WARNING: Shock Hazard and Equipment Damage
It may be necessary to remove the ribbon cables in the course of servicing the Radian. (This
is detailed in the Radian service manual.) The cables must never be removed until all power
has been disconnected for a minimum of one minute. If the cables are removed prematurely,
the Radian’s capacitors will retain a sizable charge, which can cause electrical shock or
severe equipment damage during normal handling. This damage is not covered under the
unit’s warranty.
12V AUX: Delivers 12 Vdc up to
0.7 amps (8.4 watts). The output can
be switched on and off for many
functions. See page 33 for details.
SWITCH INV eceives wires for a
manual on/off switch to control the
inverter. See page 32 for instructions.
NOTE: The ON/OFF INV jumper (J3)
overrides these terminals when installed.
(See above.)
RELAY AUX: Relay contacts with
no voltage (10 amps at 250 Vac or
30 Vdc). The relay can be switched
on and off for many functions. See
page 33 for details.
ON/OFF INV JUMPER (J3): Overrides the
SWITCH INV terminals when installed. When
installed, the inverter is On. The On or Off states
can then only be controlled by the system display.
NOTE: J3 is installed to the ON position during
manufacture, but the Radian inverter is given an
external OFF command at the same time. Its
initial state will be Off.
DC TERMINALS Connects to the battery cables and DC system.
There are two DC positive and two DC negative terminals. Each DC
positive terminal requires separate cables and separate overcurrent
protection. See page 26 for instructions.
RIBBON CABLES Connects the Radian’s power
modules and control board. See Warning below.
