MXI101V TECHNICAL SERVICE MANUAL
Avoid wearing loose clothing and personal jewelry such as rings, watches, and chains when working near
energized circuits. Make a habit of removing all jewelry and storing it in a safe place as soon as you enter the
transmitter building.
Before beginning work,
shut off all AC to the transmitter power supplies. Tag and lockout the switches.
Your safety routine must ensure that the person placing the tag and locking the switch is the only person who
removes it and reactivates the switch. You might want to include the AC to the remote control as well, if there is
any possibility that a studio worker could unknowingly activate the transmitter while you are working on it. One
way of ensuring that the lockout "placer and remover" are the same person is to issue individual padlocks to each
person on the transmitter technical staff.
You might want to include your tower contractor's rigging crew in the list of people who are allowed to use tags
and padlocks. As an alternative, Dielectric™ makes a transmission line lockout switch that is intended for riggers
to turn off and lock out any RF before climbing over the antenna to replace light bulbs, etc.
Proper grounding is
vital
. Make ground inspection a part of your maintenance program; someone's life could
depend on it.
