Auto restart mode the battery may become exhausted following an extended ac mains failure the inverter shuts down when the battery reaches the end of discharge voltage eod the ups may be programmed to system auto start mode after eod the system starts after a delay time when the ac mains recover the mode and the delay time are programmed by the commissioning engineer 14
Fig 8 eco mode operation diagram 14
Frequency converter mode by setting the ups to frequency converter mode the ups could present a stable output of fixed frequency 50 or 60hz and the bypass static switch is not available 14
There is a short interruption time less than 10ms when transfer from eco mode to battery mode it must be sure that the interruption has no effect on loads 14

Than 50 m and the length of the dc power cables are no longer than 30 m 17
The recommended cable section for power cables are only for situations described below 17
The size of neutral lines should be 1 1 times the value listed above when the predominant load is non linear 17
Attention 18
Cables to the output terminal 18
Connect the battery cables to the battery terminal 18
Connect the protective earth wire to protective earth terminal pe 4 connect the ac input supply cables to the input terminal and ac output supply 18
Connecting power cables the steps of connecting power cables are as follows 1 verify that all the switches of the ups are completely open and the ups internal 18

Terminal battery terminal and protective earth terminal are shown in fig 4 18
The cb with rcd residual current device is not suggested for the system 18
Ups external air breaker recommendations are shown in table 3 18
Attention 19
Check to make sure there is no mistake and re install all the protective covers 19
Control and communication cables 19
Dry contact interface dry contact interface includes port j2 j9 and the functions of the dry contact are shown in table 3 19
In fig 5 19
Interface rs232 rs485 snmp parallel card interface and usb port as it is shown 19
The rear panel of the cabinet provides dry contact interface j2 j9 and communication 19
Warning 19
Battery warning output dry contact interface the input dry contact j2 and j3 can detect the temperature of batteries and environment respectively which can be used in environment monitoring and battery temperature compensation interfaces diagram for j2 and j3 are shown in fig 6 the description of interface is in table 3 20
Bcb input port 21
Remote epo input port j4 is the input port for remote epo it requires shorting nc and 24v during normal operation and the epo is triggered when opening nc and 24v the port diagram is shown in fig 7 and port description is shown in table 3 21
Temp_bat 21
Temp_env 21
Battery warning output dry contact interface 22
The default function of j6 and j7 are the ports of bcb the port diagram is shown in fig 8 and description is shown in table 3 22
The default function of j8 is the output dry contact interface which presents the battery warnings of low or excessive voltage when the battery voltage is lower than set value an auxiliary dry contact signal will be activated via the isolation of a relay the interface diagram is shown in fig 9 and description is shown in table 3 22
Commissioning and maintenance by authorized engineers or can be used for networking or integrated monitoring system in the service room snmp used on site installation for communication optional 23
Communication interface rs232 rs485 and usb port provide serial data which can be used for 23
General alarm output dry contact interface 23
Parallel card interface cabinet parallel optional 23
