Storage procedure
Whenever possible, store the recloser
indoors. The storage environment must be
clean, dry and free of such items as:
construction dust, corrosive atmosphere,
mechanical abuse and rapid temperature
variations.
Space heating
Space heating for the controller must be
used for both indoor and outdoor storage to
prevent condensation and corrosion. The
controller space heater should be connected
to a 120 Vac auxiliary supply at terminal
block X1 as discussed in "Connecting the
auxiliary voltage supply" on page 21 of this
instruction manual. (Refer to the wiring
diagrams provided with the order specific
drawings for terminal numbers and
terminal block location.) After these
connections have been made, circuit
breaker CB2, as shown on Figure 10, must
be switched to the "on" position.
