Electrical Connection

The power entry module can be found on the back of the unit and consists of a three-pole socket for the
cord set, an extractible fuse box with two fuses (see Technical specifications) and the main switch.
Insert correctly the three-pole plug of the cord set into the power entry module.
WARNINGS:
•
Before plugging the cord set into the mains, check to make sure the equipment has not
undergone any damage during transport and make sure the voltage corresponds to that of the
unit (see the rating plate on the side of the unit).
•
For safety purposes the cord set is provided with an earthed plug.
•
Make sure that power supply socket has been earthed.
•
The equipment must only be connected to the mains which are in conformity with EEC standard
directives, to avoid the risk of electric shock, in fact, this appliance must always be connected to
power supply networks with protective earth.
•
When using an extension lead, make sure that this has been earthed
•
Failure to comply with the above instructions may lead to dangerous electrical discharge causing
hazard to persons and the machine function.
CAUTION:
•
If an extension lead is used with Endolaser together with other equipment, make sure that the
total ampere rating of all the devices in question does not exceed that which is consented by the
cable and does not in any case exceed 15A.
•
Once you have checked that installation and assembly have been carried out according to
instructions provided up to this point in the manual, switch on the machine making sure that the
display screen is turned on correctly.

Remote Interlock connector

The unit is provided with a safety key (interlock) which consists of a DIN plug on to be inserted at the
back of the unit. The machine WILL NOT WORK without this this without the interlock security key. The
plug allows the operator to connect this with the local interlock switch. (Use for the interlock switch a 2-
way micro switch this is normally turned off.)
The safety key or interlock switch interrupts the invisible laser emission only and not the Led power
supply.
WARNINGS:
•
Before starting the equipment, make sure that the INTERLOCK key that allows it to start is
inserted.
CAUTION:
•
If you want to install the external interlock circuit, contact only qualified technicians and provide
these professionals with the scheme that complies with the configuration of the treatment room.
Failure to properly install the device could result in serious eye damage.
If an external safety interlock circuit is required, a minimum diameter of 0.6mm, 20m max, with a shield
connected to the ground must be provided.
On the safety circuit side, a microswitch with one normally closed path must be provided.
This circuit is an external safety device: it allows to interrupt laser therapy treatments if there is a door
opening inside the room where the treatment is delivered.
