WARNING: Shock Hazard

During an error shutdown, the inverter's output terminals are not live. However, if

the inverter recovers from a shutdown, the terminals will become live without notice.

Several error shutdowns can be recovered automatically, including Low Battery V,

High Battery V, and Over Temperature. See page 51.

NOTE:

In Table 5, "System display only" usually indicates that a MATE3-class device is

required to perform the step. It cannot be performed without the system display.

Possible Remedy

Use a DC voltmeter to check the voltage directly on the DC

terminals. If not present, the problem is external. If present,

the inverter could be damaged.

See the Installation Manual for the location of J3. Confirm the

jumper is present. If missing, replace the jumper. Or follow

the manual instructions to install an external switch.

The Radian inverter is given an initial

factory. With DC present, use narrow pliers to remove jumper

J3 from its pins. Once removed, install it again. This is the

equivalent of "jiggling the switch."

System display only: Set to On with the INVERTER hot key.

NOTE : The O

System display only: If constant power is required, set to On

with the INVERTER hot key. (If this setting was intentional,

then no action is required.)
