disconnecting Pulsar EX

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.

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 .
