Fronius DC Box 60/12 (open)
The Fronius DC Box 60/12 is designed for use with the following inverters:

Inverter

These inverters have integrated overvoltage protection on the DC input
side.
For this reason, no overvoltage limiter is required in the Fronius DC Box
60/12.If type 1 or type 2 overvoltage protection is desired, it can be in-
stalled in the Fronius DC Box 60/12 on the DIN rail provided for this purpo-
se.
Important! With operation of the DC Box 60/12 in conjunction with the
inverters Fronius IG 15, 20, 30, 40 and Fronius IG 60 HV, there is no DC
disconnect in the photovoltaic system. If required, provide a suitable DC
disconnect.

Fronius IG 60 HV
Fronius IG Plus
Fronius IG Plus V
Fronius IG TL
NOTE! Other inverters that do not have integrated overvoltage
protection on the DC input side cannot be used without due con-
sideration.
The Fronius DC Box 60/12 is desig-
ned for use in grid-connected pho-
tovoltaic systems with several solar
module strings.
Six to twelve solar module strings
can be integrated at the input of the
Fronius DC Box 60/12 to reduce
these at the output to one DC+ and
one DC- main line.
