There may be no foreign objects such as dirt, particles
or humidity inside the terminal board.
Mount terminal board cover to motor tight against dust
and humidity and close up all unused wiring ports.
ATTENTION
When Variable Frequency Drives are used interfering
signals might occur.
Non-sinus shaped supply voltage from a variable fre-
quency drive might result in elevated motor tempera-
tures.

6 Start-up / Shut-down

6.1 Start-up
ATTENTION
Switch off at the mains.
After connection the electrical wires, close the termi-
nal box. Briefly start the motor (max. 30 sec.) and
check the rotation according to the arrow on the top of
the motor.
If the direction is incorrect change over two of the
power leads.
6.2 Shut-down
All service work must be carried out by qualified service
personnel. Pump must be disconnected from the
power source and all rotating parts must stand still. Re-
assure that pump is disconnected from power source
and cannot be switched on. Verify that there is no volt-
age at the terminal board!
Open terminal box and disconnect the power leads.
Empty out the pump.

the mounting flange, also ensure that the minimal liquid
level for the STA pump is 2.36 Inches (60 mm) before
starting up the motor, for the SAL pump the suction
hole of the pump body must be covered with liquid.

If the pump should lock up and cease, shut pump
down (see 6.2) and disconnect from power supply.
Pump must be uninstalled and removed from the
system prior to its repair.
Attention! Potential Risk of Burning!
Surface temperatures above 50°C do occur during
regular operation, i.e. on the surfaces of the motor
and bearing housing.
It must be insured that the pump has cooled down
sufficiently prior to performing any repair or
maintenance work.
