Connecting the ACX500 to Power

 

Connecting an AC Power Cord to the ACX500 Indoor Router

To connect AC power to the router, you need the following tools:

  • Electrostatic discharge (ESD) grounding wrist strap

  • AC power cord (not provided)

Note

Power cord for the ACX500 indoor routers are not shipped with the router. You need to purchase the power cord separately.

To connect AC power to the router:

  1. Locate the power cord, which should have a plug appropriate for your geographical location. See the ACX500 Router AC Power Cord Specifications.
  2. Wrap and fasten one end of the ESD grounding strap around your bare wrist, and connect the other end of the strap to the ESD point on the chassis.
  3. Insert the appliance coupler end of the power cord into the appliance inlet on the power supply.
  4. Insert the power cord plug into an external AC power source receptacle.Note

    We recommend that you use a dedicated customer-site circuit breaker rated for 20 A (100 VAC) or 16 A (240 VAC), or as required by local code. Doing so enables you to operate the router in any configuration without upgrading the power infrastructure.

  5. Verify that the power cord does not block the air exhaust and access to router components, or drape where people could trip on it.
  6. Observe the system LED on the router. If an AC power supply is functioning normally, the system LED lights green steadily.

    If the system LED is not lit, the power supply is not functioning normally. Repeat the cabling procedures.

Connecting DC Power Cables to the ACX500 Indoor Router

To connect DC power to the router, you need the following tools:

  • Phillips (+) screwdriver, number 2

  • Electrostatic discharge (ESD) grounding wrist strap

  • M3 screws and flat washers

  • DC power source cables, minimum 14 AWG or as required by local code (not provided)

  • Ring lugs, Molex 190700067 or equivalent (not provided)

Note

Power cables for the ACX500 indoor routers are not shipped with the routers. You need to purchase the power cord separately.

The DC power supply has four terminals on the front panel, covered by a clear plastic cover.

Warning

You must ground the router before connecting the DC power cables.

To connect the power cables:

  1. Switch off the dedicated customer-site circuit breakers. Ensure that the voltage across the DC power source cable leads is 0 V and that there is no chance that the cable leads might become active during installation.
  2. Remove the clear plastic cover protecting the terminal on the faceplate.
  3. Verify that the DC power cables are correctly labeled before making connections to the power supply. In a typical power distribution scheme where the return is connected to chassis ground at the battery plant, you can use a multimeter to verify the resistance of the DC cables to chassis ground:

    Locate the power cables, which should have a plug appropriate for your geographical location. See the ACX500 DC Power Specifications.

    For –48V and –60V:

    1. The cable with very large resistance (indicating an open circuit) to chassis ground is the DC input cable ().

    2. The cable with very low resistance (indicating a closed circuit) to chassis ground is the return cable (+).

    For +24V:

    1. The cable with very low resistance (indicating a closed circuit) to chassis ground is the return cable ().

    2. The cable with very large resistance (indicating an open circuit) to chassis ground is DC input cable (+).

  4. Remove the screws and flat washers from the terminals.
  5. Secure each power cable lug to the terminal with the flat washers and screw (see Figure 2). Apply between 8 lb-in. (0.9 Nm) and 9 lb-in. (1 Nm) of torque to each screw. Do not overtighten the screw. (Use a number 2 Phillips screwdriver.)
    1. Secure the positive DC source power cable lug to the return (+) terminal.

    2. Secure the negative DC source power cable lug to the input () terminal.

    Caution

    Ensure that each power cable lug seats flush against the surface of the terminal block as you are tightening the screws. Ensure that each screw is properly threaded into the terminal. Applying installation torque to the screw when improperly threaded might result in damage to the terminal.

    Caution

    The maximum torque rating of the terminal screws on the DC power supply is 9 lb-in. (1 Nm). The terminal screws might be damaged if excessive torque is applied. Use only a torque-controlled driver to tighten screws on the DC power supply terminals. Use an appropriately sized driver, with a maximum torque capacity of 9 lb-in. (1 Nm) or less. Ensure that the driver is undamaged and properly calibrated and that you have been trained in its use. You might want to use a driver that is designed to prevent overtorque when the preset torque level is achieved.

  6. Replace the clear plastic cover over the terminals on the faceplate.
  7. Attach an electrostatic discharge (ESD) grounding strap to your bare wrist, and connect the strap to an approved site ESD grounding point. See the instructions for your site.
  8. Connect each DC power cable to the appropriate external DC power source. Note

    For information about connecting to external DC power sources, see the instructions for your site.

  9. Switch on the external circuit breakers to provide voltage to the DC power source cable leads. Observe the system LED on the front of the router. If the DC power cable is correctly installed and functioning normally, the system LED lights green steadily. If the status LED indicates that the power supply is not functioning normally, repeat the installation and cabling procedures.
