7. ELECTRICAL INSTALLATION
All electrical connections must be performed by AUTHORIZED AND QUALIFIED personnel only.
Before to proceed, please, verify the following steps:
- verify that pump’s label values are compatible with main power supply.
- pump must be connected to a plant with a differential switch (0,03A
sensitivity) if there isn’t a good ground.
- to avoid damages to the pump do not install it in parallel with heavy
inductance load (for example: engines). A relay switch must be used. See
below picture.
P - Dosing Pump
R - Relay
I - Switch or safety device
E - Electrovalve or inductance load
A - Main Power
WARNING
IF EQUIPMENT IS NOT SUPPLIED WITH A PLUG:
a) a switch or circuit-breaker shall be included in the building installation
b) it shall be in close proximity to the equipment and within easy reach of the operator
c) it shall be marked as the disconnetting device for the equipment
WARNING
IF EQUIPMENT IS SUPPLIED WITH A PLUG:
If an appliance coupler or separable plug is used as the disconnecting device, it shall be readily identifiable
and easily reached by the operator. For single-phase portable equipment, a plug on a cord of length not
greater than 3m is considered to be easily reached.
