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.
1.
Connect the positive wire from the power source to the positive/hot (+/L) terminal on the terminal block.
Figure 6: Terminal Block Wiring
1. Positive/Hot (+/L) Terminal
2.
Connect the negative wire from the power source to the negative/neutral (-/N) on the terminal block.
3.
Using a braided wire or other appropriate grounding wire, connect the surge ground terminal to the chassis
ground connection. The surge ground terminal is used as the ground conductor for all surge and transient
suppression circuitry internal to the unit.
4.
Connect the ground terminal on the power source to the chassis ground terminal on the device. For more
information, refer to
Section 2.3
Connecting the Failsafe Alarm Relay
The failsafe relay can be configured to latch based on alarm conditions. The NO (Normally Open) contact is
closed when the unit is powered and there are no active alarms. If the device is not powered or if an active alarm
is configured, the relay opens the NO contact and closes the NC (Normally Closed) contact.
NOTE
Control of the failsafe relay output is configurable through ROS . One common application for this relay
is to signal an alarm if a power failure occurs. For more information, refer to the ROS User Guide for
the RS8000.
The following shows the proper relay connections.
