1.15 Cooling
The circuit breaker panel is well ventilated to allow efficient convection cooling of all components
without the use of fans or blowers. Holes are provided in the top and bottom of the panel to allow
heated air to escape from the panel and cool air to enter.
1.16 Protective Cover
A thick plastic protective cover is mounted over the input power connectors, the output power
connectors, the chassis ground terminals, and the external alarm contact connections. Access to
these connectors and terminals is obtained by removing the cover. The cover is easily removed
by loosening (but not removing) four screws that attach the cover to the chassis. The holes in the
cover are keyed to allow it to be pulled to the side and then lifted clear of the screws.
