[PSES] Shorting switch - appropriate markings

[Doug Powell]

Hello all, As we all know there are a variety of ON & OFF symbols available with slightly different usage depending on the situation. IEC 60417-5007 Power ON IEC 60417-5008 Power OFF IEC 60417-5009 Standby IEC 60417-5010 ON-OFF IEC 60417-5011 ON/OFF, push button IEEE 1621 Sleep Mode I now have a situation where I want to use a shorting switch on equipment to prevent a stored energy hazard while in maintenance mode. The idea is to provide instructions on how to discharge the equipment and then close the switch to prevent a voltage build up until maintenance is complete, then open the switch.  My concern is identifying the appropriate symbol to place next to the switch positions.  None of the above seem appropriate.  In addition I have searched through  ISO 7000 and 7010 with no luck. Can anyone suggest an internationally recognized symbol for this purpose?
