6.1.2.2 Connection to the pan & tilt
The electric connections between the
solenoid valve and P&T must be housed
in an explosion-proof junction box.
The explosion-proof junction box must
be suitable for the classification of the
explosive atmosphere in the installation
site, according to the regulations in force.
Use the RL2 (J3) internal relay to connect to the pan &
tilt, if necessary.
