Integration note for the panel
This sinus filter mounts inside an Altivar floor-standing enclosure with separate air flows, or the compact version. It's not a standalone panel-mount device — the enclosure integration is assumed. Verify gland-plate clearance and thermal derating if the enclosure is already at fill-factor limits.
