3.5 Connection of the AC cabling
This is a Safety Class I product (supplied with a protective grounding terminal).
Uninterruptible protective grounding must be provided at the AC input
and/or output terminals and/or chassis grounding point located externally
on the product. See the following instructions:
a) The Phoenix Inverter Compact has a free floating AC output. The grounding
point located externally on the product must be used to ground the chassis.
The neutral output wire must be connected to ground to ensure proper
functioning of a GFCI (Ground Fault Circuit Interrupter).
b) Phoenix Multi / MultiPlus Compact : the output neutral wire will
automatically be bonded to the chassis (with the output ground relay, see
appendix 2) when no external AC source is available (backfeed / safety relay
open and product running in inverter mode, see appendix 2). When an external
AC source is provided, the ground relay opens before closure of the backfeed /
safety relay. Once closed, the backfeed / safety relay ensures that the neutral to
ground bond is provided by the external AC source. This is to ensure proper
functioning of a GFCI to be installed in the AC output of the Multi/MultiPlus.
- In a fixed (for example terrestrial) installation an uninterrupted chassis ground
may be provided by the AC input ground wire.
- In case of a mobile installation (connection to input AC with a shore power
cord), the ground connection is lost when the shore power cord is unplugged. In
this case the chassis of the product or the on - board section of the input ground
wire must be connected to the frame (of the vehicle) or the ground plate or hull
(of a boat).
- Marine applications: due to the potential for galvanic corrosion it is in general
not acceptable to connect the shore side ground to the ground plate or hull of
the boat. The proper and safe solution is to install an isolation transformer.
