6.3.1
Performing high-voltage testing
If high-voltage testing of the control cabinet or the power
supply as a stand-alone component is planned during final
inspection and testing, the following features must be
observed.
–
The power supply wiring must be implemented as
shown in the wiring diagram.
–
The maximum permissible test voltages must not be
exceeded.
Avoid unnecessary loading or damage to the power supply
due to excessive test voltages.

6.3.2
Disconnecting the gas-filled surge arrester
The built-in gas-filled surge arrester inside the device
ensures that the power supply is effectively protected
against asymmetrical disturbance variables (e.g.,
EN
61000-4-5).
Each surge voltage test represents a very high load for the
power supply. Therefore avoid unnecessary loading or
damage to the power supply due to excessive test voltages.
If necessary, the gas-filled surge arrester inside the device
can be disconnected in order to use higher test voltages.
Following successful completion of testing, please
reconnect the gas-filled surge arrester.
Figure 2
Disconnect gas-filled surge arrester
To disconnect the gas-filled surge arrester, proceed as
follows:
1.
Remove power from the unit.
2.
Unscrew the Phillips head screw completely and keep
the gas-filled surge arrester screw in a safe place. The
gas-filled surge arrester is now disconnected and is no
longer functional.
3.
Perform the surge voltage test on the power supply.
4.
Following successful high-voltage testing, screw the
gas-filled surge arrester screw fully back into the power
supply.
For the relevant applicable test voltages and
insulation distances, refer to the
corresponding table (see technical data:
electric strength of the insulation section).

DANGER: Risk of electric shock or
damage to the power supply due to using
the wrong gas-filled surge arrester screw
To connect the gas-filled surge arrester, only
use the gas-filled surge arrester screw that
was originally installed in the power supply.
