6.6 Breaker installation
1. Ensure mid-trip breakers are used for load and series-trip breakers are used for battery connections.
2. Turn the breaker OFF.
3. Orient the breaker so that the actuator is down with the breaker in the OFF position.
4. Align the breaker terminals with the correct holes.
5. Carefully push the breaker into position.
6. Ensure that the breaker is fully inserted so that the flat face of the hexagonal nut is against the mounting
surface.

6.6.1 Breaker removal
1. Turn breaker off.
2. Carefully pull the breaker out of position.
NOTE
With step 4, the air circulation required is considerably less than what is normally designed into
an outdoor enclosure, therefore this should be met by standard designs. However, as cooling
performance is very specific to the mechanical implementation, it is recommended to test for
compliance under maximum load conditions (using battery discharge test).
6.5.3 Systems mounted in outdoor enclosures (operated above 40°C)
Attach the power system to the customer-provided enclosure using mounting screws and star washers to ensure
an electrical bond between system chassis and relay rack. The 19" and 23" CXPS-E3 systems may be either
flush or center mounted in the enclosure.
If the system will be operated in ambient temperatures above 40°C, the following installation steps must also be
followed:
1. The clear polycarbonate top cover must be removed, if applicable.
2. The enclosure design must prevent the operator from touching the output bus bars/lug connections.
3. The battery breakers used must be rated 100A or lower, if applicable.
4. Air circulation within the enclosure must be sufficient to maintain the breaker bullets below 105°C in all
operation conditions.
