LETHAL VOLTAGES EXIST WITHIN THE CABINET, EVEN WHEN THE UNIT IS DEENER-
GIZED. ONLY QUALIFIED SEVICE PERSONNEL WITH ADEQUATE TRAINING MUST

5.2. DESCRIPTION OF AC INPUT AND AC OUTPUT TERMINALS BLOCKS
The AC Input, AC Output Terminals Blocks are provided for the connection of incoming power and the con-
nection of the load (equipment) intended to be powered by the UPS. Refer to Figure 13—Component layout
for these connections and their locations in the UPS Cabinet.
5.3. MANUAL BYPASS SWITCH DESCRIPTION
In most units, this switch is located on the inside of the left door of the system (see Figure 13—System
Component Layout for exact location). The bypass switch is used in case of a failure of the lighting in-
verter. If the lighting inverter fails, place the bypass switch in the “MAN” position. In this position the in-
verter section is bypassed allowing the load to be powered by the utility until the inverter can be repaired.
In case of system failure, contact factory for service. The Manual Bypass Switch is used to bypass the
electronic (inverter) when the system have failed. The Manual Bypass Switch should never be operated
when the UPS is supporting the load. The rotation of this switch will turn off the inverter. The Load will be fed
from the Utility until the switch is place back into the UPS position, and the inverter is returned back to opera-
tion.
LETHAL VOLTAGES EXIST WITHIN THE CABINET, EVEN WHEN THE UNIT IS ON BY-
PASS. ONLY QUALIFIED SEVICE PERSONNEL WITH ADEQUATE TRAINING MUST
SERVICE THIS EQUIPMENT.
