1. Safety and EMC Instructions Please read carefully the following user manual and the safety instructions before installing or operating the unit! 1.1 Installation ★ See installation instructions before connecting to mains power. ★ Condensation may occur if the UPS is moving directly from a cold to a warm environment.
■ Figure 1.1 The Air Flow Diagram ★ This UPS receives power from more than one source- disconnection of AC source and the DC source is required to de- energize this unit before servicing. ★ An additional circuit breaker or fuse with rating 16A and breaking capacity 3kA shall be used between power source and input when installation this unit.
★ Remove the protective panel only after disconnecting the terminal connections. 1.3 Maintenance, servicing and faults ★ The UPS operates with hazardous voltages. Repairs may be carried out only by qualified maintenance personnel. ★ Caution - risk of electric shock. Even after the unit is disconnected from the mains power supply (building wiring socket), components inside the UPS are still connected to the battery which are potentially dangerous.
★ Do not open or destroy batteries. Effluent electrolyte can cause injury to the skin and eyes. It may be toxic. ★ Please replace the fuse only by a fuse of the same type and of the same amperage in order to avoid fire hazards. ★...

(3) Battery Input Connection for long backup time model When connecting the external batteries it’s recommended to pay attention to these following items: ★ Use the battery pack with voltage: 24VDC for 1KL T (2 pcs of 12V batteries), 48VDC for 2KL T, (4 pcs of 12V batteries), 72VDC for 3KL T (6 pcs of 12V batteries) Note: Connection of batteries more than or less than required will cause abnormality or permanent damage.
(4) EPO Connection: EPO (Emergency Power Off) function is standard feature for UPS, the polarity of EPO is configurable; EPO is normally close as default setting. If the connection between two ports of EPO connector is disconnected, EPO function will be active and the UPS will stop output power immediately.
5.4 Turn on the UPS: (1) With mains power connecting: Press On-button continuously for more than 1 second to turn on the UPS, the UPS will get into the Line mode; the LCD screen will indicate the state of the UPS. (2) Without mains power connecting: Even though mains power is not connected to the UPS, the UPS still can be turned on by just simply pressing on button continuously...
5.7 Audible alarm mute function: If the audio alarm is too annoying in battery mode, the audio alarm is able to mute by press ON button continuously for more than 1 second. Moreover, the audio alarm will be active again when the battery reaches low status for reminding that UPS output power will shut down soon.
6. Operating Mode for All Models Different messages/strings will be displayed on the LCD screen corresponding to different UPS operating modes, as shown in the following table 6.1. Different Warning/fault code, as shown in the following table 6.2. Only one normal operating string or fault string is presented a time. However if several warnings happen at the same time, they will be displayed on the LCD alternately.

UPS working in the No output mode. ■ Figure 6.4 The No output mode 6.5 EPO (Emergency Power Off) It is also called RPO (Remote Power Off). On LCD display, the word of “EPO” will be presented in the position of output voltage. It is a special status which the UPS will shut the output off and send out alarm.
CVCF mode can be enabled through the LCD setting or the software (Winpower, etc.). 2) The normal power rating will be derating to 60% in converter mode. 6.8 Abnormal mode In abnormal mode such as Bus fault etc., the corresponding fault string would be shown on LCD display to indicate the status of the UPS, and the background light will become red color.
7.
