General precautions
ELECTRICAL HAZARD
Ÿ
A certified electrician must supervise all electrical work. Comply with all local codes and regulations.
Ÿ
Before starting to work on the unit, make sure that the unit and the control panel are isolated from the
power supply and cannot be energized. This applies to the control circuit as well.
Ÿ
Leakage into the electrical parts can cause damaged equipment or a blown fuse. Keep the end of the
motor cable above the liquid level.
Ÿ
Make sure that all unused conductors are insulated.
Ÿ
There is a risk of electrical shock or explosion if the electrical connections are not correctly carried out or
if there is fault or damage on the product.
WARNING
Do not install the starter equipment in an explosive zone unless it is explosion proof rated.
Requirements
These general requirements apply for a electrical installation:
Ÿ
The main voltage and frequency values must agree with the specifications on the data plate.
Ÿ
The fuses and circuit breakers must have the proper rating, and the pump overload protection (motor protection
breaker) must be connected and set to the rated current according to the data plate and if applicable the cable chart.
The starting current in direct-on-line start can be up to six times higher than the rated current.
Ÿ
The fuse rating and the cables must be in accordance with the local rules and regulations.
Ÿ
If intermittent operation is prescribed, then the pump must be provided with monitoring equipment supporting
such operation.
