Introduction
The VE Transfer Switch is designed to take over automatic switching between
different power sources. For example, between a generator and the shore,
between an inverter and a generator, or between an inverter and the shore.
It has two inputs and one output and automatically transfers the available AC
power from one of the inputs to the output. It can be used with any Victron
Energy inverter, providing the inverter power rating does not exceed the
transfer switch power rating.
The transfer switch can also be used to allow a MultiPlus inverter/charger to
connect to two different AC sources, like shore power and a generator, instead
of only being able to connect to a single AC source.
Operation
The transfer switch is situated between a generator or shore power and the
inverter.
If the voltage level or the frequency of the generator or the shore power
varies on input 1, the transfer switch will switch to the inverter on input 2.
Once the generator or the shore supply has remained continuously stable, the
transfer will switch back to input 1 with a delay of approximately 10 seconds.
This way, the appliances that are connected to the output are protected
against damage from voltage drops.
During transfer between one of the power sources from input 1 to input 2 or
vice versa, the appliances are not supplied with power for a short time.
Because of this, computers, electronic devices etc., that are connected to
this group might lose data.
The transfer switch can be used with any type of inverter, but the best
results, however, are obtained with an inverter from Victron Energy.
Installation
WARNING: Make sure that all AC power sources are switched off or
disconnected before and during installation.
Mounting:
- Install the transfer switch in a dry and well-ventilated area.
- To gain access to the transfer switch, remove the four screws in the front panel.
- The transfer switch can be wall-mounted by using the four holes in the rear of the casing.
Electrical connections:
- The input cables (mains/generator) and the inverter (or inverter/charger) and the output cable (to the appliances) should be connected according to the connection diagram as shown below.
- The input and output cables must have the correct core thickness for a safe installation. Undersized cables can cause overheating of the cables. The maximum cable core thickness is 6mm².
- Use the provided cable glands to pass the input and output cables through the casing.
- Tighten all connections with a nominal torque moment of 1.2Nm. This is to limit transition resistance as far as possible. Loose connections can cause dangerous overheating of the terminals.
Digital Multi Control panel connection:
When the transfer switch is used together with a MultiPlus and a Digital Multi
Control panel (DMC):
- Connect the transfer switch Auxiliary contact 1 and 2 of relay K2 (NO) to the screw connector on the back of the DMC as indicated in the connection diagram below.
- When the transfer switch auxiliary contact is open, the MultiPlus current limit is controlled by the knob on the front of the DMC. The display on the DMC will show the current limit value.
- When the transfer switch auxiliary contact is closed, a pre-set (generator) current limit is sent to the MultiPlus. The display on the DMC will show the text: “GEN”.
- For more information on this feature and on how to set the preset (generator) current limit see the Digital Multi Control Panel manual.

Control panel.
Fusing, earth leakage protection and grounding:
- The AC input and output wiring must be protected by fuses or miniature circuit breakers (MCBs) that are suitable for the system’s wire cross-section.
- External earth leakage switches (RCDs or RCCBs) must be integrated with the transfer switch wiring.
- All ground connections of the power sources and power consumers must be connected to the central ground connection of the ship or the electric installation.
Configuration:
In most cases, there is no need to configure the transfer switch. The transfer
switch is ready for use straight after installation.
However, in some specific circumstances, an adjustment of the “switch on
delay” of input 1 is needed. Make the delay time adjustment using a small
flat-blade screwdriver.
