General Information
Primarily the 6700 Series converts the 120 volt AC power into filtered DC to operate all 12 volt operated lights, fans, TV, water pump, etc. with or without a battery connected.
All 6700 models contain an automatic battery charger that will charge your RV battery (if installed) while the RV is plugged into shore power.
In addition to converting 120 volt AC to 12 volt DC the converter contains the vehicles 120 AC breakers that protect the AC appliances and outlets.
All user functions (resetting circuit breakers or replacing 12 volt DC fuses) are accessed by grasping the upper area of both sides of the plastic door and pulling out and down.
Operation
The power converter operates only when the RV is plugged into a 120 volt AC power. All 6700 Series converters are rated for use with a standard 30 amp 120 volt RV type shore-line cord.
The 6700 series also employs over temperature protection, if the unit is loaded beyond the nameplate rating or the ventilation slots are obstructed, the converter will shut off then automatically turn back on when it has cooled down.
To operate 120 DC appliances from the converter simply plug in the shoreline cord from the RV to 120 volt 30 amp supply. If the converter does not come on check to see if the 120 volt breakers on the front panel are switched on.
Operation From Battery Power
When the shore-line cord is unplugged or the converter AC breaker is off the 12 volt system will automatically operate from the RV battery.
NOTE: If a battery is not connected, the 12 volt system will only work when the converter is plugged into shore-line power.
Automatic Battery Charger
The 6700 Series charger is fully automatic and regulated. This means it always monitors battery condition and sends the correct amount of current needed to recharge and maintain the battery.
Batteries gas as they are discharged and charged causing the fluid level in the battery to evaporate. If the fluid level drops below the plates in the battery, exposing them to air, the performance will be greatly reduced eventually causing the need for battery replacement.
Always follow the battery manufacturers routine maintenance instructions. NOTE: Sealed or maintenance free batteries do not require fluid level checks.
During long periods of non-use MagnaTek recommends plugging in the RV shore-line once a month to maintain the battery.
The full nameplate DC current rating of the converter is available for battery charging. If your battery is discharged the converter may exceed the maximum current rating during the recharge period. If this occurs the converter will automatically reduce its output voltage to protect its self. Under certain conditions the converter may exceed the maximum temperature allowed and shut off for a brief period then return to the task or recharging the battery.
This condition should be of no concern. This is called cycling and will continue until the recharge load drops below the nameplate rating. To help the recharge process reduce the 12 volt loads (lights, motors etc.) As much as possible.
NOTE: During battery replacement observer battery polarity. If the battery polarity is reversed the battery fuse will blow on the front panel of the converter. When any fuse is replaced always replace with same fuse rating as marked on front panel.
Optional Battery Charger Timer. Option (T)
The optional battery charger timer system allows a higher battery recharge voltage for fast recharge of the battery. After 14 hours of recharge the timer instructs the converter to lower the voltage to prevent over charge. This system in especially valuable in long term hot weather environments to prevent over charge.
120 Volt AC Power Distribution Section
All 6700 series converters contain the 120 volt AC breakers that protect AC appliances. This includes but is not limited to AC receptacles, power converter and roof air conditioners.
If a breaker trips because of an overload, reset it by shutting the breaker off (moving the handle down), then turning the breaker back on by moving the handle up.
NOTE: If the breaker trips again, help from a qualified electrician or RV technician should be contacted to fix the problem.
DC Fuses
Fuseholders for replaceable automotive type fuses are located on the upper right hand corner of the faceplate. Maximum fuse size and circuit identification are provided to the left of the fuse holders. To maintain safe and correct operation use only Little-fuse type 257 fuse.
