2.5.1 Main switch switched off - machine system connected to the main power
supply
The following table shows the voltages of the individual modules when the main switch is switched
off, but the placement system is still connected to the main power supply. 2
DANGER 2
The following components still carry potentially lethal voltages even if the main switch is switched
off: 2
– cable connection terminals 1, 3, and 5 of S1 main switch
– Z1 main power filter
– BU1 service socket
– F1 automatic circuit breaker for the service socket
– The color of all individual wires, which still carry potentially lethal voltages even if the main
switch is switched off is brown.

2.5.3 Compressed air conditions in the machine after switching off at the main
switch
When the placement system is switched off at the main switch (item 1 in Figure 2.5 - 1) or the
power supply to the placement system fails, the electrically-controlled main valve Y1 shuts off the
compressed air unit (item 3 in Figure 2.5 - 1
). The pressure drops to 0 bar within 5 seconds. 2

2.6 Lock out and tag out procedure
2.6.1 Purpose and scope
Before performing any maintenance work or service work, a procedure of locking and tagging
must be followed. The procedure, when followed correctly eliminates the possibility of an em-
ployee being injured. 2
NOTE 2
These procedures represent the minimum lock/tag out requirements. Any additional safe-guards
needed to complete work safely can be specified by facilities supervision, the safety officer, the
safety committee and the health department.
2
2.6.2 Description
Whenever it becomes necessary to isolate, control and release energy, the following procedure is
to be followed 2
(1) Notify affected employees.
(2) Shut down equipment, using normal stopping procedures, such as
– depressing the stop button
– shutting down the station computer or
– switching off the placement system at the main switch.
(3) Isolate the equipment from all its energy sources such as
– compressed air supply and
– power supply.
(4) Lock Out equipment.
– Apply the lock and the lockout whenever possible.
