Safety Provisions

Read the following instructions carefully before working on the fan, and perform the work detailed in them as described. Do not perform any work which is not described in this guide.

DANGER
HAZARD OF ELECTRIC SHOCK, EXPLOSION, OR ARC FLASH Respect the LOTO procedure according to OSHA requirements. Ensure that the system is isolated from high voltage, supply voltage, and properly grounded. Ensure that the VCB is in test condition, the E/S is closed, and access is locked. Do not operate the device without a guard, as a person's hands could accidentally get trapped in the machine while it is running. Additionally, loose parts (like small tools) or loose clothing could be pulled into the device, leading to serious injury. The device is a built-in component. As the owner is responsible for ensuring that the device is adequately safeguarded. Operate the device only with a fixed protective device and guard grill. Stop the device immediately if a protective device is found missing or ineffective. Failure to follow these instructions will result in death or serious injury.
