After unpacking the pump, carry out the following check points:
Delivery Check
Check for possible transport damage and especially check that the cable has not
been nicked or damaged.
Check for complete delivery.
When the delivery is incomplete or damaged, please contact your dealer
immediately.
Oil Level
Check the oil level (see Routine Maintenance section: Oil Level).
Power Supply
Before making the electrical connections, check if the line voltage and frequency are the
same as on the pump data plate.
For examples of electrical diagrams and pump cable coding, see appendix 1.
Cable Entry
Especially when the pump has been in storage for a long time, the cable gland should be
checked and if necessary tightened.
Motor Protection
The pump should always be connected to the line by means of a suitable motor protection
circuit breaker.
Overload protection must be provided in the panel.
Motor Check
If in doubt about the condition of the motor or cable, Megger test motor windings against
grounding wire.
The phase resistance against grounding wire should be at least 1 Mohm.
