Special Installation (Ceiling-suspension (with wires))
3.4.4 Ceiling-suspension (with wires)
When suspending from ceilings, attach the unit either at rows A and B or at rows C and D to keep it free of deforming
forces. In addition, the unit must be fastened at more than four points, with these points distributed symmetrically on
opposite sides of the vertical and horizontal center lines.

Wires
Bracket

When suspending from a ceiling, use the brackets shown
at right to prevent concentrating loads on the upper two
fixing points.
For additional safety, secure the wires to separate fittings
or parts of the ceiling.
Use mount screws composed of material stronger than
soft steel, and use hexagonal bolts.
Use wires adequate for the combined weight of the unit
(43.0 kg) and the weight of the support brackets.
