3.5.2 DC Power
CAUTION:The 24 VDC and 48VDC 9145Es are only intended to be used in a
restricted access location in accordance with Articles 110-16, -17,
and -18 of the National Electric Code ANSI/NFPA 70.
NOTE: The DC Power Terminal Block is removable for ease of installation
and replacement. It is recommended the Terminal Block be removed
when connecting power to avoid accidentally crossed or shorted
power leads from damaging the 9145E or your DC Power Source.
The 9145E is shipped with a compatible DC Power terminal block. Connect DC power to the
9145E as follows (see Figure 3-11):
NOTE: The 9145E supports both Positive and Negative grounded DC Power.
The following is the recommended procedure to connect the 9145E to a DC power source. Use
18ga to 12ga wire for GND, + VDC, and - VDC connections.
1.
Unplug the terminal block from the 9145E.
2.
Turn off the DC power source or ensure the wires are disconnected from the power source.
3.
Strip about ¼” (7mm) of insulation from the wires.
4.
Observe the polarity symbols on the product.
5.
Slide the GND wire first into the clamping yoke connection in the terminal block (that is, product
safety ground green and yellow wire).
6.
Tighten the screw to a torque of 3.6 to 4.4 in-lbs maximum (0.4-0.5 Nm).
7.
Connect the + VDC and - VDC wires in similar manner.
8.
On the terminal block, measure resistance b VDC, - VDC and GND to ensure there is no
short circuit. Use screw heads as test points.
9.
Energize source, reconnect to DC power source.
10. Measure the voltage on the terminal block to ensure voltage is between the following values:
• 36 to 72VDC for 48VDC nominal
• 18 to 36VDC for 24VDC nominal
