Dangerous currents due to insuffi-
cient ground conductor connec-
tions!
The ground conductor connec-
tions may not be influenced by me-
chanical, chemical or
electrochemical means. The con-
nection must be permanent.
The FI safety switch is deactivated
by residual currents from the inter-
mediated circuit and the power
supply filter. It is therefore not per-
missible to operate the boxes on FI
safety switches!
Operation on unsymmetrical pow-
er supplies (one phase is ground-
ed) is not permitted!
The system boxes are designed for
operation in industrial environ-
ments (emission class A), i.e.
–no direct connection to the
public low voltage power supply,
–connection to medium or high
voltage line using a transformer.
Once the device has been swit-
ched off it cannot not be switched
back on again until 30 seconds
have elapsed.
Before working on the X0 power
supply connections or on the X21
on SB305 voltage selector termi-
nals, allow for a discharging time
of 3 minutes after turning off the
power. Always check the connec-
tions and terminals for current!
