8 Precautions and Preparations
Before using the NJR-T04HD / NJR-R04HD, follow the precautions and instructions below.
8.1 Attaching Rubber feet
First, clean the bottom surface of the NJR-T04HD / NJR-R04HD as needed, and then peal the release papers
from the rubber feet and place them in each of the four corners.
8.2 Installation
Follow the instructions below when installing the NJR-T04HD / NJR-R04HD.
・
Do not place the NJR-T04HD / NJR-R04HD on another device directly. The temperature of its bottom
surface is elevated after it is powered on.
・
Do not block vent holes. To provide adequate ventilation, maintain sufficient clearances around the
NJR-T04HD / NJR-R04HD (30 mm/1.18 inches or more).
・
When placing the NJR-T04HD / NJR-R04HD in an EIA rack-mount unit, use IDK’s RM-44S, RM-44D, or
RM-4442. If you do not use it, prepare ventilating equipment to keep the ambient temperature at 40
degrees C/104 degrees F or less. If inadequately vented, the life of parts may be shortened and
operation may be affected.
