1. If the ambient will be below -20
o
C, Graham
should be notified so a space heater can be pro-
vided inside the enclosure.
2. If the ambient will exceed 40
o
C, a source of
cooling will be required.
3. If the drive will be operated intermittently in
cold and/or humid conditions, precautions
must be taken to prevent condensation from
forming when the drive is off. A thermostati-
cally controlled temperature control should be
installed to maintain acceptable temperature
and moisture control. Consult Graham for fur-
ther recommendations.
1703 Series drives are cooled by fan(s) drawing air
through slots in the standard enclosure and across the
heatsink. The slots must never be restricted in any
way. The slots were covered for shipping. The cover-
ing material must be removed before operating the
drive.

The drive must be installed in a clean, dry environ-
ment unless special enclosure provisions are provided.
Periodically, the drive should be cleaned using a vac-
uum cleaner and a soft, long-bristled brush. Lightly
brush the dust from the drive components with the
brush and use the vacuum cleaner to remove the dust
as it falls. If available, clean dry compressed air at a
maximum pressure of 50 psi (3.4 atmospheres) may be
used to blow dust from the drive.
