ELECTRICAL CABLES AND AIR LINE


120 VAC INPUT
The alternate input voltage to the control is 120 Vac, 1 Ph, 60 Hz. The max amperage
needed is 7.5 amps and the control has a circuit breaker with a trip amperage of 10
amps..

230 VAC INPUT
The required input voltage to the control is 230 Vac, 3 Ph, 60 Hz. The amperage
needed is 10-20 amps depending on the motor size. If unsure of the amperage
needed, the name plate on the side of the Pacific Scientific drive will give the number
of the control or check the disconnect fuses for the correct fuse size.

460 VAC INPUT
If your plant has only 460 Vac power then a step down transformer is needed in order
to run the servo feed. If you purchased the transformer from Rapid Air, then all that is
needed is to connect and wire the 460 volt line to the transformer. If you did not
purchase a transformer from Rapid Air then a transformer, 3 KVA for the 100S and
200S servos and 6KVA for the 300S servos, 460/230 VAC 3PH, 60HZ step down
transformer is needed before proceeding with the electrical portion of the installation.

The electrical control enclosure is shipped completely ready to be connected to the
mechanical feed. Connected to the bottom of the enclosure are (2) cables with keyed
screw type connectors for connection to the motor. If the series 200 or 300 was
purchased, (1 or 2) push-on connectors for connection to the air valves for solenoid
actuation of the pilot release and or anti-backup valve are included. The third
connector is used to interface the cutter to the controls.

Position the electrical enclosure at a convenient location near the mechanical feed and
attach the cables. The motor cables are easily identifiable by the amount of pins in the
plugs. The solenoid cables if any can now be attached and checked for proper
location when the feed is up and running.

An air line must be connected from the shop air to the air inlet of the servo feed. The
air should be at least 80 PSI continuous and should be dry filtered andlightly lubricated
for the best operation of the servo feed. The air inlet on the servo feed is a 3/8-18 NPT
pipe tap. The minimum air line size requirement is 1/2”ID hose. - (2 CFM)
