Mobile hoisting gear: Installing a cable bollard
Fig. 11:
Lifting equipment secured to a cable
bollard
If a mobile hoisting gear is used, install a cable bollard at the edge of the basin:
•
Remove lifting equipment (e.g. wire rope) from the hoisting gear and secure to the cable
bollard.
•
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 potential
abrasion. Sharp edges may damage the connection cable. Bevel the basin edge if neces-
sary!

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 explosion!
• 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.
•
Power supply on mains side with clockwise rotating field for three-phase AC motors (3~
motor).
•
Route the connection cables according to the local regulations and connect them ac-
cording to the wire assignment.
•
Connect
all
of the monitoring devices and check their function.
•
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 min-
imum requirement is a thermal relay/motor protection switch with temperature compensa-
tion, differential triggering and anti-reactivation device in accordance with the local regu-
lations. In case of sensitive mains, make provision for the installation on-site of other pro-
tective equipment (e.g. overvoltage, undervoltage or phase failure relay, etc.).
Residual-current device (RCD)
•
Install a residual-current device (RCD) in accordance with the regulations of the local
energy supply company.
