3 Installation
WARNING! Disconnect power prior to installation. Any covers that may be displaced during the installation must be reinstalled before powering the unit. Mount the Energy Meter in an appropriate electrical enclosure near equipment to be monitored. Exposure to VFD harmonics may cause permanent damage to this device.

2. Use three #8 screws (not supplied) to mount the Energy Meter to the inside of the enclosure. See diagram of the underside of the Energy Meter (below).

3.1 Types of Mounting
The Energy Meter can be mounted in two ways: on standard 35 mm DIN rail or screw-mounted to the interior surface of the enclosure.
3.1.1 DIN Rail Mounting
1. Attach mounting clips to the underside of the Energy Meter by sliding them into the slots from the inside. The outside edge of the clip must be flush with the outside edge of the Energy Meter.
2. Snap the clips onto the DIN rail. See diagram of the underside of the Energy Meter (below).
Figure 3-1 - DIN Rail Mounting 3. To prevent horizontal shifting across the DIN rail, use two AV02 end stop clips.
3.1.2 Screw Mounting
1. Attach the mounting clips to the underside of the Energy Meter by sliding them into the slots from the outside. The screw hole must be exposed on the outside of the housing.

Figure 3-2 - Screw Mounting
3.2 Supported System Types
The Energy Meter Series has a number of different possible system wiring configurations (see Section 4, Wiring). To configure the meter, set the System Type via the User Interface or Modbus register 130 (if so equipped). The System Type tells the meter which of its current and voltage inputs are valid, which are to be ignored, and if neutral is connected. Setting the correct System Type prevents unwanted energy accumulation on unused inputs, selects the formula to calculate the Theoretical Maximum System Power, and determines which phase loss algorithm is to be used. The phase loss algorithm is configured as a percent of the Line-to-Line System Voltage (except when in System Type 10) and also calculates the expected Line to Neutral voltages for system types that have Neutral (12 & 40).

When moving down to a smaller energy, the meter will not allow the selection if it cannot find a pulse duration that will allow the pulse output to keep up with Theoretical Maximum System Power. When moving up to a larger energy, the meter will jump to the first value where it can find a valid solution.
8.3 Minimum Duration Time ­ Milliseconds per Pulse (mS/P)
This read-only value is set by the meter to the slowest duration (in mS per closure) that will keep up with the Theoretical Maximum System Power. The open time is greater than or equal to the closure time. The maximum Pulses Per Second (PPS) is shown in yellow.

8.4 MultiFlex I/O Board Pulse Limits - Standalone Version Only
The MultiFlex board can read pulses at a maximum of 5HZ or 5PPS. The Energy Meter is capable of pulsing faster than the 5PPS maximum that the MultiFlex board can read. Pulses should be greater than 80mS in length at a maximum rate of 5HZ: Do not exceed 5PPS. For Example:
· Values of 100, 250, or 500 will be read by the MultiFlex board. · Values of 50, 25, or 10 will not be read by the MultiFlex board.
