If the equipment is temporarily stored or machine
stops for an extended length of time, the following
precautions should be taken .
LOCATION
Store the equipment under the following condi-
tions.
" Free from rainfall and drops of water
" Clean and dry
" Free from corrosive gas and liquid
" Ambient temperature :
-100 C to 400 C
" Less vibration
INSTALLATION
Select a location described in STORAGE and in-
stall the equipment by proper procedure in keep-
ing the equipment in good working condition .
WIRING
Make connections in reference to the interconnection
diagram furnished on your order and the follow-
ing .

CAUTIONS WHEN WIRING
Main Circuits
Use 600 V PVC insulated wires or cabtyre cables
with the current carrying capacities of the com-
bined DC motor for AC main circuit terminals
(U, V, W) and DC main circuit terminals (P, 1) .
Field Circuits
Use 600 V PVC insulated wires or cabtyre cables
with the current carrying capacities of the com-
bined DC motor for field power circuit terminals
(Uo . Wo . U1, W1)
and field circuit terminals (J,
K) .
Use stranded wires of cross-section 5 .5 mmz
or larger for field circuit terminals (J, K) .
Signal Circuits
Use shielded wires or twisted wires of twisting
pitches 20 mm or smaller for the speed setting
circuit terminals (11 to 16), speed feedback ter-
minals (3 to 5), tachometer circuit terminals (38
to 40) .
