F50-ATS
50amp 125/250V Automatic Transfer Switch
Furrions ATS is used to safely switch automatically between mutiple power sources
Furrion’s 50amp Automatic Transfer Switch with built in safe switch interlock system
is used to automatically switch between two separate 120/240 volt AC power sources,
these power sources can be from a Generator, shore power cord or inverter.
The function of the Furrion Automatic Transfer Switch is to provide a safe and smooth
switch over from an inverter or shore power cord automatically when a generator is
started and brought online, the Furrion ATS oers the added feature of a mechanical
interlock between contactors to ensure both contactors cannot be closed in parallel
which could otherwise create an over voltage situation on the output line.
The electrical contacts in the transfer switch are normally in the open position, once
AC voltage is applied to input 1 this will automatically close the contacts in contactor 1
and feeds the output line from the shore power cord or inverter.
Once AC power from the Generator is sensed by the transfer switch at Input 2 terminals,
this will start a timer and automatically switch over to generator power supply after a
20-30 second delay which ensures the generator has sucient time to run up to speed
before electrical load is applied.
PLEASE READ ALL SAFETY INSTRUCTIONS BEFORE INSTALLING THIS TRANSFER SWITCH!
WHEN PROTECTED BY A MOLDED CASE CIRCUIT BREAKER RATED TO 50AMPS OR LESS,
THIS LINE/GENERATOR SWITCH IS RATED TO 5000 SYMMETRICAL AMPS.
BEFORE PREFORMING MAINTENANCE OR INSTALLATION PLEASE ENSURE TO ISOLATE
ALL POWER SOURCES!
Ensure generator is shut o and auto start feature (if applicable) is isolated.
!
Conrm external power cord is disconnected and stored in an area where it
!
cannot mistakenly be plugged in.
Conrm the inverter (if used) has been disconnected.
!
Conrm with an AC/DC electrical tester that no voltage is present at any of the
!
connections before beginning installation or maintenance.
Label all electrical parts with a warning tag to show work is in progress before
!
beginning work.
Furrion warranties this transfer switch in the Continental Untied States of America
and Canada from defects in materials or workmanship under normal use for 1 year
from date of purchase.
