EMERGENCY STOP / OFF actuators shall be identified by the tors which, when actuated several times, act alternately as a
color RED. START / ON and STOP / OFF actuator.

STOP / OFF actuators The colors YELLOW and GREEN shall not be used. The color

START / ON actuators WHITE, GREY and BLACK are preferred colors for actuators
WHITE, GREY and BLACK are the preferred colors for which cause a movement while they are actuated and stop

devices and the equipment to start, with the main prefer- jogging actuators). GREEN is also permitted. RED shall not

Use of WHITE and BLACK for specific meanings RESET Actuators (used, for example, with protective relays)
Where the colors WHITE and BLACK are used to distinguish shall be BLUE, WHITE, GREY or BLACK, except RESET actua-
