Never solder on cable lugs or sockets as the wire strands near the solder point can break under vibration Feed the cables into the terminal box and connect as shown in the circuit diagram above See page 14 Except HV 0 4 and HV 0 8 These are connected to a European style terminal strip When tightening the cable gland cap nut en sure that the cable sheath is still fully covered by the seal If not the cable will not be secu rely fixed in place will not be strain relieved and will not be watertight 13 Re close the terminal box with seal and screw The power input must be checked during the locking device initial startup If this is larger than the value given on the nameplate this can be remedied The motor connection cable must be laid fixed by lowering the centrifugal force for approx 0 5m after it exits from the motor See Chapter 7 The first fixing point of the cable and the motor must not be able to move against each other The cable must be checked occasionally for during operation The connection cable must be chafing and if necessary the cause must be laid so that natural oscillations are avoided and removed there is no tensile loading of the cable Hexagon nut DIN EN ISO 4032 lock washer DIN 6737 DIN 7980 Brass shim Messing DIN EN ISO 7090 Terminal board bolt Cable lug DIN 46237 Maximum tightening torque terminal board nuts M4 M5 1 2 Nm 2 0 Nm 14 T Centrifuga

This means a rotating body whose weight asynchronous motor is not distributed rotationally symmetrical or dynamically balanced and therefore causes The exception is the type HV 2 GL which has vibrations The size of these vibrations can be a direct current motor as a drive controlled by weights and counterweights In the sizes HV 1 and HV 2 the stator is cast under vacuum and therefore forms an assem bly permanently connected to the housing On both shaft ends of the motor there are eccentric unbalance plates 1 Protective cover 5 Cable gland 9 Terminal board 2 Armature 6 Terminal box cover 10 Unbalance plates 3 Stator 7 Bearing end shield 11 Terminal box seal 4 Housing 8 Rolling bearing 5 Transport and Storage When they are delivered the motors must be checked for visible transport damage If the motor is visibly damaged it must not be started up The vibratory motor must be examined and if necessary returned to the manufacturer for repair Until they are installed the electric vibrators should be stored in enclosed dry rooms at a max ambient temperature of 40 C Vibrator motors must always be stood on their bases or footings Do not stack vibrator motors A The eyebolt of the size HV 55 and larger motors is solely intended for lifting the vibration motor Do not lift up the motor by its installed connection cable Note and follow the local accident prevention regulations 10 6 I
