Work
•
Be sure to provide explosion-proof wiring if the product is to be used in hazardous places.
Cable Work
•
Use a shielded cable, such as CVV-S with a thickness of 1.25 to 2.00 mm
2
. Lay all cables
in protective tubes, such as metal conduits or carbon steel pipes, or other protective
structure, such as a concrete duct.
•
When using the external contact function of the product, which requires a five-conductor
cable, make sure that the maximum diameter of the cable conductor is 1.25 mm
2
. When
using only the analog signal function, which requires a three-conductor cable, without the
external contact function, make sure that the maximum diameter of the cable conductor is
2.00 mm
2
.
•
When using the explosion-proof packing lead-in method, refer to the following table and
use a cable with the finished diameter matching the inner diameter of the packing. In order
to prevent the spread of explosive gas or fire, securely tighten the cable gland.
•
It is recommended not to connect two cables together. If it is unavoidable, however,
connect them or branch them within the explosion-proof casing of the main unit.

* A pressure-tight packing with a diameter of 12.5 mm, a washer with a diameter of
12 mm, and a B clamp, all of which correspond to a cable with a diameter of 11.5
mm, are built into the standard model.
* Three pressure-resistant packings with diameters of 12 mm, 13 mm, and 13.5 mm,
two washers with a diameter of 11 mm, two washers with a diameter of 14 mm, one
A clamp, and one C clamp are provided with the standard model. These correspond
to cables with diameters of 11 and 12 mm.
* If the cable diameter is other than 10.5 or 12.5 mm, select the corresponding
pressure-resistant packing, washer, and clamp from the above table, and order
them from New Cosmos.
