M ETER
The Meter requires a power source providing a minimum of 4.0 VDC to operate. This can come from a power
source (battery or generator) on the LOAD or SOURCE side or from the auxiliary 3-pin SOURCE power input
connector.
