5 Operating Instructions
Final UPS Operating Mode:
The UPS is now in normal operating mode, as described in chapter
"2.1. Stand-alone unit", "3.1 Hot standby systems" or "4.1 Parallel
systems". The green LEDs (L1, L2, L5, L3, L16, L17, L26, L19) on
the operating panel(s) must be illuminated (but not flashing).
Should a problem arise during the Switching On, please follow the
instructions in JUE 401066, Initial Start-up.
Note 1: For Parallel Systems.
If the bypass is off, the output is not supplied and the system has
multiple internal maintenance bypasses and the load is connected,
the load may be excessive for one bypass only. In this case, it is
better to switch off the load or proceed further without switching on
IBY (the static bypasses will only switch on together when enough
are ready to take the load.)
