This machine must be grounded. Grounding provides a path of least resistance to help divert current away from the operator in case of electrical malfunction.
Make sure the voltage of your power supply matches the specifications on the motor plate of the machine.
The PM2700 Shaper should be connected to a dedicated circuit, and protected by a circuit breaker or time delay fuse, with minimum amp ratings as shown in Table 1. Local codes take precedence over recommendations.
Model | Recommended circuit* |
|
|
1280100C (3HP 1PH 230V) | 15 Amp |
|
|
1280101C (5HP 1PH 230V) | 60 Amp |
|
|
1280102C (5HP 3PH 230V) | 30 Amp |
|
|
1280102C (5HP 3PH 460V) | 15 Amp |
*subject to local codes
Table 1
Voltage Conversion (3 Phase Shaper only)
On the 3 phase model, to convert from 230V to 460V, replace the 230V switch with the 460V switch (not included, order part no.
Extension Cords
The use of extension cords is discouraged. Try to position equipment within reach of the power source. If an extension cord becomes necessary, make sure the cord rating is suitable for the amperage listed on the machine's motor plate. An undersize cord will cause a drop in line voltage resulting in loss of power and overheating.
The chart in Table 2 shows the correct size cord to use based on cord length and motor plate amp rating. If in doubt, use the next heavier gauge. The smaller the gauge number, the heavier the cord.
