Setting Up and Transporting the PG 760
Unpack your PG 760 programming device as follows:
1. Remove the packing.
2. Do no throw the original packing away. Keep it in case you have to
transport the unit again sometime in the future.
3. Check with the packing list to make sure no components are missing.
4. Check the packing and its contents for any shipping or transport damage.
5. Please inform your local dealer of any shipping or transport damages and
and of outstanding items indicated on the packing list.
!Caution
Risk of mechanical damage!
When transporting your PG 760 in cold weather when it may be exposed to
extreme variations in temperature, make sure that no moisture or
condensation can form on or in the unit.
The unit should be allowed to reach room temperature slowly before it is started
up. If condensation has formed, the unit should be left for about 12 hours before
being switched on.
Fill the serial number of your programming device in the table below. If your
device has been stolen and repair work is required the repair and maintenance
centers can only identify it by its serial number.
Serial number PG 760
Setting up the tower:
Proceed as follows:
1. Place your programming device on a horizontal and even surface.
Don’t cover the ventilating slots.
2. Place monitor and keyboard in the most convenient position.
3. Connect monitor and keyboard.
Despite the fact that the PG 760 is of rugged design, its internal components
are sensitive to severe vibrations or shock. You must therefore protect your
PG 760 against severe mechanical stressing when transporting it. Use the
original packing material if you have to ship the PG from one location to
another.

Risk of overheating!
If you cover up the slots for the inlet and outlet air in any way, there is a risk
that your PG 760 or its power supply will be damaged.
Observe the following notes concerning the power supply of the unit.
Note
The power plug must be disconnected to isolate the unit completely from the
supply.
Note
For operation in Canada and the US a UL listed, CSA Labeled Cord Set must
be used. The unit is intended for operation with normal grounded power supply
networks (referred to as TN systems according to IEC 364-3).
The unit is not intended for operation with non-grounded or impedance-groun-

If the set voltage does not correspond with your local voltage, you must
select the correct voltage by moving the mains voltage selector either to
115 V or 230 V.
!Caution
Risk of damage to the unit!
Operating the PG 760 with the incorrect mains voltage can damage the unit
since the input voltage is also applied to the mains outlet.
To operate the monitor, observe the manufacturer’s specifications.
Only a monitor with the following rated currents may be connected:
115 V 1 A max.
230 V 0.5 A max.
