AC Distribution Box (Type A-to-Type B) Replacement Procedure
NOTE:
The AC Distribution Box Type-A supports two ranges of AC power input: 100V-120V or 220V-240V.
The AC Distribution Box Type-B is a lightweight unit, supporting AC power input of 1OOV - 240V.
The Type-B unit has the following features.
•
Since it automatically supports a power range of 1OOV - 240V, it is not supplied with jumpers
(to alter the input power).
•
It does not support peripheral power outlets.
•
It is fitted with an On/Off power switch
(unlike a Type-A unit that has a circuit breaker switch).
In place of a circuit breaker switch, the Type-B unit is fitted with two fuses:
•
The unit does not contain a fan.
NOTE:
The procedure below applies to replacement of an old-type AC Distribution Box Type-A with a new-type
AC Distribution Box Type-B. In this scenario, the following information is applicable:
1.) Required Use of USB Isolator
If an approved peripheral was previously connected to a Vivid S5 N / Vivid S6 N system that was
fitted with an AC Distribution Box
Type-A
, after the installation of a
Type-B
AC Distribution Box, any
approved non-medical-grade peripherals should be connected to an external power supply.
In addition, these peripherals must be connected to the USB port on the system using a USB
isolator (P/N 5459394) as shown in
2.) Blanking AC Outlet Ports on Left Rear Cover
It is necessary to blank the two AC Outlet ports (previously used for connection of peripherals) on
the Vivid S5 N / Vivid S6 N Left Rear Cover, using the plastic AC Outlet Cover (P/N 5446701) which
is supplied in the AC Distribution Box Kit. In addition, a plain white label is used to cover the power
details (Max. 250VA Total), now no longer relevant - see
