Testing the residual-current-operated
protective device
The residual-current-operated
protective device is only available
with the CS351E Compact System
for ErgoSpin hand-held nutrunners.
Check the function of the residual-current-
operated protective device (RCD) by actuating
the test button. Unless otherwise specified, we
recommend performing this test once a month,
but at least every six months.
If the residual-current-operated protective
device has been triggered, the control voltage for
the power and controller electronics will be
maintained. Only the main circuit will be isolated.
NOTE
Damages to the compact system
Do not press the test button while

tightening.
If the residual-current-operated protective

device has been triggered, only switch it on
again after tightening has been completed
(abort by the controller).
1. Actuate the test button. The residual-
current-operated protective device must
be triggered (position "0").
2. Switch the residual-current-operated
protective device back on (position "1").
