CAUTION
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 SC 4812ET
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 SC 4812ET RF Cabinet
when temperatures are below –10 degrees C (14 degrees
F). Temperatures inside the tent should be above 0 degrees
C (32 degrees F) prior to opening the main cabinet door.
This will prevent a rapid temperature change to the
electronics which could result in site outage.
