2.10 Locking the System and Attaching Warning Signs
Before maintenance or service work is performed on the system, it must be
secured against possible start-up, and appropriate warning signs must be
attached.
Note!
This procedure includes minimum requirements for locking the system and
attaching warning signs before beginning maintenance and service work.
Additionally required safety precautions may be specified by the work
safety department, the safety inspector, the safety committee and the
employee health department.

2.10.1 Procedure
If you have to power off the system, please always follow the below-de-
scribed proceeding.
1. Instruct all employees affected in the working area.
2. Switch off the system. Please proceed to the standard switching off.
3. Five definite safety rules for working in de-energized state (according to
DIN VDE 0105):
– disconnect the system:
– prevent unintentional restart. (Attention! Tension between mains fil-
ter and main switch.)!
– deenergize (Attention! Frequency converter stores electric energy).
– earth and short-circuit.
– make sure that surrounding system parts under voltage are covered
and protected against touching.
4. Lock the system.
– Lock the mains switch with a padlock.
– Attach warning signs if locking is not possible.
Employees are thus informed that the system has been shut down for
the performance of service work. The sign must be securely attached.
It must be legible from all sides, and may only be removed by the per-
son who attached it.
5. Release all stored energy.
Stored energy in the coolant water circuit and electrical energy in
electrolytic capacitors must be released through the implementation of
appropriate measures. After switching the system off, wait for
approximately two minutes, after which work can be safely performed
on the system.
The following steps must be completed in order to once again prepare the
system for operation:
1. Inspect the work area: Make sure that authorized personnel have
removed all utilized tools, and that all safety devices are reactivated.
2. Inform all personnel in the effected area that the system will be started
back up again.
Warning!
During operation, the system may only be switched off with the mains
switch in the event of an emergency.
Shut down the operating system properly before switching the system off.
If the system is switched off during operation without first properly shutting
down the operating system, the cool-down cycle is not activated and the
system, as well as the PC, may be damaged.

3. Remove the locks and warning signs.
Each authorized employee must remove his own lock and store it
securely.
4. Switch the system on. Request authorized personnel to determine
whether or not repairs or maintenance work have been properly
executed while the system is running.
2.10.2 Testing
Maintenance personnel or electricians may test the system’s circuits by
activating them briefly without rescinding the locking procedure, as long as
no-one is still working on the components to be tested.
It is extremely important to identify all other start buttons with “Do not place
into operation” warning signs in order to prevent inadvertent start-up of the
system during testing.
2.10.3 Responsibility and Duties
1. It is the responsibility of maintenance personnel and the electricians to
assure that this procedure is adhered to.
2. It is the responsibility of the direct supervisor of maintenance personnel
and the electricians to instruct employees with regard to this procedure.
3. In cooperation with the safety committee, public health authorities, the
managers of the various company departments and the vice president,
it is the responsibility of the safety inspector to enforce the procedure for
locking the system and attaching warning signs.
2.10.4 Disposal
With the disposal in Germany the Closed Substance Cycle Waste Manage-
ment Act (KrW-AbfG) will apply. With wastes requiring special supervision
the record of waste disposal is to be provided.
With the disposal within EU as well as in the remaining foreign countries the
environmental and disposal regulations of each country are to be observed.
Only the disposal according to regulations protects human and environment.
