Mobile hoisting gear: Installing a cable bollard
Fig. 9:
Lifting equipment secured to a cable
bollard
If a mobile hoisting gear is used, install a cable bollard at the edge of the basin:
ƒ
Remove lifting equipment (e.g. wire rope) from the hoisting gear and secure to the
cable bollard.
ƒ
Secure the connection cable edge of the basin to prevent it from falling.
CAUTION! If the connection cable leads over the edge of the basin, beware of po-
tential abrasion. Sharp edges may damage the connection cable. Bevel the basin
edge if necessary!

Electrical connection
DANGER
Risk of fatal injury due to electrical current!
Improper conduct when carrying out electrical work can lead to death due to electric
shock!
• Electrical work must be carried out by a qualified electrician!
• Observe local regulations!
DANGER
Risk of explosion due to incorrect connection!
• Always connect the mixer to an electrical outlet outside the explosive area. If
the connection must be made within the explosive area, then the connection
must be carried out in an Ex-rated housing (ignition protection class
DIN EN 60079‑0)! Non-compliance will lead to a risk of fatal injury from explo-
sion!
• Connect the equipotential bonding conductor to the earth terminal indicated.
The earth terminal is installed in the area of the connection cable. A cable cross-
section in accordance with the locally applicable regulations must be used for
the equipotential bonding conductor.
• The connection must always be carried out by a qualified electrician.
• For the electrical connection, also note the additional information in the chapter
on potentially explosive areas found in the appendix of these installation and
operating instructions!

Mains connection corresponds to the information on the rating plate.
ƒ
Power supply on mains side with clockwise rotating field for three-phase AC motors
(3~ motor).
ƒ
Route the connection cables according to the local regulations and connect them
according to the wire assignment.
ƒ
Connect
all
of the monitoring devices and check their function.
ƒ
Secure the earthing in accordance with the local regulations.

Fuse on mains side
Circuit breaker
The size and switching characteristics of the circuit breakers must conform to the rated
current of the connected product. Observe local regulations.
Motor protection switch
Make provision for an on-site motor protection switch for devices without a plug! The
minimum requirement is a thermal relay/motor protection switch with temperature
compensation, differential triggering and anti-reactivation device in accordance with
the local regulations. In case of sensitive mains, make provision for the installation on-
site of other protective equipment (e.g. overvoltage, undervoltage or phase failure re-
lay, etc.).
