Operating Procedure - Black Box Local Mux-6 User Manual

4.3 Operating Procedure

BEFORE SWITCHING ON THIS INSTRUMENT, the protective earth
terminals of this instrument must be connected to the protective
conductor of the (mains) power cord. The mains plug shall only be
inserted in a socket outlet provided with a protective earth contact. Do
NOT use an extension cord (power cable) without a protective conductor
(grounding).
Make sure that only fuses with the required rated current are used for
replacement. The use of repaired fuses and the short-circuiting of fuse
holders must be avoided.
Whenever it is likely that the protection offered by fuses has been
impaired, the instrument must be made inoperative and secured against
any unintended operation.
Turning On the Power
Apply AC power by connecting the AC power cord to an acceptable AC
source. If the power indicator lights, then the Local Mux-6 is powered.
If the local and remote Local Mux-6 units are in operation and properly
connected via the main channel, no other indicator should be ON. If any
other indicators light, refer to Section 4.5 for troubleshooting information.
Operation
The Local Mux-6 operates entirely unattended except when performing
system tests.
Turning Off the Power
To turn off Local Mux-6, simply remove the AC power cord from the AC
source.
Operational Field Strapping Changes
If you need to reconfigure the Local Mux-6 for twelve-channel mode
or six-channel mode, follow the appropriate set-up procedure described
in Section 3-2.
