Before installation and usage, please read this User Manual thoroughly. This helps you to
use the product correctly and safely.
Install the PDB in a well-ventilated area, away from excess moisture, heat, dust, flammable
gas or explosives.
To avoid fire accidents and electric shock, please install the PDB in an indoor area free of
conductive contaminants and the temperature and humidity must be well-controlled. For the
temperature and humidity specifications, please refer to Appendix 1: Technical
Specifications.
Leave adequate space (at least 50 cm (1.97”)) at the front and rear of the PDB for proper
ventilation.
Connection Warnings
The PDB must be well grounded due to a possible risk of current leakage.
The installation of upstream and downstream protection devices is highly recommended
when the PDB is connected to the UPS.
The protection devices connected to the PDB must be installed near the PDB and must be
easily accessible for operation.
If you need to move the PDB or perform re-wiring, please turn off the AC input power.
Otherwise, the output end might still be energized, which might cause electric shock.
Usage Warnings
To ensure reliable operation of the PDB and to protect the PDB from overheating, the slits
and openings in the PDB must not be blocked or covered.
Before usage, you must allow the PDB to adjust to room temperature for at least one hour to
avoid moisture condensing inside the PDB.
Do not pour and splash any liquid on the PDB. Do not insert any object into the PDB’s slits
and openings. Do not put beverages on or around the PDB.
