4.6.2 Voltage Sense
Two sense wires may be connected to compensate possible battery cable losses
during charging. Use wires of at least 0.75mm
2
. For connection see Appendix 0.
4.6.3 Temperature Sensor
The temperature sensor supplied with the product may be used for temperature-
compensated charging (see Appendix
0
). The sensor is isolated and must be mounted
on the batteries minus pole.
4.6.4 Remote Control
The product can be operated remotely in two ways.
•
With an external switch.
•
With a Phoenix Multi Control panel.
For connection of the switch see Appendix 0.
Observe the following when using an external switch:
•
Only functions if the switch on the product is switched to the "on" position.
•
Not to be connected if a remote control panel is connected.
For connection of the remote control panel, see Appendix 0.
Observe the following when using a remote control panel:
•
Only functions if the switch on the product is switched to the "on" position.
4.6.5 External Relay
The maximum current that can be switched through from the AC input to the AC
output is 16 A (optional: 30 A). At more than 30 A an external contactor is needed:
please consult your supplier.
4.6.6 Parallel Connection
The MultiPlus can be connected in parallel with several identical devices. To this end,
a connection is established between the devices by means of standard RJ45 UTP
cables. The
system
(one or more Multi’s plus optional control panel) will require
subsequent configuration (see Section 5).
In the event of connecting MultiPlus units in parallel, the following requirements must
be met:
•
A maximum of six units connected in parallel.
•
Only identical devices with the same power ratings may be connected in parallel.
•
Battery capacity should be sufficient.
•
The DC connection cables to the devices must be of equal length and cross-section.
•
If a positive and a negative DC distribution point is used, the cross-section of the connection
between the batteries and the DC distribution point must at least equal the sum of the
required cross-sections of the connections between the distribution point and the MultiPlus
units.
•
Place the MultiPlus units close to each other, but allow at least 10 cm for ventilation
purposes under, above and beside the units.
•
UTP cables must be connected directly from one unit to the other (and to the remote panel).
Connection/splitter boxes are not permitted.
•
A battery-temperature sensor need only be connected to one unit in the system. If the
temperature of several batteries is to be measured, you can also connect the sensors of
other MultiPlus units in the system (with a maximum of one sensor per MultiPlus).
