This depends on whether the power supply is integrated into the main cable or connected separately. If the power supply is integrated into the main cable, the remaining cable glands can be fitted with a plug. Unused cable entries must be closed using an Ex d - proof blind plug (see Accessories). The cable gland options are suitable for cables ranging from Ø 6,5 mm to Ø 20,5 mm. Pin assignments for the 8-pin terminal block are shown below. The connection cap can easily be opened by removing the six screws in the cap. Rev. 1.2 05. November - 2015 Scancon Huginsvej 8 3400 Hillerød Denmark p. 2
