1 SAFETY
Warning
ATS Panel should only be installed, maintained or serviced by a qualified electrician.
The generator set may start without warning whilst in AUTO mode.
Before undertaking any service or maintenance work, ensure the mains and generator supply are
isolated and generator is switched to off.
The generator is supplied with the battery disconnected/isolated for safety reasons and should not
be re-connected until all connections have been made.
Because of the nature of the equipment and the permanent mains connection, the terminals within
the generator may be LIVE even if the generator itself is not running.
2 INSTALLATION
Make sure that the Generator is at least one metre away from any building during operation.
Operate in a well ventilated unconfined area, so that fumes can be properly dispersed.
Silencer outlet should be facing an open area to prevent fumes being recirculated.
Consideration will also need to be made for refuelling and maintenance.
If installing in a confined area please consult manufacturer.
2.1 ELECTRICAL INSTALLATION
2.2 AC Wiring
Please ensure the correct cross sectional area of cable between the Alternator/Panel and
Distribution board used is adequate to carry the full rated continuous output of the generator,
allowing for de-rating in high ambient temperatures. Please consult IEE regulations as per the
correct sizing of cable and other issues regarding wiring. Flexible cable is recommended for
alternator connections allowing for a generous loop before the cable enters the alternator terminal
box because of the vibration caused by the set starting. If this is not possible a terminal box can be
fitted nearby and flex fitted between this and the generator terminal box. These precautions will not
be needed when fixing to a control box which is not attached to the Alternator. Please refer to
Wiring diagram.
2.3 DC WIRING
For the DC wiring we recommend 1.5mm if the generator is more than 10Meters away please
consult manufacturer for cable sizing. Please refer to Wiring diagram.

This button places the module into its ‘Automatic’ mode. This mode allows the module to
control the function of the load switching completely automatically. The module will
monitor the remote start input and mains supply status and once a start request is
made, the set will be placed on load.
Upon removal of the starting signal (or the mains supply returns), the module will
automatically transfer the load from the generator to the mains and remove the genset
starting instruction.
For further details, please see the more detailed description of ‘Auto operation’
elsewhere in this manual.
Operation is as AUTO MODE above but the load is not transferred back to the mains
supply when it is reinstated. This function is sometimes called “MANUAL RESTORE”
Once in Test on load mode the module will send a start request to the generator and
place the set on load. The set will remain on load when in this mode.
This mode allows manual control of the ATS functions. Once in Manual mode the
module will send a start request to the generator.
Breakers can be opened and closed using the transfer buttons detailed below.

Activation of an auxiliary input that has been configured to remote start
Activation of the inbuilt exercise scheduler.
6.1.2 STARTING SEQUENCE
To allow for ‘false’ start requests, the start delay timer begins.
Should all start requests be removed during the start delay timer, the unit will return to a stand-by
state.
If a start request is still present at the end of the start delay timer, start signal is given to the generator
set by the start/run output.
If the generator fails to become available before the generator failure timer expires. This is indicated
on the LCD display, but the starting signal remains active.
6.1.3 GENERATOR ON LOAD
