SECTION II
INSTALLATION
Before starting the installation, read this section thoroughly. In addition, a through review of the Ratings And
Specifications (Section VII) is recommended. The following installation guidelines should be kept in mind when
installing the controller.
INSTALLATION GUIDELINES
1. CONTROLLER MOUNTING - Controllers rated 1/6 - 3 HP may be mounted either vertically or hori-
zontally. Controllers rated at 5 HP may only be mounted vertically. Never mount the controller upside
down, immediately beside or above heat generating equipment, or directly below water or steam pipes.
The controller must be mounted in a location free of vibration.
Multiple controllers may be mounted side by side, as close to each other as the mounting feet will allow.
However, if a Model 2601 or 2602 Controller enclosure has Cover Hinges (Option 1638), 4 inches (102
mm) clearance must be provided on the hinged side of the enclosure to accommodate the swing of the
cover.
The minimum clearance at the top and bottom of the controller may be as narrow as the conduit fittings
allow.
2. ATMOSPHERE - The atmosphere surrounding the controller must be free of combustible vapors, chem-
ical fumes, oil vapor, and electrically conductive or corrosive materials.
The air surrounding an enclosed controller must not exceed 40 degrees C (104 degrees F), and the air sur-
rounding an open-chassis controller must not exceed 55 degrees C (131 degrees F). Minimum air tempera-
ture is 0 degree C (32 degrees F) for enclosed and open-chassis controllers.
Model 2601 and 2602 Controllers (except 5 HP enclosed models) require a natural convection flow of air
over the pins on the back of the controller to dissipate the heat generated by the controller. Allow 4 inches
(102 mm) clearance on all sides from solid objects which block the flow of air to the pins.
3. CONTROLLER CONSTRUCTION - Series 2600/2610 controller bases are made of die-cast aluminum
with a powdered epoxy finish.
Series 2600/2610 Controller enclosures are totally enclosed, nonventilated, and comply with NEMA Type
4 and 12 standards. There is an oil resistant synthetic rubber gasket between the cover and base. Those
models with integral operator controls include flexible boots to seal the switches, and a seal for the
MOTOR SPEED potentiometer.
Series 2600 enclosure covers are molded of Noryl, which is not affected by most water-based solutions,
detergents, acids, and bases. However, the cover may be softened by heptane, acetone, and other haloge-
nated and aromatic hydrocarbons, so install Series 2600 Controllers in a location free of these substances.
Series 2610 enclosure covers are made of a die-cast aluminum alloy.

BOOK0795-F

4. BRANCH CIRCUIT PROTECTION - The National Electrical Code requires that a two-pole fused dis-
connect switch be installed in the AC line supply to the controller. Although an optional two-pole circuit
breaker (Option 1010) is available for Model 2601 Controllers, this circuit breaker should not be consid-
ered as branch circuit protection. However, the existing branch circuit may already provide the required
protection. Refer to the National Electrical Code and local codes.
5. LINE SUPPLY - The controller should not be connected to a line supply capable of supplying more than
100,000 amperes short-circuit current. Short-circuit current can be limited by using an input supply trans-
former of 50 KVA or less, or by using correctly sized current limiting fuses in the supply line ahead of the
controller. Do not use a transformer with less than the minimum transformer KVA listed in Table 9, page
33.
If rated line voltage is not available, a line transformer will be required. If the line supply comes directly
from a transformer, place a circuit breaker or disconnect between the transformer secondary and the con-
troller. If power is switched in the transformer primary, transients may be generated which can damage the
controller. See Table 9 (page 33) for minimum transformer KVA.
Do not use power factor correction capacitors on the supply line to the controller.
A 12-joule metal oxide varistor (MOV) is connected across the controller terminals. If higher energy tran-
sients are present on the line supply, additional transient suppression will be required to limit transients to
150% of peak line voltage.
When a 115 VAC line supply is used, connect the white (common) wire to Terminal L2 and connect the
remaining (hot) wire to Terminal L1.
6. ISOLATION TRANSFORMER - While not required, an isolation transformer can provide the following
advantages:
a. Reduce the risk of personal injury if high voltage drive circuits are accidently touched.
b. Provide a barrier to externally generated AC supply transients. This can prevent controller damage from
abnormal line occurrences.
c. Reduce the potential for damaging current if the motor armature, motor field, or motor wiring become
grounded.
7. GROUNDING - Connect the green or bare (ground) wire of the line supply to the ground screw located
near the top conduit entry hole in the controller base. Then ground the controller base by connecting the
ground screw to earth ground.
The motor frame and operator control stations must also be grounded.
Personal injury may occur if the controller, motor, and operator stations are not properly grounded.
8. WIRING PRACTICES - The power wiring must be sized to comply with theNational Electrical Code,
CSA, or local codes. Refer to the controller data label for line and motor current ratings.
Do not use solid wire

