check, leave the closing springs “discharged” and circuit
breaker contacts “open”.
Outdoor storage is NOT recommended. If unavoidable,
the outdoor location must be well drained and a tempo-
rary shelter from sun, rain, snow, corrosive fumes, dirt,
falling objects and excessive moisture must be provid-
ed. Containers should be arranged to permit free circu-
lation of air on all sides and temporary heaters should
be used to minimize condensation. Moisture can cause
rusting of metal parts and deterioration of high voltage
insulation. A heat level of approximately 400 watts for
each 100 cubic feet of volume is recommended with the
heaters distributed uniformly throughout the structure
near the floor.
Indoor storage should be in a building with sufficient
heat and air circulation to prevent condensation. If the
building is not heated, the same general rule for heat as
for outdoor storage should be applied.
