enclosure has five metal walls, leaving the bottom of the unit fully exposed. It must be mounted to a
metal bulkhead panel such that the panel covers the exposed bottom side.
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 easy installation/maintenance.
The standard Cell Interface, Bulkhead weighs approximately 450 g.
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.

Optional DIN rail mounting Kit
For applications requiring DIN rail mounting, the Cell Interface may be ordered with the Cell Interface
Mounting Bracket (Bulkhead-to-DIN) kit. This kit is sold separately, and includes a metal plate and
the necessary hardware to securely mount the standard Cell Interface module to EN50022-compliant
DIN rails, as shown in
.
