When connected to 240 Volt AC/50 Amp service or generator service, the Energy Management
features of the unit are disabled and the unit switches all controlled loads "ON". It will not shed
loads. If in either of these modes the load usage should require more than is present, you will
trip the supply line breaker. If connected to a 240 Volt AC/50 Amp, a signal is sent to the
display causing the load meter to go blank, the 50 Amp service indicator to light, and all power
status indicators to light. If the Generator is running, the energy management feature is disabled
and a signal is sent to the display causing the load meter to display actual load current, the GEN
SET service indicator to light, and all power status indicators to light.
NOTE: There is a two minute minimum delay period after a load is shed before the load will be
turned back on again. This is to prevent the air conditioners from turning on with a head of
pressure.
A 12 Volt DC Fuse Panel is located next to the 120 Volt Breaker Panel. The panel contains
circuits with replaceable fuses for protection of the motorhome’s 12 Volt lines. If any line is
loaded beyond the capacity of its fuse, the fuse will “blow”. A portion of the 12 Volt load on the
line must be turned off to reduce the total load on the line to a level below the capacity of the
fuse. Replace the fuse with the same size fuse. DO NOT replace with a larger fuse than
indicated.
If the reduction of load on the line does not stop “blowing” the fuse, there may be a “short”
somewhere along the 12 Volt line or at a non-fused 12 Volt component on the line. Check the
12 Volt line and any components along the line. Locate the “short” and take necessary steps to
repair it. If you cannot locate the problem, have a qualified electrician check it out.
It is a good idea to keep additional fuses on hand in the motorhome. Replacement fuses are
available at most service stations, hardware and automotive supply stores. Remember that the
replacement fuse must be the same amperage rating as the original.
Located at the foot of the bed are the 120 Volt Breaker Panel and the 12 Volt Fuse Panel.
Each panel has its own label for identification and are shown on the next pages for reference.
NOTE: Options selected for your motorhome will determine the type of 12 Volt Breaker Panel.
The sequence of labels may vary from the diagram and your 120 Volt Breaker Panel.
