An inv e rter ta ke s dir ect current ( DC ) from you r ba tterie s a nd turns it in to a lte r­nating current ( AC) , exa ctly like you us e a t hom e. I t als o ta kes alterna ting current
when your motor coach is con nected to shor e power and tr ansfor ms it into dir ect
cur rent to re char ge your ba tterie s.

There are two m odes of ope ra tion as socia te d with an inv er ter / cha rger:

I nv er ter Mode :

Dir ec t current (DC ) fr om th e vehicle ’s ba tte ries is transfor med in to a lte rn at ing

cur rent ( AC ) for us e with you hous ehold electr ica l appliances .

Cha rger Mode :

Alternating current ( AC) is ta ke n directly from shor e power ( or othe r AC sour ces )

and pas sed directly to your household applia nce s. At the sam e tim e, th e incom ing

AC is als o converte d to DC to recha rge th e vehicle ’s batteries .

The RD S eries inv er ter/charger ca n power a wide ra nge of household a pplia nces
inclu ding sm all motors , ha ir dry er s, clock s a nd othe r ele ctrica l devic es . As with any
applia nce us ing batte ries for powe r, there is a certain length of tim e that it ca n run ­th is is ca lle d “r un tim e.” Ac tual run tim e depe nds on several var iables including the
size a nd the type of applia nce, the type of ba tteries installed in you r recreational
vehicle , as we ll as the ba tte ry ’s ca pa city and age. Other fa ctor s s uch as the batte ry ’s
state of charge and tem pera ture ca n als o affect the length of tim e y our applia nc es
can run.

Appliances such as TV s, VC Rs , ste re os, compute rs , coffe e pots, in ca ndescent
ligh ts and toa ste rs can all be s uccess fully powe re d by your inver ter. Lar ger electr ical
applia nces , however, such as s toves , wa ter he ate rs , etc. , ca n quic kly dr ain your
ba tterie s an d ar e not re com mende d for this applica tion.

All ele ctrica l a pplia nc e s ar e ra te d by the am ount of powe r the y cons ume. The

L oc at in g t h e I nv e rt er

The inverter must be mou nted in a cle an, dr y, ventila ted env ironm ent wh er e th e
am bient te mpe ra tures will not exceed 12 2 º F ( 50 º C) . The loca tion must be fully

th e inverter horizonta lly, vertically or ups ide- dow n. I t mus t be secu re ly fa ste ned to a
shelf, bulk he ad, or other str uctural pa rt.

Allow en ough clea ra nce to a cces s the AC and DC conne ction points a s well as the
inverter’s cont r ols a nd s ta tus indicator. As with any inver ter, it sh ould be loca ted a s
close to the batte ries as poss ible. Longe r ba ttery ca ble runs te nd to loose efficienc y
and re duce the overall perfor mance of an inverter.

L oc at in g D ed ic a te d B a t te rie s ( o ptio na l)

Dedicated batte ries mus t be mounted in a clea n, dry, v entilated envir onm ent
where they are prote cted fr om high a nd low te mpe ra tures . The ba tteries m us t be

To ens ure optim um perfor mance, a ventila ted batte ry enclos ure is recom m ended.
The ba tterie s s hould be loca ted a s clos e as poss ible to the inv er ter. Longer ba ttery
cable ru ns te nd to loose efficie ncy and redu ce the overa ll perfor mance of an inverter.
