Operating Personal; Electrical Work; Electrical Connection; Ground Connection - Homa HBP 501 Manuel D'instructions Original

It is of vital importance that the system is shut down im-
mediately by the operator if any problems arise which
may endanger safety of personnel. Problems of this kind
include:
• Failure of the safety and/or control devices
• Damage to critical parts
• Damage to electric installations, cables and insulati-
on.
• Tools and other objects should be kept in a place re-
served for them so that they can be found quickly.
• Sufficient ventilation must be provided in enclosed
rooms.
• When welding or working with electronic devices,
ensure that there is no danger of explosion.
• To prevent suffocation and poisoning caused by veno-
mous gases, make sure that enough oxygen exists at
the workplace.
• Immediately after repair or maintenance work, all saf-
ety and protection equipment must be reinstalled and
placed in function again.
• All other rules and regulations and local codes co-
vering health and safety must be observed. In accor-
dance with product liability law, we point out that we
shall not be liable for damages caused by the pump
due to non-observance of the instructions and guide-
lines set forth in the operating instructions. The same
product liability are valid for accessories.
These instructions must be strictly observed.
Non-observance can result in injury or serious da-
mage to property.

2.4. Operating personal

All personnel who work on or with the product must be
qualified for such work; electrical work, for example may
only be carried out by a qualified electrician. The entire
personnel must be of age.
Operating and maintenance personnel must also work ac-
cording to local accident prevention regulations.
It must be ensured that personnel have read and under-
stood the instructions in this operating and maintenance
handbook; if necessary this manual must be ordered from
the manufacturer in the required language.

2.5. Electrical work

Our electrical products are operated with single-phase or
three-phase-current. The local regulations (e.g. VDE 0100)
must be adhered to. The "Electrical connection" data
sheet must be observed when connecting the product.
The technical specifications must be strictly adhered to.
If the machine has been switched off by a protective
device, it must not be switched on again until the error
has been corrected.
Beware of electrical current!
Incorrectly performed electrical work can result in
fatal injury! This work may only be carried out by a
qualified electrician.

Beware of damp!
Moisture penetrating cables can damage them and
render them useless. Furthermore, water can penet-
rate into the terminal compartment or motor and cau-
se damage to the terminals or the winding.
Never immerse cable ends in the pumped fluid or
other liquids.

2.5.1. Electrical connection

When the machine is connected to the electrical control
panel, especially when electronic devices such as soft
startup control or frequency drives are used, the relay
manufacturer's specifications must be followed in order
to conform to EMC. Special separate shielding measu-
res e.g. special cables may be necessary for the power
supply and control cables.
The connections may only be made if the relays meet the
harmonized EU standards. Mobile radio equipment may
cause malfunctions.

2.5.2. Ground connection

Our products (machine including protective devices and
operating position, auxiliary hoisting gear) must always be
grounded. If there is a possibility that people can come
into contact with the machine and the pumped liquid (e.g.
at construction sites), the grounded connection must be
additionally equipped with a fault current protection de-
vice.

2.6. Operating procedure

When operating the product, always follow the locally
applicable laws and regulations for work safety, accident
prevention and handling electrical machinery. To help to
ensure safe working practice, the responsibilities of em-
ployees should be clearly set out by the owner. All per-
sonnel are responsible for ensuring that regulations are
observed. Certain parts such as the rotor and propeller
rotate during operation in order to pump the fluid. Certain
materials can cause very sharp edges on these parts.
Beware of rotating parts!
The moving parts can crush and sever limbs. Never
reach into the pump unit or the moving parts during
operation. Switch off the machine and let the moving
parts come to a rest before maintenance or repair
work!

2.7. Safety and control devices

Our products are equipped with various safety and cont-
rol devices. These devices must never be dismantled or
disabled.
Equipment must be checked by an electrician for proper
functioning before start-up (see the "Electrical Connecti-
on" data sheet).
Please remember that certain equipment requires a de-
coder device or relay to function properly. This decoder
can be obtained from the manufacturer or a specialist
electronics dealer.
Personnel must be informed of the installations used and
how they work.
