5.3 Operating in ECO (on bypass) mode
When the UPS system is operated in ECO (on bypass) mode the load is powered from the UPS bypass mains supply, via
the static switch, under normal conditions and transfers to the inverter (on inverter mode) automatically if the bypass
mains supply fails.
5.3.1 How to power-up the UPS system and operate in ECO (on bypass) mode
1. To power-up the UPS system from a fully shut down condition, follow the standard UPS system start-up instructions in
paragraph 5.2 but do not perform the ‘ "Transfer the load to inverter" ’ stage (step 15 onwards).
2. On the module control panel, after 60s verify that:
a) The LINE 1 LED is green.
b) The
LINE 2
LED changes to green.
c) The BYPASS LED is green.
d) The
INVERTER
LED is OFF.
e) The BATTERY LED is green.
f) The LCD displays
LOAD NOT PROTECTED.
5.3.2 How to transfer to ECO (on bypass) from on-line (on inverter) mode
The UPS can be manually switched to ECO (on bypass) from the on-line (on inverter) mode using the module control
panel load transfer menu.
1. On the module control panel (of any UPS module) press the
ENTER key once to access the menu system.
2. Using the UP/DOWN keys, move the cursor so that it is adjacent to COMMANDS and then press the ENTER key.
3. Using the UP/DOWN keys, move the cursor so that it is adjacent to LOAD TO BYPASS and then press the ENTER key.
a) The UPS system will transfer the load to the static bypass (on all UPS modules).
4. On the module control panel(s), verify that:
a) The INVERTER LED is extinguished.
b) The
BYPASS
LED is green.
c) The LCD displays LOAD NOT PROTECTED .
CAUTION: There will be a very short supply break when the UPS switches to the ‘on inverter’ mode, so you
should elect to operate the system in the ECO mode only if a load can withstand a brief power break.
CAUTION: Before you carry out this procedure, warn the critical load user that the load will not be supplied with
processed, backed-up power once the transfer to maintenance bypass has been performed.
