2.4.8 Wiring the line power - TB1
Terminal block TB1 on the power supply board contains
connections for the line power to the XDP. Make these
connections only with wire that meets the following
specifications:
• Individual conductor gauge of 18 AWG minimum
(maximum current capacity of 12 Amps)
• Voltage rating of 600 volts minimum
• Insulation temperature rating of 105°C minimum
WARNING!
The rating of the wire insulation must be
at least 15°C above the expected ambient
temperature.
Refer to "Figure 8" on page 14 and complete the following
steps:
WARNING!
Before proceeding with the section, verify
that the line power has been turned off at the
external disconnect device.
1. Attach a cable or conduit with the three line power
conductors to a cable entry port on the XDP enclosure.
CAUTION!
Be sure that the input voltage complies
with the input power rating for the XDP
(see "Chapter 7. Specifications" on
page 37 ).
2. Connect the line power leads to terminal block J1
as follows:
a. Connect the
line power lead (black or brown)
to pin L on the power connector.
b. Connect the neutral power lead (white or blue)
to pin N on the power connector.
c. Connect the ground power lead (green or
green/yellow) to the chassis ground screw shown
in "Figure 8" on page 14 .
3. Make sure that the factory-installed jumper wire
at pin G on the power connector is secure.
This completes the wiring of the XDP. Proceed to
"Chapter 3. Operation" on page 15 , for instructions on
using the flow meter.
