NOTES FOR THE ELECTRICIAN
Use a three-conductor hard-service or
junior hard-service minimum #8 AWG
flexible cord with ground to connect the
machine to a protected branch circuit
suitable for a 10 HP, 230 V / 460 V 2-pole,
three-phase induction motor.
The motor
is pre-wired for operation with 230 V, 60
Hz power.
Open the terminal box (Fig. A1) and
connect L1, L2 and L3 to the proper
terminal blocks (Fig. A2) and the earthing
conductor to the terminal. Torque the
terminal block screws to 4.5 to 7 lb-in. Jog
the power switch and check for proper
cutterhead rotation. Interchange any two
line leads to reverse.
gROUNDINg INSTRUCTIONS
This machine must be grounded while
in use to protect the operator from electric shock.
This tool should be connected to a grounded metal
permanent wiring system; or to a system having an
equipment-grounding conductor. Terminate the
connecting cord earthing conductor in the
(earth
or ground) terminal of the terminal block. Make certain
the other end is securely bonded to the branch circuit
ground.
460 VOLT OPERATION
The unit can be reconfigured for 460 V, 60 Hz operation.
To do this :
1. Reconnect the motor for 460 V according to motor
nameplate wiring diagram.
2. Change the transformer primary voltage tap from
Terminal 3
(230 V) to
Terminal 4
(460 V) (Fig. A2).
3. Replace the 22 A to 32 A overload (shown in Fig.
A3) with an overload block rated from 11A to 17A.
The current setting should be set to match the
motor nameplate’s full-load amp rating.
(Call Delta
Machinery at (800) 223-7278 to order this part and
for help on installation.)
4. Torque the overload and contactor terminal screws to
14.2 to 26.6 lb-in.
5. Be sure the overload is on
"AUTO"
reset.
MOTOR SPECIFICATIONS
Model 22-610 is equipped with a 10 HP three phase motor prewired for 230 V, 60 Hz power. The unit can be recon-
figured for 460 V, 60 Hz operation.
