Type 4
Equipment is energized. Energized circuits are exposed and inadvertent
contact with uninsulated energized parts is possible. Potential exposu-
res are greater than 30 volts rms, 42.4 volts peak, 60 volts dc, or 240
volt-amp in dry locations. Potential exposures to radio-frequency cur-
rents, whether induced or via contact, exceed the limits in Table A5-1
of Appendix 5 (SEMI S2 guideline).

Transport
The COBRA DS vacuum pumps are tested and checked in our factory
before careful packing. Check the packaging for transport damage
when the goods arrive. The pump can withstand temperatures bet-
ween -25°C and +55°C during transport.
Transport in packed state
Packed on a pallet, the vacuum pump can be moved with a hand for-
klift truck.
Transport in unpacked state
The vacuum pump is fastened to the pallet with fixing pins:
u
Unscrew the fastening nuts underneath the pallet.
CAUTION
Do not work, walk or stand under suspended loads.
CAUTION
Please check out the weight of the vacuum pump before lifting it up
(see "Technical Data").
Use adequate lifting gear for this.
NOTE:
The suspension eyes are located at about the center-of-gravity
of the vacuum pump. If the vacuum pump is equipped with accessories
that could influence the center-of-gravity, this must be taken into ac-
count when lifting and a belt must additionally be attached to a speci-
fic point.
l
Fasten the hoist to the suspension eye(s) on the cylinder
l
Use a hoist that is equipped with a hook and safety lock
l
Lift the vacuum pump
If the pump is fastened to a pallet with fixing pins:
u
Unscrew the fixing pins in the base frame
CAUTION
In case of a vacuum pump filled with oil, make sure that by lifting
the inclination angle of the vacuum pump do not exceed 5° from
the horizontal. In case of too high inclination (>5°), risk of oil leak
within the work area.
Make sure before every transport using the appropriate lifting mean
that the inclination of the vacuum pump is less than 5°.
The packaging material must be disposed of in accordance with local
and national regulations.
