Ready-to-t solutions
To ensure on-site installation is as straightforward as
possible Weidmüller offers ready-to-t solutions to protect
the DC and AC sides of inverters. Plug-and-play PV boxes
reduce the installation time. Weidmüller will also perform
customer-specic assemblies at your request. More
information is available at www.weidmueller.com
Note:
Country-specic standards and guidelines must be
observed
