If the air entrance ports of the power source are provided with air filter mats,
it should be considered that the duty cycle of the power sources reduces
in dependence of the increasing degree of soiling of the air filter mat. The
cleaning interval for the air filter mat must be determined as experience
shows because the pollution of the filter mat depends on the ambient
conditions. The power sources must be operated with air filter mats, if
environmental conditions with increased fuses, aerosols, metal dust etc. are
concerned. The user must regularly check the degree of soiling of the filter
mat. Dirty filters must be replaced!
Oil-contaminated filter mats can cause a fire due to flying sparks (grinding)!
• A safety check of the power source is required at least every 12 months. A
repeat check must be carried out by a skilled electrician. A check list with
the individual points to be checked can be provided by the manufacturer.
• Please observe the national and international standards and regulations
regarding the safety check.
• The mounting area should be free of dust and aggressive agents.
• The ground should be horizontal and flat (admissible inclination angle
max. 10º).
• The distance between power source and environment should at least be
0.50 m to allow the cooling air to circulate unhindered.
• The cooling air inlets and outlets must not be blocked by things such as
welder’s apron, tissues, drawings, walls etc.
The admissible ambient temperature may vary from -10°C to +40°C.
Relative air humidity:
up to 50% at 40°C (thawing excluded)
up to 90% at 20°C (thawing excluded)
The protection class IP 23 does not allow to install the machine in the rain.
If required, the machine must be covered on a large surface. In the process,
ensure that the through-flow of cooling air is not impaired.
The machine should be stored in a dry and clean room. The ambient
temperatures must not exceed -20
0
C and +45
0
C.
In case of a longer storage, the machine should be covered with a suitable
foil.
ATTENTION!
DANGER!
