Electrical Safety

Connect the PTP to a power supply line that includes a switch or other adequate means of
disconnection from the electricity supply.
Only plug the PTP into an electricity supply socket that is provided with a protective ground
(earth) connection.
To ensure satisfactory and safe operation of the PTP it is essential that the green/yellow lead
of the line power cable is connected to a true electrical ground.
If any part of the PTP is not installed by a PerkinElmer Service Engineer, ensure that the line
power plug is correctly wired.
