ELECTRICAL CONNECTIONS
1.0 Wiring the Unit (3 phase)
All repair or disassembly work must be performed
by qualified personnel. Before inspecting the
electrical system, always turn the main power
switch OFF before opening the door of the circuit
cabinet.
Check that your power supply meets the requirements
given in the machine specifications. Use an allen wrench to
unlock the circuit cabinet door and open it.
Feed the power supply cable from your distribution
panel through the side of the circuit cabinet. Connect the
customer's supply conductors to the main disconnect at L1,
L2 & L3. Connect the earth ground conductor to the adjacent
ground terminal block.
Before operating the folder for the first time, measure
the line to line voltage to determine where to set the trans-
former tap. Turn off the main disconnect and move the 7L3
tap of the transformer to the appropriate voltage tap of the
transformer.
Turn the main power switch to the "ON" position.
Switch the pumps on momentarily and check for proper
pump rotation as indicated by the rotation arrow on the
respective pumps. Immediately turn off the pumps if the
rotation is wrong. If both motors are turning in the wrong
direction, switch any two wires at the main disconnect
switch. If only one rotation is incorrect, interchange any two
of the three wires #1, #2, or #3 at their appropriate terminal
block connection point.
1.1 Pump & Blower Connections
Once the pump and blower rotational directions have
been checked and verified, connect the vacuum hose and the
blower hose to their appropriate tubes and secure them with
hose clamps.
