WARNING: Before making any changes to the wiring of your Tenor CMS, turn off both circuit breakers
and open the upstream disconnect switches at the source of the DC power feeds.
NOTE: The electrical installation must comply with the National Electrical Code 1996 or other country
specific electrical installation codes.
Figure 3-8 DC Power Panel (located on bottom rear of chassis)
The top circuit breaker controls the left power inlet and the bottom circuit breaker controls the right power
inlet. See Figure 3-8. Each circuit breaker has a dual colored rocker. Pushing down on the left side of the
breaker (ON/1) will close the switch and expose a red indicator that shows the user that the contacts are made
(closed). To open the contacts, push down on the right side (Off/O).
1. Check to ensure the source of both DC feeds to the CMS are turned off and the circuit breakers are in the
off position prior to making or removing any power wire connections.
2. Beginning with the wire attached to Earth Ground, strip away 0.25 in. (7.0 mm) of insulation. See Figure
3-9.
