Pre-Installation

Location

Be sure to allow sufficient space for the Long AC Conduit Box to be mounted

directly adjacent to the inverter’s AC side. Be sure to leave room for expansion if

necessary. Also consider the additional weight and ventilation space requirements

of the Long AC Conduit Box.

Service Planning

If for any reason the inverter may need service or needs to be removed from the

position where it’s mounted, the following recommendations should be

considered to make this task easier.

To make servicing the inverter easier to accomplish:

• Use flexible conduit.

• When mounting the components such as the ACCB-L or DCCB-L next to the

inverter, bias the mounting screws away from the inverter. This will allow

"sliding" room within the mounting holes, so that the ends can slide apart

without being removed from their mounted position.

Figure 2-10, “Installing the ACCB-L to the SW Plus Inverter on Plywood” on

page 2–13 for details.

WARNING: Shock Hazard

Ensure that no DC voltage is being supplied to the inverter and that no AC voltage is

present on the AC wiring. Failure to do so could cause serious injury or death. A warning

label is provided to inform all personnel that multiple sources of power are available

inside. This label should be installed on the outside cover to be clearly visible. Ensure all

sources are OFF or disconnected before servicing.
