the back of the unit fully exposed. It is designed to mount to a metal bulkhead panel such that the
panel covers the exposed back.
The Cell Interface is rated to operate in the temperature range of -10 °C to 60 °C. It is designed for
indoor use.
The Cell Interface should be mounted against a flat surface with the 'Link In' and 'Link Out' ports
pointing up to the sky.
Ensure the enclosure is connected securely to Earth, either by grounding the
mounting surface or by using a dedicated Earth Bonding Conductor.
4.3.2.1. Mounting Clearances
The NUV100-CI-12-1 and NUV100-CI-16-1 variants produce up to 24 W and 32 W, respectively,
during cell balancing. A portion of this heat is transferred to the bulkhead.
Extra space should be provided around the module to allow for sufficient heat dissipation as well as
easy installation and maintenance.
If mounting a Cell Interface, PCB assembly only (no enclosure), note that the Cell Interface contains
high-voltage signals reaching as high as 1250 V DC. Care must be taken when mounting the PCB into
a metal enclosure to ensure that the metal walls remain a safe distance from the exposed conductor
on the PCB. Using 1250 V DC as an example, the metal walls of the enclosure must be at least 4.2
mm from the nearest exposed conductor and must not touch the PCB or any component on the PCB,
including the connector housings.
4.3.3. Mounting Instructions
Ensure appropriate fasteners (not included) are used to mount the Cell Interface. These fasteners will
vary depending on the material and construction of the mounting surface.
It is suggested to use #8-32 screws with a split lock washer for the mounting holes provided on each
side flange of the Cell Interface.
