WARNING
– A service tent [reference: Pelsue Cabinet Mounted
Service Tent; Pelsue (800–525–8460) P/N
CM564866M] must be in place prior to opening the
main doors of the SC4812ET RF or Power Cabinet
during times of inclement weather (rain, snow, sleet,
or hail). This will prevent moisture from being drawn
into the electronics by internal fans and damaging the
equipment.
– A service tent [reference: Pelsue Cabinet Mounted
Service Tent; Pelsue (800–525–8460) P/N
CM564866M] with a heater is required to service the
SC4812ET RF Cabinet when temperatures are below
–10 Deg C (14 Deg F). Temperatures inside the tent
should be above 0 Deg (32 Deg F) prior to opening
the main cabinet door. This will prevent a rapid
temperature change to the electronics that could result
in a site outage.
