3-1
Chapter 3,
Power Supply
• The controller requires an external 12- or 24-VDC power supply.
• The converter requires an external 24-VDC power supply
• The permissible input voltage range is 10.2 - 28.8 VDC, with less
than 10% ripple.
• An external circuit protection device (FIGURE 3-1) must be used.
•
A non-isolated power supply can be used, provided that a 0 V signal
is connected to the chassis.
Safety Considerations
Do not touch live wires.
Standard safety considerations require that metal cabinet
panels be earthed to avoid electrocution.
Do not connect either the 'Neutral' or 'Line' signal of the
110/220 VAC to the device’s 0V pin.
In the event of voltage fluctuations or non-conformity to
voltage power supply specifications, connect the device to
a regulated power supply.
A technician or engineer trained in the local and national
electrical standards must perform all tasks associated with
the electrical wiring of the device.
Double-check all wiring before turning ON the power supply.
FAILURE TO FOLLOW THE ABOVE CAN RESULT IN SERI-
OUS PERSONAL INJURY OR LOSS OF LIFE.
Wiring the Power Supply
• Do not use tin, solder, or any other substance on the stripped wire
that might cause the wire strand to break.
• Install unit at maximum distance from high-voltage cables and
power equipment.
• To avoid damaging the wire, do not exceed a maximum torque of
0.5 N•m (5 kgf•m).
• Use crimp terminals for wiring.
• Use 26-14 AWG wire for all wiring purposes.
