Installation Guidelines
-
Power Status: Always ensure the main power source is disconnected before inserting or removing the module from the chassis.
-
Mounting: Ensure the module is fully seated in the designated power supply slot of the TI500 chassis to guarantee proper backplane contact.
-
Environment: Maintain adequate clearance around the module to facilitate airflow and heat dissipation, keeping ambient temperatures within the specified 0 to 60 deg C range.
-
Grounding: Use appropriate grounding practices to ensure the chassis is effectively bonded to the facility ground bus to prevent electrical noise coupling.
-
Handling: Observe standard ESD (Electrostatic Discharge) precautions when handling the module to prevent damage to sensitive internal circuitry.
FAQ
