5.6 - Power cable entry

The power cables can enter the 30XQ control box from bottom, side or front of the unit.
For 30XQ unit sizes 0430 to 1502 the control box that includes the power supply cable connection terminal is located in
the lower part of the unit. In this case the control box is raised by 120 mm compared to the lowest point of the chassis.
The cable entry point depends on the unit configuration:
1. Unit raised from the ground (e.g. installation on support rails): It is recommended to enter the power cables from
below the control box. A removable metal plate below the control box allows introduction of the cables.
2. Unit placed on the ground: For power cable entry from below the control box ensure that the cable bend radius is
compatible with the connection space available in the control box. If not, a plate on the control box face allows
introduction of the cables.
IMPORTANT: Check the cable bend radius for cable entry into a control box, located in the lower part of the unit.
Refer to the certified dimensional drawing for the unit.
