Features
High/Low Voltage Protection
Whenever AC power falls below 104 volts, or rises above 132 volts, the EMS automatically shuts down power to the RV. The EMS will monitor the power and once
the AC power rises above104 volts, or drops below the 132 volt level, the time delay indicator flashes for the preset time and then automatically restores power to the RV.
Time Delay for A/C Compressor
If AC power is interrupted, or the EMSdetects a fault condition, the built in time delay is activated. There is a 136-second (02:16) time delay.
3-Mode Surge Protection
This feature provides full surge protection L-N, L-G, and N-G. Total Joule rating is 1790, 44,000A Surge Current. Response time of <1 nano second.
Surge Indicator
In the event of a power surge and the surge protector circuit is damaged within the EMS, L-N, or L-G, the digital display error code will read E-10. This indicates the EMS needs to be serviced.
Reverse Polarity Protection
If AC power is a reverse polarity condition, the EMS will not allow power to the RV and the error code will read E1.
Open Neutral Protection
If AC power has an open neutral condition, the display will not light, and the EMS will not allow power to the RV.
Open Ground Protection
If AC power has an open ground condition, the EMS will read an error code of E2, and will not allow power to the RV.
AC Frequency Protection
If AC power frequency deviates plus/minus 9 hertz from 60 cycles per second, the EMS will shut downAC power. An Error Code of E7 will be displayed when the frequency is high; and an Error Code of E8 will be displayed when frequency is low.
Accidental 240V Protection
If 240 volts is detected when plugging intoAC power, the EMS willNOT allow power to the RV. If this condition occurs while power is applied to the RV, the EMS shuts off power instantly. The display will read the voltage and-3 Efor the error.
(NEVER BYPASS THE EMS WHEN THIS OCCURS.)
Display
Continuously scrolls all of the AC power information, including voltage, current, frequency, error codes, and previous errors.Each reading is displayed for two (2) seconds.
Previous Error Code
This feature tells the user what het previous error was and why power was interrupted to the RV. To read a Previous Error Code, put a “P” in front of the “E” code. This is
only displayed if an actual error occurs. The error is deleted when the power is disconnected from the EMS.
Weather Resistant
Can be exposed to elements, however, may not be submerged.
Microprocessor controlled
The computer is driven by a state-of-the-art microprocessor that is programmed with software to drive the entire EMS.
Built-in Lock Bracket
Allows the user to secure the EMS to power source to prevent theft.
Warnings
•Do not exceed the rating on the EMS for any reason, however these devices are designed to be reduced down to 120V/15A, and still maintain full protection.
• Do not modify the EMS in any way, this will void th warranty, compromise protection, and could result in possible shock, and/or a fire hazard.
•It is important to always check the pedestal power outlet for
charring; this condition means that ACthe receptacle is providing a weak connection.DO NOT USE! It could result in possible melting of the RV power plug.
•When running extension cords from the RV ACto power,
always use a 10-gauge cable for your 120 volt, 30 Amp system. Make sure that the cable is rated for outdoor use to reduce the risk of electric shock. Small gauge cable will have a higher resistance and will result in voltage loss, plus it may result in an electrical fire.
•Whenever servicing or installing the EMS, or any other AC powered device, make sure AC power is disconnected.
•RV wiring is different than the wiring found in homes; the neutral and ground conductors are isolated in the RV, unlike in
a home where they are tied together at the service panel. The reason is: homes have a bonded ground system, whereas RV’s do not. Therefore, never bond the neutral and ground together for any reason. This will create a ground fault condition, and may result in electric shock and/or a fire hazard.
•Never plug the EMS into an inverter.
