INSTALLATION
WARNING: TO AVOID FIRE, SHOCK, OR DEATH, disconnect power
prior to installation.
Reinstall any covers that are displaced during the installation before
powering the unit.
Mount the meter in an appropriate electrical enclosure near
equipment to be monitored.
Do not install on the load side of a Variable Frequency Drive (VFD).
For all S4100 Series (bidirectional) models, observe correct CT orientation.
The meter can be mounted in two ways: on standard 35 mm DIN rail or screw-mounted to
the back of the enclosure.
A. DIN Rail Mounting
1. Attach mounting clips to the
underside of the housing by sliding
them into the slots from the inside.
The stopping pegs must face the
housing, and the outside edge
of the clip must be flush with the
outside edge of the housing.
2. Snap the clips onto the DIN rail.
See diagram of the underside of
the meter.
3. To reduce horizontal shifting
across the DIN rail, use two end
stop clips.
B. Screw Mounting
1. Attach the mounting clips to the
underside of the housing by
sliding them into the slots from the
outside. The stopping pegs must
face the housing, and the screw
hole must be exposed on the
outside of the housing.
2. Use three #8 screws (not supplied)
to mount the meter to the back of
the enclosure. See diagram of the
underside of the meter.

SUPPORTED SYSTEM TYPES
The meter has a number of different possible system wiring configurations (see Wiring
Diagrams, page 9-10). To configure the meter, set the System Type via the User Interface,
Modbus register 130. 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).
Values that are not valid in a particular System Type will display as "----" on the User
Interface or as QNAN in the Modbus registers.

WARNING
CT terminals are referenced to the meter’s neutral and may be at elevated voltages.
TO AVOID DEATH OR SERIOUS PERSONAL INJURY:
• Do not contact meter terminals while the unit is connected
• Do not connect or short other circuits to the CT terminals
For all Series 4100 meters, CTs are polarity sensitive.
Observe orientation.

Fuse Recommendations:
Page 10
Keep the fuses close to the power source (obey local and national code requirements).
For selecting fuses and circuit breakers, use the following criteria:
• Select current interrupt capacity based on the installation category and fault current
capability.
• Select over-current protection with a time delay.
• Use a voltage rating sufficient for the input voltage applied.
• Provide over-current protection and disconnecting means to protect the wiring. For
DC installations, provide external circuit protection. Suggested: 0.5 A, time delay
fuses rated for DC operation at or above the supply voltage.
• Use the earth connection (G) for electromagnetic compatibility (EMC), not a
protective earth ground.
