Description
Enclosure for MVAC250 and MVAC400 product series
PRODUCT OVERVIEW
The MVAC-COVER is intended as an enclosure for the MVAC400 & MVAC250 series of open frame prod-
ucts and can be used with the models shown in the Model Usage Table.
It is intended for system deployments where the product is deployed in a semi open environment and not
mounted in a totally enclosed system case (where the product is inaccessible to End Users).
It is manufactured from high quality steel and provided with an anti-corrosion coating.
The construction also provides an optimized airflow pattern to accommodate both forced and convection
cooling deployments.
The MVAC-COVER kit is sold separately and it is intended that the End User assembles the MVACxxx open
frame product directly.

INSTALLATION INSTRUCTIONS
1. Install the insulator (➂) in to the chassis base (➀) taking care to align the “cutout” with the “grounding
symbol” (clearly stamped in the chassis) and PEM standoffs and ensuring that the insulator lies flat against
the chassis base when properly installed.
2. Lower the MVAC-400 into place with the orientation as shown in the above diagram.
3. The mounting holes (slotted holes) should align with the 4 PEM standoffs provided in the chassis base.
4. Install the M3 x 6 pan head screws (➃) complete with cup washers.
5. Align the cover with the chassis base (➀).
6. Secure cover (➁) to the chassis base with the 4 M3 x 6 countersink screws (➄).
7. Inspect the completed assembly for misalignment (cover, chassis base, insulator, or PCB).
