9.0 SUGGESTED SPARE PARTS
It is suggested that where 10 or more units are in service, one or more complete circuit boards be stocked as spares for ease of
maintenance and minimum downtime. All circuit boards are wired directly to screw type terminal strips (no solder connections) and can
be easily changed on location.
Fuse F2 is a spare fuse attached to AC circuit boards but not wired in the circuit. See Figure 1. If fuse F2 is used to replace fuse F1, it is
recommended that another be purchased and attached to circuit board as a spare.
