6. CDM COMMISSIONING GUIDANCE
• Do not use mobile phones or radio communication equipment within 2 metres (6 feet) of the enclosure.
• Connect this equipment to earth (ground) using the earth terminal provided.
The minimum size of the protective conductor must be in accordance with local safety regulations.
• High Leakage Current
This equipment and the driven motor(s) must be earthed (grounded).
• This equipment may be connected to more than one live circuit.
Disconnect all supplies before working on the equipment.
• High Voltages
Replace all shrouds and close all doors before energising the equipment.
• Wait at least eight minutes after isolating supplies and check that the voltage between DC+ and DC- has
reduced to a safe level before working on this equipment.
• Surfaces on the following items can reach high temperatures and remain hot for some time after power has
been removed:
- reactors & transformers
- cables
• The combined audible noise emitted by fans in an installation can be greater than 70 dB(A), dependent on
the air flow path.
- Measure the audible noise in the installation.
- When the audible noise level exceeds 70 dB(A), appropriate warning notices should be displayed.
• This equipment contains solid state devices which may be affected by electrostatic discharge.
Observe static handling precautions.
• Ensure that all conductors connected to this product are mechanically restrained.
• Where nuts, bolts and washers are supplied fitted to the terminal busbar, remove these fasteners, place the
user’s crimp (or busbar) directly against the terminal busbar of the unit and refit the fasteners. This is to
prevent large currents flowing through steel fasteners and causing overheating.
6.1 INTRODUCTION
The detailed commissioning procedure for an Air Cooled DELTA Drive System will vary for each application;
such details are not included in this manual. However, reference should be made to the MV3000e Getting
Started Manual T1676 (or T2002 for AEM drives) which does include general guidance for commissioning. The
procedures in this manual are split into two discrete sections. This section describes the commissioning
procedures for the Complete Drive Module that should be undertaken by the enclosure manufacturer.
Section 7: PDS Commissioning Guidance describes the procedures for integrating the CDM into the end user’s
application.
Each section gives guidance on visual inspection, coolant system pressure tests and electrical safety tests.
When the equipment has been designed and built for a particular application by an enclosure manufacturer
then it is important, for the safety of personnel and equipment, that all commissioning instructions prepared
by the manufacturer include the following details:
• Warnings and cautions as necessary;
• Visual / mechanical checks;
• Electrical safety checks;
• Cooling system checks - internal and external to the enclosure;
• Functional tests.
