ADDENDUM: CLASS 3400/5000 METERS
The following list of procedures describes steps to be taken to ensure the Class
3400/5000 Meters are installed in accordance with ANSI C12.20 Certification
Standards.
Chapter 6.2 Main Power Board Connections
Addendum
1. Wire Entry: one ¾" conduit opening is located on the bottom of the unit
enclosure. This opening is used for bringing in MAINS power and for current
sensor wiring. Route the appropriate cabling to and through the respective
enclosure opening.
2. Installing the Class 3400/5000 protective earth ground: Connect an earth
ground wire to the Class 5000 protective earth ground lug with a torque of 7
N-m.
Ensure that there is metal on metal contact between the Meter housing and
conduit to provide a low impedance path to GND. This requires removing the
paint surrounding the conduit hole during installation. We recommend to use a
1-1/8" Spot Facer Drill Brush to remove the paint, as shown in Figure 1 below:
