Mitsubishi Electric FR-LU08 Instruction Manual page 4

Caution
Waterproof and dustproof performances of FR-LU08-01
 When securely fixed to the inverter with screws, the operation panel (FR-LU08-01) is rated IPX5
 The items enclosed with the FR-LU08-01 such as the Instruction Manual are not rated with the IPX5 waterproof or IP5X dustproof ratings.
 Although the FR-LU08-01 (except for the connector) is rated with the IPX5 waterproof and IP5X dustproof ratings, it is not intended for use in water.
Also, the ratings do not guarantee protection of the FR-LU08-01 from needless submersion in water or being washed under strong running water such as a shower.
 Do not pour or apply the following liquids over the FR-LU08-01: water containing soap, detergent, or bath additives; sea water; swimming pool water; warm water;
boiling water; etc.
 The FR-LU08-01 is intended for indoor
snow, or freezing temperatures.
 If the screws of the FR-LU08-01 are not tightened, or if the FR-LU08-01 is damaged or deformed, the IPX5 waterproof performance and the IP5X dustproof
performance are impaired. If any abnormalities are found on the FR-LU08-01, ask for an inspection and repair.
 To maintain the waterproof and dustproof performances of the FR-LU08-01, daily and periodic inspections are recommended regardless of the presence or
absence of abnormalities.
