Safety Precautions
NOTE: The proper crimp tool and die must be matched by the connector
type.
7.1.3 Distance Requirements
Table 7-1 shows the distances between Fusion components and related equipment.
7.2 Safety Precautions
7.2.1 Installation Guidelines
Use the following guidelines when installing TE equipment:
1. Provide sufficient airflow and cooling to the equipment to prevent heat build-up
from exceeding the maximum ambient air temperature specification. Do not com-
promise the amount of airflow required for safe operation of the equipment.
2. If you are removing the system, turn it off and remove the power cord first. There
are no user-serviceable parts inside the components.
