DELTA Amplon RT 5 Rack Mount UPS
Product Introduction
The Delta External Charger Box works as an external charger for a 5~20kVA on-line UPS. Its output power factor reaches to 0.97 and efficiency is up to 90%. The charger box provides wide range of charge voltage (120Vdc to 290Vdc) for you to adjust according to battery capacity. Working with a UPS, the charger box can charge lead-acid batteries and lithium batteries. Through the provided RJ45 cable, the charger box can send alarm signals to the UPS, which enhances the UPS’s monitor function.

Important Safety Instructions
Please read this user manual before operation and keep it for later reference. Failure to heed the manual will void the warranty.
- Install the charger box in a well-ventilated area. Do not expose it to rain, dust, and moisture. Keep it away from flammable gas or explosives.
- To protect the charger box from overheating and to ensure its reliability, do not block or cover its slits and openings.
- Do not put beverages on the charger box.
- All maintenance services must be performed by qualified personnel. Do not open or remove the cover of the charger box to avoid high voltage electric shock.
- The charger box must be well grounded due to a possible risk of current leakage.
- There is a risk of dangerous high voltage when the batteries are still connected to the charger box. Before maintenance of the charger box, do not forget to remove the input power cord and disconnect the battery cable to completely cut off the power source.

Installation and Configuration
Installation
Rack Mounting:
- Attach the included bracket ears to the lateral mounting holes of the Delta external charger box. See Figure 4.
(Figure 4: Mount the Bracket Ears)
- Follow steps 1 to 2 to install the Delta External Charger Box in Delta’s rail kit (optional). See Figure 5.

Maintenance
Charger Box Cleaning:
- Regularly clean the charger box, especially the slits and openings, to make sure air flows freely through the charger box to avoid overheating.
Charger Box Inspection:
- Regularly check the charger box and inspect:
1. Whether the LED indicators are normal.
2. Whether the fan works normally and air flows freely through the charger box.
Fan:
- Higher temperatures shorten fan life. When the charger box is running, please check if the fan works normally and make sure the charger box is ventilated properly. If not, replace the fan.
NOTE:
Please ask your local dealer or customer service representative for more maintenance information. Do not perform maintenance if you are not trained for it.
