9 Electrical installation
DANGER
Danger to life due to electric shock!
If there is an electrical accident, you must disconnect the dosing pump
from the mains as quickly as possible.
ð
Install an emergency stop switch or integrate the dosing pump into
the plant safety concept.
CAUTION
Danger of automatic start up!
The dosing pump does not have an ON/OFF switch and may start to
pump as soon as it is connected to the mains supply. This means that
dosing medium can escape. Depending on the type and haz-
ardousness of the dosing medium, this can result in damage to
property or to injury.
ð
Install an emergency stop switch or integrate the dosing pump into
the plant safety concept.
NOTICE
Damage due to wrong mains voltage
The dosing pump can be damaged if you connect it to the wrong
mains voltage.
ð
Observe the information on the mains supply that is given on the
nameplate.
NOTICE
Insufficient electromagnetic compatibility
When you connect the dosing pump to a socket without an attached
protective earth, it is not possible to guarantee the interference
radiation and interference immunity according to EMC regulations.
ð
Only connect the dosing pump to sockets with an attached
pro tective earth.
9.1 Principles
n
According to the model the dosing pump either has a 230 V AC or a
115 V AC power supply unit.
n
The electrical connection comply with local regulations.
n
The dosing pump must be plugged into a grounded power outlet.
n
To avoid dosing errors at the end of the process, the dosing pump
must be locked electrically.
n
The dosing pump must not be operated by switching the mains
voltage on or off.
n
Signal cables must not be laid parallel to high-voltage current lines or
mains cables. You must route supply and signal lines in separate
channels. An angle of 90° is required at line crossings.
