Switching On the
Power
The mains contactor in the DDC can be switched on if the wiring has been
laid out as per the INDRAMAT terminal connecting diagram and the E-stop
sequence is closed. An error can immediately cause dangerous drive move-
ments. The following instructions must be observed.

Possible consequences:
Danger to life and limb and property damage.
How to avoid:
The protection of personnel must be secured in the
plant by taking superordinate steps. These steps
are plant-specific and must be determined by the
manufacturer after an analysis of the possible dan-
gers and faults. Observe all safety instructions of
the plant.
Observe the following in particular:
• Personnel must be kept clear of the machine
movement range. Possible measures to prevent
personnel unintentionally accessing the machine
are protective fences, protective railings, protec-
tive coverings and light curtains or barriers.
• Fences and coverings should be strong enough
to withstand maximum possible momentum.
• E-stop switches must be mounted in the imme-
diate vicinity of the operator so these can be
easily reached. Check that the E-Stop sequence
works before starting up.
• Make sure the drives are brought to a standstill
before accessing or entering the danger zone.
• Avoid operating high-frequency, remote control
and radio equpment near the equipment electro-
nics and supply leads. If use of such a unit
cannot be avoided, check the system and the
plant for possible malfunctions at all positions of
normal use before the first start-up. If necessary,
carry out a special EMC test on the plant.
• Do not use a very high setup speed (parameter
A101). The user must be able to bring the plant or
machine to a standstill with the use of the E-stop
switch and before serious damage can occur.
