Note: For single phase operation (SP-40, 60
and 100 only), connect input power to R
and S, leaving the T terminal open.
Note: Do not use phase adders (roto-phase)
on inverter driven equipment!
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 voltage. Verify connections as shown
on the schematic with each machine.
