C3.1 - TERMINAL BOX Placed as standard on the top of the motor near the drive end, the terminal box is made up of IP 55 components and is fitted with a cable gland in accordance with the table below. The standard position of the cable gland is on the right, seen from the drive end but, owing to the symmetrical construction of the box, it can usually be placed in any of the 4 directions, except for: - position 2 for flange-mounted motors. - positions 2 and 4 for PLS 315 MG/LG/ VLG/VLGU, PLS 355 and PLS 400 motors. If required, the terminal box may be fitted in a different position (on the left or right as seen from the drive end).
