Connect the DC Power
The 1200P computers with an integrated 24V DC power supply
support these electrical ratings:
•
18 to 32V DC (24V DC nominal)
•
6.3 A at 24V DC
The power supply is internally protected against reverse polarity.
To connect DC power follow these steps.
1. Secure the DC power wires to the terminal block screws.
2. Secure the ground wire to the GND terminal block screw.
3. Apply 24V DC power to the computer.
ATTENTION
Use a Class 2/SELV (Safety Extra-Low Voltage) isolated and
ungrounded power supply as input power to the computer. This
power source provides protection so that under normal and
single fault conditions, the voltage between the conductors and
Functional Earth/Protective Earth does not exceed a safe value.
V- V+
V- (DC negative)
V+ (DC positive)
GND (safety ground alternate connection)
GND (safety ground)
ATTENTION
Connect the product to earth ground using a 1.31 mm
2
(16 AWG) or larger external wire.
The ground wire should have green insulation with a yellow
stripe for easy identification.
