Checks before mounting
- Perform the following checks: D = detailed check, N = close inspection, S = visual inspection
Test schedule | D | N | S | |
|---|---|---|---|---|
I | Unit corresponds to EPL/zone requirements of the installation location. | ● | ● | ● |
II | Correct device group. | ● | ● |
|
III | Correct temperature class for units. | ● | ● |
|
IV | Degree of protection (IP degree) of units corresponds to level of protection / group / conductivity. | ● | ● | ● |
V | Unit power circuit name present and correct. | ● | ● | ● |
VI | Housing and connections satisfactory. | ● | ● | ● |
VII | Before installing, check that the motor bearing is functioning properly. | ● | ● | ● |
The impeller is balanced in accordance with ISO 14694 and ISO 1940-1. The vibration level of units is checked ex factory in accordance with ISO 14694. The vibration level must be checked again at the installation site in accordance with ISO 14694 (vibration values according to category and prescribed limit values).
- Before installation, check the application category of the units and the vibration limits for on-site tests, in particular for the start-up, alarm and stop operating statuses. Run a vibration check and check the vibration values after commissioning (ISO 14694, BV-3, Veff. max. 4.5 mm/sec.). If required, install components for avoiding vibration.
- Install the command equipment needed for starting, stopping, emergency stops or resetting after an emergency stop. Undertake installations in accordance with the planning documents and relevant regulations (EN 60079-14).
- Install a function monitor with alarm function to warn persons in case of malfunctions/unit failure and to avoid damage to property.
