3.1 Mounting requirements
This product is meant to be mounted to an EN 50022 top hat rail (such as Weidmuller’s
TS 35 range) inside a PV combiner box fulfilling IEC 61439-2 (or equivalent local
standard) and only accessible to authorized people. The enclosure of the combiner box
shall fulfill IEC 62208 (or equivalent local standard) to ensure protection against direct
contact, indirect contact and spread of fire. The IEC 60529 ingress protection code of
the combiner box shall be at least IP54. The IEC 62262 degree of protection against
external mechanical impacts of the combiner box shall be at least IK09 (this equipment
has an IK07 rating but once mounted inside an IK09 enclosure there is no realistic risk
of damaging it due to external impacts).
Thermal considerations
• This product does not need forced convection (i.e. a fan) to operate reliably.
• The mounting orientation shall ensure that the PCB of the product is vertical
(i.e. perpendicular to the ground plane).
• Around 30 cm of space above and below this equipment should be free of obstacles
that could prevent the natural-convection air flow.
• This product shall not be installed in the close vicinity of powerful heat sources.
• The combiner box design shall guarantee that the air temperature around the PCB
of this equipment is between –20 °C and +70 °C
• Weidmüller’s range of PV combiner boxes is engineered with these considerations
in mind and the designs are validated with IEC/TR 60890 thermal models and/or
multipoint temperature rise tests. Contact your Weidmüller sales representative
for additional information.
