1.5 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 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: the output neutral wire will automatically be
bonded to the chassis (with the output ground relay, see appendix) when no
external AC source is available (backfeed / safety relay open and product
runnig in inverter mode, see appendix). 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.
The terminal block can be found on the printed circuit board, see Appendix A. The shore or
mains cable must be connected to the Multi with the aid of a three-wire cable. Use a three-
wire cable with a flexible core and a cross section of 2.5 or 4 mm²
Procedure
Proceed as follows to connect the AC cables:
•
The AC output cable can be connected directly to the terminal block containing the
words "AC-out". The terminal points are indicated clearly. From left to right: "PE"
(earth), "N" (neutral) and "L" (phase).
•
The AC input cable can be connected to the terminal block containing the words "AC–
in". The terminal points are indicated clearly. "PE" (earth) "N" (neutral) and "L" (phase).
1.6 Optional Connections
A number of optional connections are possible:
1.6.1 Second Battery
The Phoenix Multi/ MultiPlus has a connection for charging a starter battery. For connection
see Appendix A.
