Mounting notes:
• For the power connector, one-wire cables and stranded cables can be used with or without wire
end ferrule (acc. to DIN 46228). These wire end ferrules can be with or without plastic collar. The
contact surface has to be 8 mm.
• The cable cross-section allowed is between 0.75 and 1.5 mm
2
(AWG 19 to AWG 16) for ctrlX CORE
X2 and ctrlX CORE X3.
•
The cable cross-section allowed is 1.5 mm
2
(AWG to 16) for the ctrlX CORE
PLUS
.
• Use only cables approved for temperatures of at least 60°C.
• Use freely routed 1-wire cables. The wire distance has to be at least the wire diameter.
• The stripping length is 8 mm.
•
To use stranded cables without wire end ferrules, twist the strand between 180° and 360°. The
stripped area has to be 8 mm after twisting. If stranded cables are introduced, keep the pushbutton
of the push-in terminal pressed.
• To remove the cables, press the pushbutton of the push-in terminal.
Positioning the power connector
1. Position the connector on the connector holder.
2. Engage the connector on top.
