Installation and Operation Instructions
INTRODUCTION
Use these instructions to assemble the NEW ERA METER. Read all instructions before
you begin the installation.
The NEW ERA METER is designed for a variety of metering configurations. It can be used as a stand-alone NEW ERA METER™, part of an automated dial-up system or a stand-alone device.
All information required to install a stand-alone NEW ERA METER is given in these
Installation Instructions and on the diagram inside the meter enclosure. If this meter is to be used with an automated system using WIFI, Ethernet or 485 interface, refer to the NEW ERA
METER™ Installation Manual for additional installation instructions.

INSTALLATION
This section gives instructions for assembling and installing the NEW ERA METER as a stand-alone unit. The NEW ERA METER should be installed only by a qualified electrician.
These instructions are not intended to control the interface between this product and the facility wiring. Compliance with NEC and local codes in the final applications should be verified by the local inspection authorities. If equipment is used in a manner not specified by
Global Power Products, the protection provided by equipment may be impaired.

NOTE: The NEW ERA METER is equipped with one hole in the bottom of the box to accommodate
3/4” conduit. If connecting from the bottom is inconvenient, remove the electronics and drill holes in only in the lower half of the box. The upper portion of the box is used to accommodate the circuit boards.
- Select a mounting location at a minimum of 18” off of the floor.
Step 1 Mount enclosure by the three mounting tabs found on the back of the enclosure using mounting hardware appropriate for the mounting
surface.
If needed, drill a hole in lower half of
enclosure approximately 2 inches
up from the bottom, only after
removing the electronics.
Figure 1, NEW ERA METER Enclosure
Step 2
Connect conduit to load center (or switchgear) and to enclosure.
Refer to Figure 2 for steps 3 through 5
Step 3 Install Current Transformers.
Current Transformers can be used on the incoming lines or on individual breakers. The dot on the Current Transformer always faces the line or supply side of the service.

Step 4 Make Voltage, neutral, and grounding taps. a) Make sure service is disconnected before make any connections b) Using in-line fuses, tap each of the phases according to all applicable electric codes. c) Secure one end of a grounding lead to earth ground in the breaker panel or meter board. d) Attach a lead to the neutral terminal in the breaker panel or meter panel. e) Run voltage taps along with a secured neutral and ground tap through the conduit to the meter.
Step 5 Referring to the wiring diagram on the inside of the meter cover, terminate CT, voltage, ground, and neutral leads. See Figure 3 for a 3 Phase 4
Wire Wye or 4 Wire Delta service and Figure 4 for a 3 Phase 3 Wire Service. a) Attach ground lead to the lower left grounding point on the circuit board using the enclosed grounding washer and screw. b) Now you are ready to install the terminal blocks. The terminal blocks (TB1 and TB2) found in the hardware kit should be installed on the lower section of the of the board. The four terminal voltage connection block (TB1) goes on the lower left side of the board. The six-terminal current transformer connection block (TB2) goes on the lower right side of the board. c) Using the wiring diagram found on the inside of the meter cover, make the appropriate voltage and current lead connections. Refer to Figure 3 for a wiring diagram for a 3-Phase 4-Wire Wye or Delta service and Figure 4 for a 3-Phase 3-Wire Delta service. d) Align each terminal block with the pins and header on the circuit board and gently push the terminal block into place.

CAUTION
Do not mix the phases of the voltage and current leads. For example, Phase A voltage tap should match phase A Current Transformer leads. Incorrect metering will result, as well as an error being displayed if the leads are improperly connected.
Step 6
Close cover and Seal: a) Install the two captive screws in the right hand side of the enclosure cover. b) Install the wire seal in the cover latch. c) Remove any protective covering on the face of the meter.

Installation Diagnostics
Upon power-up the NEW ERA METER series meters operates in the Normal display mode. The display continuously scrolls through the Normal display sequence, displaying each selected quantity, annunciator, and any other programmed parameter. The meter will operate in Normal Mode until power is disconnected, the
Alternate display sequence is initiated, the Test Mode is accessed or the Toolbox Mode is accessed.
Test Mode can be accessed using a small magnet (30 gauss) near the reed switch. The reed switch is
located in the one o’clock position just above the nameplate.
TESTING
There are several ways to test a NEW ERA METER. The following table lists different testing methods and the equipment required.
Testing Method Location Requirements
Infrared Test LED
Pulse Initiator Outputs
Located on face of meter
Meter must have KYZ Outputs
Disk Emulation Annunciator
LCD Display
Optical Pick-up, Standard &
Comparator
Standard & Comparator
No Additional Equipment
Most field accuracy tests will utilize the Disk Emulator on the bottom of the LCD Display, therefore this method will be described in detail.
The NEW ERA METER is equipped with a bi-directional Liquid Crystal Display (LCD) watt-hour disk emulation annunciator. The disk emulation annunciator consists of four segments located in the lower left portion of the display. The NEW ERA METER uses internal multipliers to compensate for current transformers larger than 200 Amps.
If your meter is equipped with Time Of Use, Extended Functions or Demand Threshold Outputs, a data sheet of the parameters displayed will be included for all three modes of operation.
MODES OF OPERATION
NORMAL MODE
An NEW ERA METER operates in two modes a “NORMAL” mode and a “TEST” mode. The meter powers-up and runs in the NORMAL mode. This is indicated when the “TEST” indicator is not on, as in the figure below;
When the arrow in the lower left corner increments to the right, it indicates the meter is accumulating properly. And the center letters indicates the meter parameters are being displayed. In this case Total kWh is displayed.

TEST MODE
The individual NEW ERA METER in a can be put in a diagnostic “TEST” mode by placing a magnet to the right of the display. The meter will sequentially display the voltage, the current and the instantaneous Power for each phase. If a communication module it attached, such as the RS485, the meter will display the programmed ID number, Com ID, and Baud Rate. In addition, the meter will also display Serial Number, Current Transformer Size, Power Outage
Monitoring , and Demand Reset Monitoring.
Test Mode Tool Placement location. The NEW ERA
METER will go into a test mode when a magnet is placed on the surface of the meter.
Error Mode
If the individual NEW ERA METER detects an error in the wiring “ERROR” will be displayed in the lower left corner of the LCD.
