1) Panel Preparation and Installation
a. Remove cover and set aside.
b. Review mounting site and determine the best position for mounting the emp.2 panel.
c. The panel should be mounted as close to the circuit wiring being monitored as possible.
d. The panel is to be mounted high enough so that the conduit entrance (Figure 1A) is via the bottom
ONLY.
e. Access shall be via two (2) or less, 1 inch (2.54cm) conduits (Figure 1A).
f. Do not remove the interior electronics and PCB.
g. Conduits to enter via the bottom of the cabinets only and be located no less than 1.5 inches
(3.81cm), center line from the back of the cabinet. Use a piece of cardboard or wood to protect
the internal electronics when drilling into the panel for the conduit entry.
h. Preferred method is seal tight flexible conduit and appropriate connectors and supports.
i. Four mounting brackets (Figure 1B) are located on the back side of the cabinet and are to be used
for mounting. DO NOT DRILL back of the cabinet.
2) Interior Wiring for the Monitoring and Control
Panel
emp.2 Power Source
a. The emp.2 is designed for residential energy monitoring.
b. The power source for the emp.2 is 240 volts' single phase
and is accessed by the host power panel being
monitored.
c. The circuit shall be a 15 amp two pole circuit breaker and
terminated on the terminal block (Figure 1C and Figure
3H) at the lower left hand corner of the monitoring
control panel labeled "L1 – N – L2".

- Page 2 CT Termination at emp.2 d. CT 1 and 2 terminals (Figure 1D) are set aside for total panel kW monitoring. The CT itself will be attached to the incoming L1 and L2 in the power panel. “L1” terminated on CT terminal #1 (CT1‐ L1). “L2” terminated on CT terminal #2 (CT2‐L2). Care should be taken when setting these two CTs to preserve polarity. The arrow on the CT side label should point in the direction of the panel and circuit breakers. e. CT 3 and 4 terminals (Figure 1E) are pre‐designated for “Solar” monitoring if PV cells have been installed. Incoming power from the solar inverter will be monitored at the solar circuit breaker or disconnect. “L1” terminated on CT terminal #3 (CT3‐L1). “L2” terminated on CT terminal #4 (CT4‐L2). f. CT’s 5 thru 8 terminals (Figure 3I) are for miscellaneous loads within the residence, i.e. A/C units, electric water heater, swimming pool pump, electric range, oven, etc. These appliances are typically 240 volts, but large 120 volt loads may also be monitored. g. All appliances monitored on CT5 thru CT8 will be monitored utilizing “L1” phase only, the load phase “L2” will not have a CT. h. It is essential that CT leads can be “tracked” from the emp panel to the circuit panel for trouble shooting. Therefore, all CT leads should be labeled (Figure 1F) with the appropriate CT number every two feet and care should be taken to land each CT lead at the correct terminal block. i. The CT has two wires, one black and one white (Figure 3J). The black wire will always be ...
- Page 3 Terminal connectors will have to be crimped onto the wiring to connect to the terminals on the relays. The “outside” terminal on the relay should be used and the “middle” terminal is left blank. Phone: 602-606-7652 5235 South 39 Street e-Mail: sales@akida.com Phoenix, AZ 85040 www.akida.com...
