2.7.4

Electrical safety

If covers are opened or parts are removed which are only accessible with tools, voltage-
carrying components may be exposed. The plugs may also be under voltage. There is a risk
of electric shock!
f Electrical work must only be carried out by your authorized service partner.
f Before connecting the device, check that the supply voltage and frequency are correct
at the point of installation (see Electrical data and information on the type plate in the
Operating Instructions, "Supporting documents", page 36).
f To avoid injury to the user and for cooling reasons and fire protection, never remove the
housing covers.
f Observe the manufacturer's installation instructions for house installation ("Supporting
documents", page 36, Checklist for your PrograMill system).
f To avoid the risk of electric shock, only connect the device to the power supply with a
protective conductor, do not reach into the connections on the right side of the housing
or manipulate them and do not reach into the housing interior via the service flap and
the tool changer.
f The mains plug is used as a supply circuit disconnecting means. Always connect the
mains plug to an easily accessible protective contact socket.
f Protect the cable against damage due to heat, moisture, oil, sharp edges, pressure and
crushing. In the case of damaged cables, replace only with the original spare parts.
f The device and the suction unit must be connected to a grounded and freely accessible
protective contact socket, each in a separately protected circuit. Make sure that there
are no devices connected which cause strong mains voltage fluctuations when they are
switched on. These fluctuations interfere with the electronic controls and may cause
failure of the system.
f Make sure that the protective contact sockets are equipped with a residual current
circuit breaker (FI).
f If you need to disconnect the unit from the power supply at a later time: Disconnect the
plug from the mains socket, not on the device.
2.7.5 Pneumatics
The pneumatic components in this device are under high pressure. Sudden escape of
compressed air through leaking pipes and connections or swirling hoses can cause serious
injuries and damage to hearing.
f Ensure that only personnel with additional pneumatic training perform work on
pneumatic components.
f Ensure that the compressed air supply meets the required system specification (see
Requirements on incoming compressed air in the Operating Instructions, "Supporting
documents", page 36). Do not exceed the maximum permissible pressure.
f Ensure that the compressed air is clean, oil-free and dry.
f Ensure that the pneumatic components are checked regularly.
f Ensure that all defects, such as loose connections, damaged cables, etc., are dealt with
immediately.
