Chapter 2 RUGGEDCOM RS401 Installing the Device Installation Guide • Section 2.2.2, “Connecting DC Power” Section 2.2.1 Connecting AC Power To connect a high AC power supply to the device, do the following: CAUTION! Electrical hazard – risk of damage to equipment. Before testing the dielectric strength (HIPOT) in the field, remove the braided ground cable connected to the surge ground terminal and chassis ground.
RUGGEDCOM RS401 Chapter 2 Installation Guide Installing the Device This cable connects transient suppression circuitry to chassis ground and must be removed in order to avoid damage to transient suppression circuitry during testing. Connect the positive wire from the power source to the positive/hot (+/H) terminal on the terminal block.
Chapter 2 RUGGEDCOM RS401 Installing the Device Installation Guide Figure 6: Failsafe Alarm Relay Wiring 1. Normally Open 2. Common 3. Normally Closed Section 2.4 Grounding the Device The RS401 chassis ground terminal uses a #6-32 screw. It is recommended to terminate the ground connection with a #6 ring lug and torque it to 1.7 N·m (15 lbf·in).
Installation Guide Installing the Device Siemens also does not recommend using copper Ethernet ports to interface with devices in the field across distances that could produce high levels of ground potential rise (i.e. greater than 2500 V), during line-to-ground fault conditions.
