Figure 6. Installing Wire Connector
4. Install wire connector between the two flat washers. See Figure 6.
WARNING
!
Vibrator must be grounded using the power supply ground
wire (or other if specified in the NEC). Failure to properly
ground vibrator can cause severe injury or death.
5. Connect power supply ground wire (or other if specified in the NEC) to
ground vibrator terminal. Use closed loop wire connector only.
6. Reassemble wiring cover, o-ring, and rubber compression block(s),
taking care not to pinch the o-ring. Tighten cord grip around supply
line(s).
Thermistors and
thermostats
WARNING
!
Thermistors and thermostats are intended for motor winding
protection or to limit external motor surface temperatures.
They do not replace overload protection. Always install
overload protection. Failure to do so could result in severe
injury or death.
CAUTION
!
If installing low-voltage line to vibrator’s thermistor circuit
(frame size 70 and larger), make sure you install cord grip,
P/N 511546, on opening in wiring compartment. Without a
cord grip, moisture or material could enter terminal block
and damage vibrator. If cord is damaged, it could short power
supply or short to ground causing damage to vibrator.
1. If applicable wiring codes specify that low and high voltage circuits are
to be separated from each other, remove plug on back of wiring
compartment and install cord grip, P/N 511546.
2. Run low-voltage line to thermistor circuit and tighten cord grip. Ensure
wire is of proper voltage rating and size (see Table IV).
