Motors with terminal boxes whose mains lead is located in the layer
separating the upper and lower parts
Use only the supplied original gaskets to ensure compliance with the “Ex e
II” degree of protection. Depending on the type (see marking on the plug),
the plugs are fit for the following diameters (
ÎTable 5).
Follow carefully the operating instructions for the lead-in parts and sealing
plugs.
Table 5: Cable diameter
Type
Cable diameter
RS-75
26 to 48 mm
RS-100 48 to 70 mm
> After connecting the mains lead close the terminal box with the upper
part.
> Strip the skins of the plugs so that the following condition is fulfilled:
By stripping the skin, the plugs are adapted to the cable diameter so
that a gap of less than 1 mm is obtained between the cable and the
plug applied on the cable.
Therefore, an extra layer of skin must be removed from one half of the
module compared to other.
> Lubricate the cutting edge and the sealing surfaces of the plug with the
supplied grease.
> Insert the plug halves over the cable and completely in the bushing
opening.
> Brace it with the screws until a perceivable resistance (maximum
torque: 6 Nm) is achieved.
