2-1: Sealing performance of the cabinet
The method for the securement of sealing performance of the cabinet is described.
It is necessary to install the servo amplifier in the sealed type cabinet for protection
of the electronic circuit portion of the servo amplifier.
(1) Don’t make a hole and a gap where the air is drawn in. (Fig. 1)
Although an air filter closes a hole, it cannot seal completely. Therefore, don't make
a hole.
(2) Don't install a fan motor in a wall of the cabinet by making a hole. (Fig. 1)
For heat exchange with the air, use a heat exchanger or an air conditioner with the
structure that the sealing performance of a cabinet is secured.
(3) Don't make a gap to the junction of a wall and a wall. In a partial junction like spot
welding, seal by seal adhesive so that a gap is not made between junctions. (Fig. 1)
