1. Pluggable Terminal Block for HIP Power Supplies 2. Screw-Type Terminal Block for HI Power Supplies 3. Positive/Live (+/L)
Terminal 4. Ground Terminal 5. Negative/Neutral (-/N) Terminal
2. Connect the negative wire from the power source to the neutral/negative (-/N) terminal on the terminal block.
3. Using a braided wire or other appropriate grounding wire, connect the ground terminal to the chassis ground
connection. The ground terminal is used as the ground conductor for surge and transient suppression
circuitry internal to the unit.
4. Connect the ground terminal on the power source to the ground terminal on the device. For more
information, refer to Section 2.4, “Grounding the Device”.
Section 2.2.3
Connecting Low DC Power
To connect a low DC power supply to the device, do the following:
CAUTION!
Electrical hazard – risk of damage to equipment. Do not connect AC power cables to a 12, 24 or 48
VDC power supply terminal block. Damage to the power supply may occur.
IMPORTANT!
When connecting the device to a DC power source, make sure the source provides only positive
voltage.
NOTE
The screw-type terminal block is installed using Phillips screws and compression plates, allowing either
bare wire connections or crimped terminal lugs. Use #6 size ring lugs for secure, reliable connections.
1. Connect the positive wire from the power source to the positive (+) terminal on the terminal block.
