6.3 Terminal boxes Frame size 132–160: The terminal box of the motor is located on top of the motor frame. The terminal boxes of motors with frame size 80 to 355 are de- signed with six terminals suitable for the various voltage options defined in the associated certificates. A steel or copper electroplat- ed stud for earthing is present inside the terminal box. Before working on the motor or attached machinery: • Ensure that all supply voltages are switched off and locked out. • Switch off auxiliary power circuits for accessories such as anti- condensation heaters. • Check the supply voltage and frequency by comparing them Frame size 180–225: with the rated data on the nameplate and the data sheet. • Ensure that the terminal box is clean and dry. • Ensure that the flame path of the terminal box is intact and free of any form of damage. - Page 18 Terminal box for CAR-Ex d Frame size 315: Frame size 80–112: Frame size 355: Frame size 132–160: Frame size 400: Frame size 180–200: Frame size 225–280: For motors with EAR-Ex e or CAR-Ex d terminal boxes, ensure strict compliance with the clearances specified in EN IEC 60079-7 between all enclosure components, the flameproof joint and bare conductors inside the terminal box, bare conductors and the metal enclosure (see Table 4).

Page 20: Special Condition For Use Fs 400
If the ambient temperature is above 40°C but does not exceed 60°C, the temperature values in the table above must be increased accord- ing to the difference between 40°C and the actual temperature. Example: With frame size 112 and Tamb = 55°C, the maximum rated operating temperature of the cable must be (55 – 40) = 15 + 56 = 71°C If the motor has direct cable entry (flying leads), the free end of the cable leading to the motor must be connected according to the regu- lations applicable to the connection range. If the cable entry fitting on the motor has a strain relief, the cable can be routed freely; otherwise the cable must be secured near the motor to provide strain relief. The maximum operating temperature of the cable must not be exceeded. 6.5.1 Special condition for use FS 400 Suitable heat-resisting cables must be applied for mains supply and for auxiliary connections. 6.6 Sealing gasket The sealing ring is made from rubber XH - 21, the mechanism phys- ical property of which conforms to GB/T7594.9. The material of sealing gasket should pass the tests for endurance top heat and to cold according to 26.8 and 26.9 of GB 3836.1-2010. If tolerance is not indicated, the limit deviation value will be that GB/T1804 - m. The sealing ring is made of rubber Shore-hardness 45-55o.
