SPECK Pumpen IN-VB-S 15-150 F [69/100] Electrical connection

Installation

11|2018 EN 19

2. Connect the pipe free of tension according to the VDMA standard sheet 24277. Use compensators.

3. Always connect the pump to the pipework using counter flanges.

4. Ensure that any leaks cannot cause consequential damage. Install a suitable retainer if necessary.

WARNING

Pumped fluid hazardous to health!

 Observe legal regulations regarding the disposal of media hazardous to health.

5.4 Electrical connection

WARNING

Risk of electric shock due to incorrect connections!

 Electrical connections must always be carried out by authorised specialists.

 Observe VDE and utility company regulations.

 Install pumps for swimming pools and their protection according to DIN VDE 0100-702.

 Check pipework for damage and replace if necessary. Never attach damaged pipework.

 Install a disconnecting device with at least a 3 mm contact gap per pole to interrupt the power supply.

WARNING

Risk of electric shock due to voltage on the housing!

 A correctly set motor protection switch must be installed for pumps with single and three-phase

motors. In doing so observe the values on the motor’s name plate.

 Protect power supply with a ground fault circuit interrupter, nominal residual current I

≤ 30 mA

(higher current class if necessary when other devices are being run at the same time – always

according to the local regulations).

 Only use suitable pipe types according to regional regulations.

 Adjust minimum diameter of the electrical pipes to accommodate the motor output and pipe length.

 Do not bend or squash the pipes.

 If hazardous situations can occur, provide an emergency off switch according to DIN EN 809. The

builder/operator must make a decision according to this standard.

 If the pump is used in fire protection equipment, automatic switch off via a motor protection unit may

not occur.

5.5 Check the direction of rotation

NOTICE

 Ensure that the pump/unit is full of water.

NOTICE

The pump/unit is louder and pumps less when the direction of rotation is incorrect.

• Correct direction of rotation: clockwise, when looking at the motor from the fan.

• The arrow showing the direction of rotation can be found on the drive lantern.

1. Turn the motor on and immediately off again.

2. Check the direction of rotation. Correct the direction of rotation where necessary.
