WARNING! REMOVE THE METER FROM ALL SOURCES OF VOLTAGE BEFORE MOUNTING!
Mounting the PowerScout 3
The PowerScout
™
3 must be installed in an approved electrical panel or enclosure using proper installation
practices according to the local electrical codes. For convenience of mounting, two mounting tabs are
provided on the PowerScout
™
3.
Mounting the PowerScout 18
Open the top cover of the case to expose four (.275”/ 7mm) mounting holes, one at each corner. Using the
appropriate screw for the material that the PowerScout
™
will be mounted to, screw the case to the mounting
surface. The location you mount the case must be able to support at least 3 lbs.
Wiring the Modbus
For the PowerScout
™
18 only, open the top cover of the case (if so equipped) by turning the two corner screws
counter-clockwise until loose. Set two rotary switches (on the circuit board near to the Modbus/RS-485
connector) to the Modbus address desired. These switches (on both the PowerScout
™
3 and PowerScout
™
18)
set the address for metering element “A.” Metering elements “B” through “F” will always have a Modbus
address that is one higher than the element before. For example, if the rotary address switches are set to 01
then metering element “A” register values will be accessed at Modbus address 01, metering element “B”
registers will be accessed at Modbus address 02, “C” at address 03, and so on.
On the PowerScout
™
3 and PowerScout
™
18, the rotary switches are 16 position hexadecimal switches. The
default factory setting is hex 01 (Modbus Address Decimal 01). 254 different Modbus addresses are allowed
from 01 (hex 01) to decimal 254 (hex FE). Addresses hex 00 (Decimal 00) and hex FB through hex FF (Decimal
251 through 255) are reserved for factory use. (See Appendix A for a decimal to hex conversion, if your
equipment is decimal based.) Each PowerScout
™
18 uses 6 Modbus address.
Next connect the Modbus wires to the connector in the meter. Use Diagram below.
