Each lift should have a
dedicated circuit with a 30 Amp
double pole breaker or time
delay fuse.
Wiring must comply with all
local electrical codes.
Electrical code requires a
service disconnect for this
device. We suggest this service
disconnect be located near the
point of operation.
Wiring is not complete until unit
has been tested, see
STEP 15
for details.
