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:

cswitch the "manual bypass" 28 from the "NORMAL" position to the intermediate position (see figure 9);

ccheck that, in this position, the "automatic bypass" has been put into operation: indicator light 1f is flashing;

cif 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.

cmove the "manual bypass" switch 28 from the intermediate to the "BY-PASS" position. The display should show:

	…	1a to 1c off

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 .
