9.2 Maintenance
Testing the residual-current-operated
protective device
The residual-current-operated
protective device is only availa-
ble with the CS351E Compact
System for ErgoSpin hand-held
nutrunners.
Check the function of the residual-current-
operated protective device (RCD) by actua-
ting the test button. Unless otherwise spe-
cified, 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 vol-
tage for the power and controller electro-
nics will be maintained. Only the main cir-
cuit will be isolated.
NOTE
Damages to the compact system

Do not press the test button while
tightening.

If the residual-current-operated pro-
tective 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").
