Signs
Operating Instructions
Version 1.5
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.

2.11 Training
Operating Instructions
Version 1.5
2.11 Training
The safety regulations specify that all employees must be trained. However,
due to the fact that not all employees are exposed to the same degree of
danger, extensive training is not necessary for each individual.
In order to determine how much training any given employee requires, each
employee is assigned to one of three different categories, each with its own
level of training:
1. Authorized Employees
These employees install the locks and warning signs, and perform
maintenance and service work. They must have well founded
knowledge of energy regulation for this reason.
Firstly, they must be able to pinpoint and measure all energy sources.
They must also be capable of locating energy sources which cannot be
recognized as such at first glance, for example electrical energy, kinetic
energy, chemical energy and thermal energy. After authorized
employees have mastered these tasks, they must be taught to enable,
regulate and release energy in a safe manner.
2. Effected Employees
This classification includes employees who operate the machines or
components which are to be deactivated. Employees who work in an
area with equipment which must be locked, or which must be identified
as locked, are included in this classification as well. These employees
must be made aware of the basic nature of energy regulation. They
must understand why the locking and identification procedure is so
important, what the locks and warning signs look like and why they must
not be removed.
3. All Other Persons
This classification encompasses all persons who are neither authorized
nor effected employees. This group consists of office personnel,
engineers, supervisors and general management. Although these
persons have no direct contact with the equipment to be locked or
identified as locked, a certain amount of training is nevertheless
appropriate.
The company department which is responsible for safety matters must
conduct audits at regular intervals, in order to assess the locking and
identification procedure. Within the framework of these audits, the safety
inspector must document the extent to which the various aspects of the
procedure are being adhered to. Depending upon the results of the audit, the
safety department shall either conduct a formal examination of the
procedure, or arrange for retraining.
