Once the ground switch is closed, it can be locked in the "Closed" position by
removing the cable from the receptacle on the device and locking the sliding
cover that permits access to the receptacle and manual "Push to Open" button.
OPENING
The grounding switch can be opened by manual operation of the "Push to Open"
button, located behind the sliding cover on the device front panel, Figure 3. If
electrical trip is provided at the control switch (not recommended), for safety
reasons the switch is prevented from opening in less than 20 seconds after
closing.
INTERLOCKS AND SAFETY FEATURES
The device is designed to provide as many interlocks and safety features as
practical for the personnel performing any of the operations described earlier.
The device cannot be levered into or out of the "Connected" position unless the
ground switch is open:
• Upon levering a device with a closed grounding switch into or out of the "Test"
position, the switch is tripped open by the floor tripper in the compartment.
• In the "Connected" position, the levering crank is prevented from being
engaged with the levering screw unless the grounding switch is tripped first.
• An indicator on the front panel shows the status of the ground switch contacts
– "Open" or "Closed", Figure 3.
