CAUTION
After unpacking, check
if the product shows any
mechanical damage. Never
use the product when the
enclosure shows any visual
damage caused by harsh
handling, or when it has been
dropped accidentally.
Contact your local supplier
for further information.
This product is equipped with a ground relay that automatically connects the output Neutral to
the chassis (PE) in inverter mode (AC transfer switch is open). When AC is present at the input, the
ground relay will open just before the AC transfer switch closes. This behaviour enables correct
operation of an earth leakage circuit breaker (GFCI/RCD) that is connected to the output.
Heavy load hazard. Take care when lifting the unit by yourself. The use of two people to lift and
mount the unit is preferred. Make sure that the wall can easily support a load of 20 kilos. Use
appropriately sized screws. Mount the inverter/charger before connecting any wires or cables.
Always connect the negative (-) cable directly on the negative terminal of the battery, or on the “load side” of
a current shunt. Always keep positive and negative cables close to each other to minimize electromagnetic
fields. Double check for correct polarity, before connecting the battery cables to the battery!
To reduce the risk of explosion, never use this product in locations where there is danger of gas- or
dust explosions or where ignition protected equipment is mandatory. Never install the charger
directly on top of the battery or vice-versa.
This Class I product must be earthed! Always connect the PE wire or chassis ground screw between
the fans to your central ground (vehicle chassis, grounding system of your boat etc.)
The schematic on the right shows a typical standalone installation. No guarantees are given on the
compliance of any local electrical regulations. Please make sure that the complete installation is
made in accordance to all locally applicable electrical regulations.
Notes:
Please consult the following table to determine the correct battery cable size for each model. The given cable sizes are valid for cables installed in free air. Using a smaller cable size or a longer cable may cause the inverter to shutdown under heavy
load. Fire and burning hazards are present if the battery cables are insuciently sized for the expected current. Battery cable lengths longer than 3 meters, are not recommended.

The AC input must be protected by a fuse or magnetic circuit breaker (MCB) rated at 30A or less and wiring must be sized accordingly (check local regulations). If the AC input supply is rated at a lower value, the fuse or MCB should be down
sized accordingly.
An earth leakage circuit breaker with over current protection (RCBO) rated to support the expected load, must be included in series with the AC output. The AC output wiring must be sized accordingly. Please take into account that with the
AC Power Boost feature enabled, the ePRO Combi can add roughly 12A to the output during periods of peak power demand. Assuming a maximum transfer switch utilization, the total output current can reach a level of 30A + 12A = 42A.
Therefore the maximum RCBO rating is 40A.
Programmable relay 1 is congured standard as an alarm relay. This means that it will be activated once the ePRO Combi shuts down and jumps to an error mode. Relay 2 will be activated only a few minutes after the AC supply has become
available. In case of battery operation, Relay 2 will deactivate immediately. This can be used to switch less critical AC loads (i.e. electric boiler, aircon) on and o that are allowed to be supplied by the mains or generator only. Always include a
16A fuse in series with the programmable relay contacts.
The required contact specications for the trigger switches are 5V/5mA. The required contact specications for the remote switch are 60V/10mA. The maximum wire length between the switch and the ePRO Combi is 30m. The remote switch
will only operate when the main on/o switch is either in position I or II.
The battery temperature sensor must be attached to the main battery. An optional remote control will only operate when the main on/o switch is either in position I or II. In this case the power switch on the remote control panel will be used
to turn the ePRO Combi on and o.
The secondary charger output is limited to approximately 4A and has a slightly lower output voltage compared to the main battery connection. This output is intended to maintain the capacity of a starter battery and is diode isolated from the
main connection. A battery fuse of 10A should be installed in this line. A wire size of at least 2.5mm
2
should be used for this output.
