7. Motor Connections
To mains:
7.1. Connection of the electric motor to the mains supply should be made by a qualified person. The current
rating of the motor will be identified on the motor plate, and correct sizing of the cables to electrical
regulations is essential.
Motor terminal connection:
7.2. The motor should be wired in accordance with the manufacturers instructions.
8. Starting Up
8.1. Prior to Starting Up
8.1.1. Ensure all operational safety devices are in place (i.e. guards fitted). Check and adjust guards and
covers so that there is no ignition source from sparks that may be thrown by moving parts making
contact with guards etc. Ensure coupling guards, covers etc are dust tight or are designed in such a
way that a build up of dust deposits cannot form when the unit is used in Zone 21 & Zone 22
classification areas.
8.1.2. Check the pump unit has been assembled correctly for the required direction flow and shaft rotation.
8.1.3. Remove any temporary safety devices/locks fitted to prevent personal injury during assembly.
8.1.4. Starting up should only be performed or supervised by suitably qualified personnel.
Caution: Any deviation from normal operating conditions, (increased temperature, noise,
Vibrations, power consumption etc) suggest a malfunction, inform maintenance personnel
immediately.
9. Operation
9.1. Noise
Check the noise level of the pump and surrounding equipment
Ear protection should be worn when working in close proximity of the pump when the noise level
exceeds 85db(A)
9.2. General Safety
Potential hazards which can be encountered during installation, maintenance and operation of pump
units is covered in greater detail in the product safety page at the front of this booklet.
Advice is also given on sensible precautions which need to be taken to avoid injury or damage.
PLEASE READ!
9.3. Pump Units for Use in a Potentially Explosive Atmosphere
After 1 hour of operation check the pump surface temperature. The temperature should not exceed
the values shown in the table below, If the temperature exceeds this limit, shut down immediately and
contact our application engineers
