4.5 The moving parts of the fan shall be protected or equipped with protective covers to protect personnel from injury. The fan housing shall be equipped with drains to prevent water accumulation in the installation position. If it is determined that the design of the moving parts of the fan is not suitable, additional protection shall be installed. 4.6 The equipment to be installed on the fan shall be protected. 2.7 The parts of the fan shall be selected so that no electrical corrosion will occur in the presence of seawater: 4.8 The parts of the fan shall be able to withstand the pressure of seawater. 4.9 Each fan shall be equipped with a fan performance cable installation manual (6.2). 5 Electrical requirements
5.1 The fan shall be a two-wire type. The cable and the return cable shall be insulated from the motor. 5.2 The conductor used for the connection shall be a relatively long cable. Note: The requirements for low-power electrical basic quality shall be determined in the original standard. 53 If there is an external effective wiring strap, the test terminal shall be designed to be a natural contact element between the two main power components.
5.4 The fan has an external motor cable. The specification of these cables shall meet the requirements of the transmission power. The nominal cable shall not be less than 1m. The insulation of the wire is suitable for use in the environment of 20% nominal current and eC.
5.5 The following measures should be taken to prevent the fan from continuing to be in a rotor stuck state out of specification: Overall overcurrent protection
: The value of the protection should be within the rated value to ensure that the fan is in a motorized state; Overcurrent protection: - The maximum speed at which the fan rotates must not exceed 151% when the ambient temperature is maintained at 75°C, and it must be especially careful to avoid combustion, burning or reverse rotation.
6 Fan Rating
6.1 Fans should be rated with electrical ratings (V) and amperes () or with rated W). 6.2 The rated ratings required should be calibrated using the following methods given in the relevant standards. Before calibration, some national standards are required. The 1S80 standard is combined with these standards. 6.2.1 Fans with discrete air inlets and outlets (class B are mostly the following standard screens); AMCA210.1985/ASHRAE5185.
