Now connect the other side of tube to the fume extractor of the laboratory.
2.5 Power supply
Power supply line must have a ground connection (yellow/green, green or bare wire).
Do not use the blue/white wire (neutral of power line). Power supply neutral has to be referred to ground.
Carefully check that:
A strong ground connection
is made available in the lab to assure the unit works correctly. Do not
connect a Milestone unit without ground connection.
A dedicated ground connection
direct from the main electric box (cabinet) of the laboratory to our
unit is ideal to eliminate any possible interference/electronic noise originated by other instruments
supplied with the same line.
Power supply line wires
(their size and distance from the switch board) used in the laboratory are
compliant with the label positioned on the back side of our units.
Plug/socket
is visible during the normal use and easily accessible.
Power line protection:
115V: Miniature circuit breaker curve C, 20A, interruption more than 6000A.
230V: Miniature circuit breaker curve C, 16A, interruption more than 6000A.
Residual current device: 30mA (Class I device).
Only 230V version: a schuko terminated power cord is provided.
The 115V version is not terminated.
2.6 Electrical installation
Before connecting the plug to the laboratory’s socket CHECK that the power supply
voltage of the unit matches the power supply line of the laboratory.
Damages occur when wrong power supplies the instrument.
