INSTRUCTION MANUAL:
ELECTRICAL MANAGEMENT SYSTEM (EMS)
surge protection module is depleted and is no longer providing surge protection to
your RV. It is recommended that you replace the surge protector. This error will not
shut off incoming power to the RV.
•
Reverse Polarity Protection: Reverse polarity is a condition where the hot line and
the neutral line are reversed. A reverse polarity condition could harm you and/or
your RV electrical system and electrical equipment. If the EMS unit detects a reverse
polarity condition, the EMS will not provide power to the RV and a reverse polarity
error code of
E 1
will be displayed.
•
Open Neutral Protection: Open neutral is a condition where the neutral wire is
disconnected and could pose a shock hazard. An open neutral condition could harm
you and/or your RV electrical system and electrical equipment. If an open neutral
condition is present, the EMS will not turn on. Since the EMS is off, the display will
not illuminate and power to the RV will not be activated.
•
Open Ground Protection: Open ground is a condition where the earth ground
wire is open or the neutral and ground wires are not bonded together creating an
electrical safety hazard. An open ground condition could harm you and/or your RV
electrical system and electrical equipment. If the EMS unit detects an open ground
condition, power to the RV will not be provided. The open ground error code shown
on the display will be
E 2
.
•
AC Frequency Protection: The normal operating frequency of the AC voltage
should be 60 Hertz. AC frequency below 51 Hertz or above 69 Hertz could harm
your RV electrical system and electrical equipment. If the frequency is outside the
stated ranges, the EMS will shut down power to the RV. An error code of
E 7
will be
displayed if the frequency is high. If the frequency is low, the display will show an
error code of
E 8
.
•
Accidental 240V Protection: If 240 volts is detected when plugging into AC
power the EMS will NOT allow power to the RV. Should this condition occurs while
power is applied to the RV, the EMS will shut down power instantly. The EMS will
indicate an E 3 error code and display the voltage. (SHOULD THIS OCCUR NEVER
BYPASS THE EMS).
•
Display: Display continuously updates, at 2 second intervals, all AC power
information: voltage(s), current(s), frequency, error code, previous error code
(if applicable).
•
Previous Error Code: Previous error code (PE) indicates what error occurred and
why power was interrupted. To delete code, disconnect power from EMS.
•
Weather Resistant: Unit can be exposed to outside weather elements; however,
the unit may not be submerged. Unit is designed to be mounted or used vertically.
•
Built-in Locking Bracket: Helps prevent theft by securing the EMS to the power
source pedestal using a lock, such as a bicycle cable lock.
NOTE: Provided you have the proper adapter, the EMS may be used with 15A, 20A, 30A
or 50A service and will provide full protection. The power should be limited to the lower
amperage rating of the power source and RV. The circuit protection at the power source and
the RV are the current limiting devices.
