INTELLIGENT ACTUATOR
(1) Environment
Use your X-SEL-P/Q controller in an environment conforming to pollution degree 2 or 1 as specified
in IEC 60664-1.
Example) Install the controller in a control panel having a structure resistant to intrusion of water,
oil, carbon, dust, etc (IP54).
(2) Power Source
A) Use the controller in an environment conforming to overvoltage category II as specified in IEC
60664-1. To meet this requirement, be sure to install a circuit breaker between the distribution
board and the X-SEL controller.
B) If the I/O power or electromagnetic brake power is supplied externally, use a 24-VDC power
supply bearing a CE Mark.
(3) Grounding
To prevent electric shock, be sure to connect the FG terminal of the X-SEL-P/Q controller and the
protective grounding terminal (grounding plate) of the control panel.
(4) Earth Leakage Breaker
Install an earth leakage breaker (residual current device, or RCD) on the primary side of the X-SEL-
P/Q controller.
