Panel ATS (Automatic Transfer Switch)
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.
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
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
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 derating in high ambient temperatures.Please consult IEE regulations as per the
correct sizing of cable and other issues regardingwiring. 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 toa control box which is not attached to the
Alternator. Please refer to Wiring diagram.
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.
3 ATS Panel Equipment
3.1 ATS control – ENKO ATS 1.1
ATS1.1 automatic transfer unit is a microprocessor based digital unit monitoring the 3 phases
of the mains and controls the changeover of mains and generator contactors if a mains failure
on any phase is detected. The module is able to display all the parameters which are essential
for the basic gen-set transfer control.The module has 3 operation modes.Test on load, test off
