15/20 KVA Rear panel | 5.3 Connection to mains and loads (4000 - 20000 VA) | ||
Only qualified specialists or technicians who conform to applicable safety | |||
(ISO and With ISO) | |||
standards may carry out the installation of this equipment. The installation must | |||
| further comply with all local legislation and regulations. | ||
| Follow all installation and safety instructions very carefully, otherwise those | ||
| performing installation may suffer from a hazardous situation and the UPS or | ||
| load connections may also be damaged. | ||
|
| The high voltage and current contained within the UPS equipment can injure | |
|
| or kill personnel and damage equipment. | |
| For electrical installation, closely observe the nominal current rating of the source. | ||
| Installing External battery cabinets | ||
| z | First disconnect the UPS from mains and loads before attempting an | |
|
| External Battery Cabinet installation. | |
| z | Use the battery cable provided with the External Battery Cabinet to | |
|
| connect the External Battery Cabinet to the UPS. Connect a second | |
|
| battery cabinet to the first one with the cable provided if more than one is | |
|
| to be installed. | |
| z | Be aware of UPS parameters and changing the Battery pack quantity | |
|
| when using the external battery cabinets (see chapter 7.2) | |
| Installing UPS | ||
| z | Ensure that the installation site has all electrical connections properly | |
|
| carried out. In addition, refer to figures 2 and 3 to check the fuse and | |
|
| cable dimensions. | |
| z | Isolate and secure the source against reclosing. Both input and output | |
|
| circuit breakers (located in the back) must be “OFF”. | |
| z | Refer to figure 2 for single cable input and figure 3 for dual cable input. | |
|
| Connect the UPS according to these diagrams. If installing dual cables, | |
|
| the interconnection jumper (b*) needs to be removed as in figure 2. Fuse | |
|
| and cable sizes are given in figure 3. | |
| z | During installation, if it cannot be determined that neutral is grounded or | |
|
| the identification of the neutral status of the mains supply is unreliable, | |
|
| an additional two pole disconnect device is necessary in the building | |
|
| installation. | |
| z | At the back of the unit you will find the Emergency Power Off (EPO), | |
|
| which when open will immediately shut down the logic circuit output of | |
|
| the UPS as in figure 2 and 3. Wiring the EPO signal is optional. | |
| z | Caution! Local safety requirements may require a separate external | |
|
| Emergency Power Off that opens output circuit breakers, and if so, use | |
