B&C Technologies HE-35 Installation And Operation Manual page 30

This machine must be installed, adjusted, and serviced by a qualified electrical
maintenance personnel familiar with the construction and operation of this type
of machinery. They must also be familiar with the potential hazards involved. If
this warning is not observed, personal injury or equipment damage resulting in
voiding the warranty may result.
If controlling the AC drive with a parameter unit, the machines computer and
its safety features are bypassed. This could allow the basket to rotate at high
speeds with the door open. When using a parameter unit to control the AC
drive, a large sign should be placed on the front of the machine warning people
of the imminent danger.
Note: Wire sizes shown are for copper, THHN, 90 conductor per NEC article 310 (USA).
The machine should be connected to an individual branch circuit not shared with lighting or other
equipment.
Because this is a vibrating machine, the use of SO cable or similar, with a twist-lock plug, to connect
the machine to main power is recommended. A shielded liquid tight or approved flexible conduit
with proper conductor of correct size installed in accordance with National Electric Code (USA) or
other applicable codes is also acceptable. The connection must be made by a qualified electrician
using the wiring diagram provided with the machine. See the Electrical Connection data Chart for
correct wire sizes.
For personal safety and for proper operation, the machine must be grounded in accordance with
state and local codes and in the USA in accordance with the National Electric Code, article 250-96.
The ground connection must be to a proven earth ground, not to conduit or water pipes.
Do not connect the ground to the neutral (N) leg at the terminal strip (if so equipped).
If a DELTA supply system is used, the high leg should be connected to T, since control voltage is
derived from R and S.
Insure that the control transformer taps are connected in accordance with the incoming line volt-
age. Verify connections as shown on the schematic with each machine.
Never touch terminals or components of the AC drive unless power is discon-
nected and the "'CHARGE"' indicator LED is off. The AC drive retains potential
deadly voltage for some time after the power is disconnected. There are no user-
serviceable parts inside the AC drive. Tampering with the drive will void the
warranty.
