Is it unnecessary to protect the cable if it is certified for explosion-proof ?
（Explosion-proof Motor）
Cable protection (electrical wiring) must be considered separately from explosion proof testing.
If it is certified for explosion protection, it is not necessary to protect the cable.
When incorporated into a robot, we guaranteed as a robot manufacturer by fixing it so that there is no rubbing at the movable part and by performing an endurance test.
If the product is not incorporated into a robot and is used in a dangerous area (for example, put the cable by routing), it is necessary to protect the cable from damage.
(To prevent a sharp object contacts and the cable is damaged and becoming an ignition source)
In this case, the equipment manufacturer will guarantee it.
