Description
The deeper vented tops (500- through 800-mm deep) have integral fan trays with cutouts for mounting additional fans (see Additional Fans table). Accessory fan kits (consisting of three pre-wired fans) can be installed to provide additional airflow. Unused fan positions are provided with covers to prevent short-circuiting of airflow. Since the fan pulls air through the enclosure to cool equipment, an optional Inlet Vent (catalog number PPV32 or PPV32B) must be ordered separately. Vented tops are 16-gauge steel and finished with RAL 7035 light-gray textured polyester powder paint. EMC tops are finished with paint over plated 16-gauge surfaces. The vented top is designed to be used in place of a standard top. Bolts are provided to secure vented top to frame. The enclosure can be lifted with a vented top installed (requires accessory lifting eyes).
