The following table specifies the voltages of modules when the placement system is switched off
at the main switch, but still remains connected to the mains supply.
DANGER
The following components still carry potentially lethal voltages even if the main switch is switched
off:
– Cable connection terminals 1, 3, and 5 of S1 main switch,
– Z1 mains filter,
– BU1 service socket,
– F1 automatic circuit breaker for the service socket.
– The color of all single wires, which still carry potentially lethal voltages even if the main switch
is switched off is brown.

When the system is switched off at the main switch (item 1 in fig 2.4 - 1) or if the power supply
fails, the electrically controlled main valve Y1 of the compressed air unit closes.
(Item 3 of fig 2.4 - 1
). The pressure will drop to 0 bar within 5 seconds.

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
employee being injured.
NOTE
These procedures represent the minimum lock / tag out requirements.
Any additional safe - guards needed to complete work safely can be specified by supervision fa-
cilities, the safety officer, the safety committee and the health department.
'HVFULSWLRQ
Whenever it becomes necessary to isolate, control and release energy, the following procedure is
to be followed
(1)Notify all involved employees.
(2)Shut down the system and all equipment, using normal stopping procedures, such as
– pressing 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 up the system
– Fasten a lock wherever possible, e.g. on the
motor protection switch.