BOOK0795-F
5
Signal wiring refers to wiring for potentiometers, tachometer generators, and transducers. Control wiring
refers to wiring for operator controls. Signal and control wiring may be run in a common conduit, but not
in the same conduit with the power wiring. In an enclosure, nonshielded signal and control wiring must be
kept separated from power wiring and only cross at 90 degree angles.
If shielded wire (such as Alpha 2422 - two conductor, 2423 - three conductor, 2424 - four conductor) is
used for the signal and control wiring, connect the shields to chassis ground (ground screw on the control-
ler base) and tape the opposite ends of the shields.
Two 3/4-14 NPT threaded holes are provided for conduit entry, one each in the top and bottom of the con-
troller base.
9. OPTIONS - This equipment manual is for use with the basic controller. If options are installed in the con-
troller, they will be identified on the controller data label. The instruction sheets supplied with the options
should be reviewed before the controller is installed.
INSTALLING THE CONTROLLER
1. Remove the controller front cover (if used) by removing the four cover screws.
2. Check components in the controller for shipping damage. Report shipping damage to the carrier.
3. Check the controller and motor data labels to be sure the units are electrically compatible.
4. Be sure the controller has been calibrated correctly for the motor being used. Calibration is performed by
changing the position of a Jumper (J4) on the controller control board to comply with Table 3. To change
the position of Jumper J4, pull the jumper from the control board and then push it onto the appropriate two
pins on the board. For the location of J4, see Figure 22 (page 43) or Figure 23 (page 44) as applicable.
5. Check the positions of Jumpers J1, J2, and J3 on the control board. For the locations of J1, J2, and J3, see
Figure 22 (page 43) or Figure 23 (page 44) as applicable. For a 230 VAC line supply and a 180V armature
motor, Jumper J1 must be in the 230V position, and Jumpers J2 and J3 must both be in the 180V position.
For a 115 VAC line supply, J1 must be in the 115V position, and J2 and J3 must be in the 90V position.
NOTE: If Option 1001 (Armature Contactor, Unidirectional), 1004 (Armature Contactor, Reversing), or
1775 (Signal Interface) is to be installed in the controller, do not offset the five-position plug
(supplied with the option) at Connector J1 on the control board. Do not confuse Connector J1
with Jumper J1. Refer to the Instruction Sheet (ISP0703, ISP0666, ISP0653, respectively) sup-
plied with the option for connection instructions.

INITIAL STARTUP
1. Open the controller cover (if used) by removing the four cover screws.
2. Be familiar with all options installed in the controller by reviewing the instruction sheets supplied with the
options.
3. Be sure all wiring is correct and all wiring terminations are tightened securely.
4. Be sure the controller is calibrated correctly. See steps 4 and 5 under “Installing The Controller” on page 5.
5. Be sure the AC supply voltage to the controller agrees with the controller data label.
6. The potentiometers in the controller are factory adjusted as shown in Table 4. These settings will provide
satisfactory operation for most applications. If different settings are required, refer to “Adjustment Instruc-
tions” starting on page 21.
7. If the controller has a cover, place it on the controller and secure it with the four cover screws.
8. Turn-on the AC supply to the controller.
9. Check motor rotation, as follows:
a. If a MOTOR SPEED potentiometer is used, turn it fully counterclockwise. If an external signal is used
for the speed reference, set it at minimum.
b. If a RUN-STOP-JOG switch is used, place it in RUN position. Otherwise, initiate a Run command.
c. Turn the MOTOR SPEED potentiometer clockwise or increase the speed reference signal, as applica-
ble. To stop the motor, place the switch in STOP position or initiate a Stop command, as applicable.
If the motor rotates in the wrong direction, turn-off the AC supply to the controller, and then interchange
the motor armature leads at the motor connection box or at the controller terminal board.
