2.8.1 Placement system switched off at the main power switch, but still connected ...
The following table specifies the voltages of modules when the automatic placement system is
switched off at the main switch, but still connected to the mains supply.
WARNING 2
The following components still carry potentially lethal voltages even if the main power switch is
switched off:
– Cable connection terminals 1, 3, and 5 of the S1 main power switch
– Mains filter Z1
– 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
power switch is switched off, is brown.

The automatic placement system is unpowered, apart from slight residual voltages in the servo
unit.
2.8.3 Compressed air conditions in the machine after switching off at the main
power switch
When the system is switched off at the main power switch (item 1 in Fig. 2.8 - 1) or if the power
supply fails, the electrically-controlled main valve Y1 of the compressed air unit closes (item 3 in
Fig. 2.8 - 1
, page ). The pressure will drop to 0 MPa (0 bar) within 5 seconds.

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