Never fit a switch cap if the current indicator
window shows a red flag.
1. Check that the overcurrent indicator (a) has been reset
(no red flag is shown).
2. Put a switch cap on the springing handle until the
spring catch (b) engages.
3. Remove the cover from the cast resin insulated
member of the relevant switch in the fixed section.
4. Position the switch cap on the cast resin insulated
member of the switch, with the spring-mounted cam
located to the left, until the cap abuts the stop.
5. Next, push in the handle firmly.
 The moment the force exerted on the handle
exceeds a certain value, the resistance of the
spring cam is overcome and the cap is switched on.
