Connecting the MX5, MX10, MX40, and MX80 Routers to Power
Tools and Parts Required for MX5, MX10, MX40, and MX80 Router Grounding and Power Connections
To ground and provide power to the router, you need the following tools and parts:
Phillips (+) screwdrivers, numbers 1 and 2
2.5-mm flat-blade (–) screwdriver
Torque-controlled driver, with a maximum torque capacity of 6 lb-in., for tightening screws to terminals on each power supply on a DC-powered router
CAUTION:The maximum torque rating of the terminal screws on the DC power supply is 6 lb-in. (0.7 Nm). The terminal screws may 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 6 lb-in. or less. Ensure that the driver is undamaged and properly calibrated and that you have been trained in its use. You may wish to use a driver that is designed to prevent overtorque when the preset torque level is achieved.

Grounding MX5, MX10, MX40, and MX80 Routers
You ground the router by connecting a grounding cable to earth ground and then attaching it to the chassis grounding points using two SAE 10-32 screws. You must provide the grounding cables (the cable lugs are supplied with the router). For grounding cable specifications, see MX5, MX10, MX40, and MX80 Router Grounding Specifications. To ground the router:
- Verify that a licensed electrician has attached the cable lug provided with the router to the grounding cable.
- Attach an ESD grounding strap to your bare wrist, and connect the other end of the strap to an approved site ESD grounding point. See the instructions for your site.
- Ensure that all grounding surfaces are clean and brought to a bright finish before grounding connections are made.
- Connect the grounding cable to a proper earth ground.
- Detach the ESD grounding strap from the site ESD grounding point.
- Attach an ESD grounding strap to your bare wrist, and connect the other end of the strap to an ESD grounding point.
- Place the grounding cable lug over the grounding points on the upper rear of the chassis (see Figure 1).
- Secure the grounding cable lug with the screws. The holes are sized for SAE 10-32 screws.
- Dress the grounding cable, and verify that it does not touch or block access to router components, and that it does not drape where people could trip on it.

Connecting Power to an AC-Powered MX5, MX10, MX40, and MX80 Router
Do not mix AC and DC power supply modules within the same router. Damage to the router might occur.
You connect AC power to the router by attaching power cords from the AC power sources to the AC appliance inlets located on the power supplies.
To connect the AC power cords to the router for each power supply:

Connecting Power to a DC-Powered MX5, MX10, MX40, and MX80 Router
Do not mix AC and DC power supply modules within the same router. Damage to the router might occur.
Before performing DC power procedures, ensure that power is removed from the DC circuit. To ensure that all power is off, locate the circuit breaker on the panel board that services the DC circuit, switch the circuit breaker to the off position, and tape the switch handle of the circuit breaker in the off position.
You connect DC power to the router by attaching power cables from the external DC power sources to the terminal on the power supply faceplate. You must provide the power cables (the cable lugs are supplied with the router). For power cable specifications, see DC Power Cable Specifications for MX5, MX10, MX40, and MX80 Routers.
