Chapter 3 - System Installation
Ring Generator Unit Installation
The Ring Generator Unit (RGU3) is needed if a SLIB is to be installed in a Cabinet. The RGU3
provides ring voltage and a Message Wait Source. A cable for connecting the RGU3 and KSU
is provided.
1. Mount the unit inside the Cabinet to the bottom side panel on the right with the two
screws provided.
2. Connect the unit to the backplane via CN14 connector (marked on PCB).
Power Supply Unit Installation
The Power Supply Unit (PSU) provides power for the system boards and telephones,
converting AC voltage input to appropriate DC voltages.
Voltage Selector Switch
The PSU can operate from either 110/115 or 220/230 Volts AC based on the setting of the AC
SELECT switch on the lower front of the PSU.
†
If local AC is 115 volts, move the switch to the left position to display “115”.
†
If local AC is 230 volts, move the switch to the right position to display “230”. Default setup
of the product is 115VAC.
The range of input voltage and the fuse rating of the PSU are as follows:
Power Capacity
The power capacity of the PSU is as follows:
Although, the PSU is equipped with power-line transient protection, an external
Power Line Surge Protector should be installed at the AC outlet to give additional
protection, especially during violent thunderstorm activity. Refer to
“Lightning
Protection”
.
