32、ol intended for compacting concrete. The active part (vibrator bottle) of the vibrator performs low-amplitude vibrations and is immersed into the mass of concrete to be vibrated. Concrete vibrators may be of one of the following designs: a) the motor and the vibrating mechanism are inside the vibrat
33、or bottle to which the part containing the mains switch or a power converter and switch handle assembly is connected by means of a long flexible hose containing the interconnecting cable. The long flexible hose may be used as the handle (see Figure 101); b) only the vibrator mechanism is inside the
34、vibrator bottle to which a separate portable unit, comprising the motor, the handle and the mains switch, is connected by means of a long flexible hose containing a flexible shaft (see Figure 102) 14 Moisture resistance Replace the existing text of 14.1 by the following: 14.1 Replacement of the firs
35、t paragraph: For design a) as defined in 3.101, the enclosure of all parts and the cable entry shall be IPX7. During the relevant test of this subclause, the part containing the switch or the power converter and switch handle assembly is placed in the normal position of use, the hose, if any, being
36、attached correctly to it. For design b) as defined in 3.101, the motor unit shall be IPX4. During the relevant test of this subclause, the motor unit is placed in the most unfavourable position occurring during normal use. The isolating transformer or the motor-generator shall be IPX4. 18 Abnormal o
