Special Operations - Fusion in Explosive Atmosphere

6 - 2

Hydraulic Power Unit (HPU)

Electric motors are not explosion proof. Operation

of these components in an explosive atmosphere

will result in serious injury or death.

The HPU is not explosion proof and must be located outside of the

explosive atmosphere.
Locate HPU in a safe environment. Plug the electrical cord into a

proper power source.
