Invensys RF Load Control Meter
General Instructions
Description
The Invensys RF Load Control Meter (LCM) is a
remote switching device that receives load control
OFF and ON commands from the GoodWatts
system. Commands are received via an RF
Communications network.
The LCM is connected in line with the existing
electrical wiring to the appliance, which enables it to
be mounted at any location with easy access to the
existing wiring. The enclosure is watertight, dust
tight, and corrosion resistant, making it suitable for
both indoor and outdoor locations. Mounting holes
are provided at each corner to secure the LCM to a
flat surface.

Note: This equipment has been tested and found to
comply with the limits for a Class B digital device,
pursuant to Part 15 of the FCC Rules. These limits are
designed to provide reasonable protection against
harmful interference in a residential installation. This
equipment generates, uses and can radiate radio
frequency energy and, if not installed and used in
accordance with the instructions, may cause harmful
interference to radio communications. However, there is
no guarantee that interference will not occur in a
particular installation. If this equipment does cause
harmful interference to radio or television reception,
which can be determined by turning the equipment off
and on, the user is encouraged to try to correct the
interference by one or more of the following measures:
– Reorient or relocate the receiving antenna.
– Increase the separation between the equipment and
receiver.
– Connect the equipment into an outlet on a circuit
different from that to which the receiver is
connected.
– Consult the dealer or an experienced radio/TV
technician for help.

Installation
Caution: This equipment is authorized for use under the United States Federal
Communication Commission Rules and Regulations, Code of Federal Regulations
Chapter 47 part 15 and must be installed in accordance with the instructions provided in
this document. In accordance with FCC requirements, changes or modifications to this
equipment that are not expressly approved by the party responsible for FCC compliance
could void the user's authority to operate this equipment.
Inspection
Inspect the carton for damage. If damaged, notify carrier immediately. Inspect
LCM for damage. Return damaged products.
Requirements
– Installer must be a qualified, experienced technician.
– Job wiring diagrams
–Tools
•Drill bits for panel mounting holes
•Static protection wrist strap
–Mounting screws (4)
General Precautions
Warning: Electrical shock hazard! High voltage is present in the Load Control Meter.
Turn OFF electrical power to the LCM and the electrical appliance prior to installation
or service. Failure to turn off power may result in serious personal injury.
– Follow Static Precautions when installing this equipment.
– Use suitable copper conductors.
– Make all connections according to electrical wiring diagram, national and local
electrical codes.
Static Precautions
Static charges damage electronic components. The microprocessor and
associated circuitry are sensitive to static discharge. Use the following
precautions when installing, servicing, or operating the system.
– Work in a static free area
– Discharge static electricity by touching a known, securely grounded object.
Location
The LCM is connected in line with the existing electrical wiring to the appliance,
which enables it to be mounted at any location with easy access to the existing
wiring. The enclosure is watertight, dust tight, and corrosion resistant, making it
suitable for both indoor and outdoor locations.
– Avoid mounting locations where excessive moisture, corrosive fumes, vibration, or
explosive vapors are present.
– Avoid electrical noise interference. Do not install near large contactors, electrical
machinery, or welding equipment.
– Locate where ambient temperatures do not exceed 150 deg. F (65 deg. C) or fall
below -40 deg. F (-40 deg. C).

Mounting
Mounting holes are provided at each corner to secure the LCM to a flat surface. Figure 4
shows mounting dimensions. Refer to FIGURE 9. Mounting Template, on page 8 for an
installation template at actual size.
FIGURE 2. Enclosure dimensions
1. Select a flat mounting location.
2. Mark and prepare the surface mounting holes, using dimensions above or use the
template in FIGURE 9. Mounting Template, on page 8.
3. Remove the cover from the LCM enclosure by removing the four cover attaching
screws in the corners of the cover.
4. Insert mounting screws down through the same holes that the cover screws came
out of and securely fasten the LCM enclosure to the flat surface.

6. After wiring is complete, replace the cover and tighten it securely with the four cover
screws.
7. Reapply power to the LCM and the electrical appliance.
Wiring
Caution: It is important to select cable that complies with the NEC code for the
electrical appliance being wired.
The EMSL-100 can control 120 VAC single-phase loads with current ratings up to 30A
resistive. The EMSL-200 can control 240 VAC single-phase loads with current ratings up
to 30A resistive. The LCM is connected in-line with the existing electrical wiring to the
appliance. Multiple-size knockouts are provided around the exterior perimeter of the
housing to accommodate a conduit connector or a cable clamp. Refer to the wiring
chart in Table 3 for terminal listings for both LCM models. Refer also to the example
wiring diagrams in Figure 5 through Figure 8.
Warning: You must turn off AC power to the electrical appliance that you are wiring.
Failure to turn off power could result in physical injury or death.
1. Shut off AC power to the electrical appliance being wired.
Caution: Use only NEMA 4x rated fittings in order to maintain the NEMA 4x rating.
2. Connect the wires for the input (from the AC source) and output (to the electrical
appliance) as shown in Table 3 and in Figure 4. Refer to Figure 4 to see typical wiring
for a 120 VAC and a 240 VAC system.
