and void the warranty. Remember that
incoming AC must be fed only to the AC input
and never the AC output. Always check for AC
voltage before connecting wires to the AC
output. Do NOT turn the inverter ON until all
AC connections have been made. Back-
feeding the inverter voids the warranty.

Do not connect incoming AC from any
source to the AC output of the inverter.
This is known as back-feeding and will
damage the unit and void the warranty.

occur if the unit's AC output is connected to
the entire leg of a circuit breaker panel, then a
circuit breaker on that leg is used to feed the
battery charger input. This will cause the unit
to oscillate ON and OFF when the unit is in
inverter mode.

nections to meet all requirements, T&B recom-
mends that each terminal be crimped in two
places with a pressure of 15 tons using a hex-
agonal die. The T&B die has a code
number of 54. After the crimp is made, the
barrel of the terminal and the first inch of the
cable needs to be covered in UL Listed or UL
Recognized heat shrink tubing. Heart Interface
recommends a 2-inch length of 3M HDT 0800
tubing. Other heat shrink may be used if it is
UL Listed or UL Recognized as long as the
manufacturer' s directions are followed.
