The 70945 operates on 115 VAC, 50/60 Hz
only. Step-down transformers may be used to
convert 230/460 VAC to 115 VAC if necessary.
The hot side of the 115 VAC should be con-
nected to the motor thermostat, the return line
from the motor thermostat should be connected
to the terminal strip marked TB1-L1, and the
neutral side to terminal strip RE1-8. (See Figure
3 on page 9.)
The thermostat is a temperature sensing protec-
tor, mounted on the motor. The two leads from
the device must be connected to the control cir-
cuit which initiates corrective action.
The motor armature, field and thermostat wiring
can be located in the same cable or conduit as
allowed by the National Electrical Code, Article
300-2.
It is recommended that a fused disconnect be
installed ahead of the controller. Consult your
local codes.
Use stranded wire, minimum gauge 14 AWG for
all connections. Long cable runs may require
the use of a larger gauge than normal to avoid
excessive voltage drop.
Connect the green or bare wire of the line sup-
ply to the ground screw located near the top
conduit entry hole in the controller case. Then
ground the controller case by connecting the
ground screw to earth ground.
The motor frame and remote control station(s)
must also be grounded.
While an isolation transformer may not be re-
quired, it can provide the following advantages:
1. Reduce risk of personal injury if high
voltage drive circuits are accidently
touched.
2. Provide a barrier to externally generated
AC supply transients. This can prevent
controller damage from abnormal line
occurrances.
3. Reduce the potential for damaging cur-
rent if the motor armature, motor field, or
motor wiring become grounded.
Do not use power factor correction capacitors
on the supply line to the controller.
> Personal injury may occur if the
controller, motor, and operator station(s)
are not properly grounded.
