Installing a power module
CAUTION:
•
Do not install AC power modules and DC power modules on the same gateway.
• Select power modules according to the power supply at the installation site.
• Provide a circuit breaker for each power module and make sure the circuit breaker is off before installing
the power module.
Some power module slots do not have a blank filler panel. The figures in this section are for illustration
only.
An AC power module and a DC power module are installed in the same way. This section uses an AC
power module as an example.
To install the power module:
1. Use a Phillips screwdriver to loosen the captive screws on the blank filler panel (if any) to remove
the blank filler panel.
2. Follow the installation graph printed on the blank filler panel of the power module to install the
power module in a correct direction:
a. Grasp the handle of the module with one hand and support the module bottom with the other.
b. Push the power module along the guide rails into the slot until it has firm contact with the slot.
For vertical slot installation, see
Figure 18 . For horizontal slot installation, see Figure 19 .
3. Press the handle inward until the handle seats into the slot.
4. Use a Phillips screwdriver to fasten the captive screw on the handle to attach the power module.
