Installation; Connecting The Equipment To The Main Supply; Selecting A Location; Changing Polarity - Air Liquide M 130 Owner's Manual

3.1 CONNECTING THE EQUIPMENT TO
THE MAIN SUPPLY
The equipment works within an input range of
±10%.
Check to ensure that the power outlet is equipped
with a fuse that is capable of carrying the amps
indicated on the data plate of this unit.

3.2 SELECTING A LOCATION

Special installation may be required
where gasoline or volatile liquids are present
(See NEC Article 511 or CEC Section 20). Do
not move or operate this equipment where it
could tip over. When selecting a location for
this equipment, ensure that the following
guidelines are followed:
1. Use data plate to determine input power
requirements.
2. The operator must have unobstructed access to
all controls and equipment connections.
3. Do not position equipment in small, closed
places. Ventilation of the power source is
extremely important. Make sure that the louvers
on the side panels are not obstructed and that
there is no risk of obstruction during operation.
4. Avoid areas where dust or other objects could
be sucked into the system.
5. Equipment must not obstruct corridors or work
activities of other personnel.
6. Position the power source securely to avoid
falling or overturning.
7. Understand the risk of falling equipment situat-
ed in overhead positions.
