5.0 Installation
Important! A licensed electrician is required to install the Apollo 5K in any
hardwired fashion. An Apollo 5K Wiring Box (Optional Purchase) may be used in
the installation. For all configurations, please consider the rated amperages of
power sources, total loads, wires, and the Apollo 5K. Do not exceed limits.
The Apollo 5K factory default setting is “floating neutral” (i.e. the neutral and
ground are unbonded.
The unit should be configured with floating neutral when connecting the load
side of the Apollo to a separate ground (e.g. directly supplying power to a home
breaker panel).
The unit may be configured with a neutral-ground bond, a.k.a. “bonded
neutral”, which may be preferred for some o-grid applications. To bond the
neutral to the ground, please follow instructions according to the label on the
side panel of the Apollo as depicted in Fig. 5.1 and Fig. 5.2 below.
The Apollo ground port may be connected to a grounding rod, building rod, etc.
by a qualified electrician. Ensure the Apollo neutral-ground is appropriately
bonded or unbonded.
