4.2 Mounting the I/O Box
Damage to the products and cables due to moisture
The Inverter Manager and the I/O Box are not protected
against splash water. Consequently, moisture can
penetrate the device and damage the products and
cables.
• The Inverter Manager and the I/O Box must be
installed in a dry environment, e.g. indoors or in a
splash-proof enclosure (degree of protection: at least
IP54 (NEMA 3R)).
