5.2.2. Remote on/off
The Phoenix Smart IP43 Charger is equipped with remote on/off terminals, these terminals enable charging to be turned on or off
remotely dependent on their state.
There are 3 options to turn the Phoenix Smart IP43 Charger on using the remote terminal(s):
1. Interconnect / short the L and H terminals (factory default is a shorting link between L and H). The L and H terminal can be
interconnected /shorted via a switch, relay or other external device, like a battery management system (BMS).
2. Pull the H terminal to a high voltage level; when the voltage on the H terminal is above 2.9V (connected to battery positive for
example) the charger will turn on. The H terminal can be connected to a high voltage level via a switch, relay or other external
device, like a battery management system (BMS).
3. Pull the L terminal to a low voltage level; when the voltage on the L terminal is below 3.5V (connected to battery negative for
example) the charger will turn off. The L terminal can be connected to a low voltage level via a switch, relay or other external
device, like a battery management system (BMS).
To turn the Phoenix Smart IP43 Charger off using the remote terminal(s), both terminals need to have an open circuit relative to
each other and be left floating (no connection to a high or low voltage level).
5.2.3. Programmable relay
The Phoenix Smart IP43 Charger is equipped with a programmable relay, the relay can be used for external control based on the
selected relay mode (Alarm, Remote control, or Charging) and operational conditions.
There are 3 programmable relay terminals:
1. NO (Normally open)
2. C (Common)
3. NC (Normally closed)
When the relay is switched off there is a closed circuit between C and NC, and an open circuit between C an NO.
When the relay is switched on there is an open circuit between C and NO, and a closed circuit between C an NO.
Wire the relay terminals to an external device as necessary in order to achieve the desired signal/control.
Note:
The programmable relay function only works when AC input power is available and charging is enabled.
If charging is disabled by any means (the remote on/off terminals, via VictronConnect or a GX device) the
programmable relay functionally will also be disabled.
