ensure that they are used properly and in accordance with this handbook and any other instructions provided
by Seller. Racal Instruments products are not specifically designed, manufactured or intended to be used as
parts, assemblies or components in planning, construction, maintenance or operation of a nuclear facility, or
in life support or safety critical applications in which the failure of the Racal Instruments product could create

such unintended application, Buyer shall indemnify and hold Racal Instruments, its officers, employees,

FOR YOUR SAFETY
Before undertaking any troubleshooting, maintenance or exploratory procedure, read carefully the
WARNINGS and CAUTION notices.
This equipment contains voltage hazardous to
human life and safety, and is capable of
inflicting personal injury.
If this instrument is to be powered from the AC line (mains) through an auto-
transformer, ensure the common connector is connected to the neutral (earth pole)
of the power supply.
Before operating the unit, ensure the conductor (green wire) is connected to the
ground (earth) conductor of the power outlet. Do not use a two-conductor extension
cord or a three-prong/two-prong adapter. This will defeat the protective feature of the
third conductor in the power cord.
Maintenance and calibration procedures sometimes call for operation of the unit with
power applied and protective covers removed. Read the procedures and heed
warnings to avoid “live” circuit points.
Before operating this instrument:
1. Ensure the proper fuse is in place for the power source to operate.
2. Ensure all other devices connected to or in proximity to this instrument are properly grounded or
connected to the protective third-wire earth ground.
If the instrument:
- fails to operate satisfactorily
- shows visible damage
- has been stored under unfavorable conditions
- has sustained stress
Do not operate until, performance is checked by qualified personnel.

FUNCTIONAL
DESCRIPTION The 1260-100X Adapt-a-Switch Carrier (currently without Option
01T) is a two-slot VXI bus module that may contain up to six X-
series Adapt-a-Switch plug-in cards. The X-series Adapt-a-Switch
cards are 3.3” longer and 0.4” wider than the non X-series cards,
thus allowing higher density relay configurations.
You may leave some slots unoccupied for future expansion.
Each plug-in has its own unique configuration of relays or digital
testing capabilities, such as:
