The "manual bypass" switch  28  is used to
remove Pulsar EX for maintenance
purposes or standard exchange, while
guaranteeing continuity of power supply to
your loads.
Operating mode:

c

 switch the "manual bypass"  28  from the

"NORMAL" position to the intermediate
position (see figure 9);

c

 check that, in this position, the "automatic

bypass" has been put into operation:
indicator light  1f  is flashing;

c

 if the indicator light  1f  is still on, the

transfer to the "automatic bypass" has not
taken place (power voltage or frequency not
within the operating range). In this case do
not switch to the "BYPASS" and call our
after-sales service.

c

 move the "manual bypass" switch   28

from the intermediate to the "BY-PASS"
position. The display should show:

with another UPS of the same type, without
interrupting your load. In this case do not
forget to unplug and store the "automatic
bypass" cartridge  21 .
