Conduit Sealing
All conduit entrances must be sealed with conduit foam. Ensure to use a product that is listed for use in
electrical applications. Polywater ® ATF
TM
Spray Foam Sealant is an excellent option. Follow the
manufacturer’s recommendations when sealing conduit entrances.
WARNING
Condensation and Water Ingress Will Cause Damage:
The Solectria
XGI 1500 inverter has a NEMA 4X, Type 3R, IEC IP66 enclosure. If not
properly installed, or if not properly maintained during extended periods of
sitting idle (non-operating), all NEMA 4X, Type 3R, IEC IP66 enclosures are
susceptible to water ingress and condensation that will damage critical
components.
IMPORTANT:
After sealing the conduit entrances, the risk of condensation increases when the XGI 1500
inverters are inoperative for an extended period of time. Inverters often sit idle for an extended period
between the initial installation and the commencement of normal, autonomous daily operation. Follow these
guidelines:
Manage Moisture During Extended Down-Time (non-operating inverter for more than 1 week)
•
Extended periods of down-time can occur, for example, if turn-on/start-up is delayed more than one
week following initial installation, or if the inverter is idle for more than a week during a service event.
For any reason, if an inverter will be idle for longer than one week, install a desiccant pack inside the
inverter. See Fig. 3-17 below for placement and orientation of the desiccant pack inside the inverter.
•
For long idle periods, visit the inverter at least once per month to inspect the desiccant, remove all
moisture inside the inverter, and replace the desiccant pack as necessary.
•
Before turn-on/start-up following a period of down-time, inspect the inverter, remove all moisture
inside the inverter, and remove the desiccant pack and any debris.
•
Desiccant packs are only intended to protect the inverter from moisture during periods of down-time,
and
should not be left inside an operating inverter
.

WATER INGRESS WILL VOID WARRANTY:
It is the responsibility of the installer to maintain a dry,
moisture-free inverter enclosure; water ingress is not covered under warranty.
