Installation
Moun�ng
• Drive components are sensi�ve to electrosta�c discharge. Avoid direct contact with the circuit
• board. Hold the drive by the chassis only.
• Protect the drive from dirt, moisture, and accidental contact.
• Provide sufficient room for access to the terminal block and calibra�on trim pots
• Mount the drive away from heat sources. Operate the drive within the specified ambient opera�ng
• temperature range.
• Prevent loose connec�ons by avoiding excessive vibra�on of the drive.
• Mount the drive with its board in either a horizontal or ver�cal plane. Six 0.19" (5 mm) wide slots
• in the chassis accept #8 pan head screws. Fasten either the large base or the narrow flange of the
• chassis to the subplate.
• The chassis should be earth grounded. Use a star washer beneath the head of at least one of the
• moun�ng screws to penetrate the anodized chassis surface and to reach bare metal.
Heat Sinking
The RGA400-10 requires an addi�onal heat sink when the con�nuous armature current is above 7
amps. Use heat sink kit part number 223-0235. Use a thermally conduc�ve heat sink compound
(such as Dow Corning 340® Heat Sink Compound) between the chassis and the heat sink surface for
op�mal heat transfer.
Wiring
Use 18 - 24 AWG wire for logic wiring.
Use 14 - 16 AWG wire for AC line (L1, L2 115V, L2 230V) and motor (A1, A2, F1, F2) wiring.
Shielding Guidelines
As a general rule, it is recommended to shield all conductors. If it is not prac�cal to shield power
conductors, it is recommended to shield all logic-level leads. If shielding of logic-level leads is not
prac�cal, the user should twist all logic leads with themselves to minimize induced noise. Refer to
the user's manual for details on earth grounding shielded wires and filtering.
Fusing
The drives provide on board fusing for the AC line (L1, L2 (230)). Fuses are fast ac�ng fuses. RGA400-3
models contain fuses rated for 8A at 250 VAC. RGA400-10 models contain fuses rated for 20A at
250 VAC.

READ ALL SAFETY WARNINGS BEFORE INSTALLING THIS EQUIPMENT
Continuous
Armature
• DO NOT INSTALL, REMOVE, OR REWIRE THIS EQUIPMENT WITH POWER APPLIED. Have a
Armature Horsepower
• qualified electrical technician install, adjust and service this equipment. Follow the Na�onal
Current (Amps) Range
• Electrical Code and all other applicable electrical and safety codes, including the provisions of the
• Occupa�onal Safety and Health Act (OSHA), when installing equipment.

3.0
• Circuit poten�als are at 115 or 230 VAC above earth ground. Avoid direct contact with the printed
1/10 - 1/4
• circuit board or with circuit elements to prevent the risk of serious injury or fatality. Use a non-
1/4 - 1
10.0* • metallic screwdriver for adjus�ng the calibra�on trim pots. Use approved personal protec�on
1/2 - 2
• equipment and insulated tools if working on this drive with power applied.
• Reduce the chance of an electrical fire, shock, or explosion by using proper grounding techniques,
• over-current protec�on, thermal protec�on, and enclosure. Follow sound maintenance procedures.
• ACE strongly recommends the installa�on of a master power switch in the line voltage input. The
• switch contacts should be rated for 250 VAC and 200% of motor nameplate current.
• Removing AC line power is the only acceptable method for emergency stopping. Do not use
• regenera�ve braking, decelera�ng to minimum speed, or coas�ng to a stop for emergency stopping.
• They may not stop a drive that is malfunc�oning. Removing AC line power is the only acceptable
• method for emergency stopping.
• Line star�ng and stopping (applying and removing AC line voltage) is recommended for infrequent
• star�ng and stopping of a drive only. Regenera�ve braking, decelera�ng to minimum speed, or
• coas�ng to a stop is recommended for frequent starts and stops. Frequent star�ng and stopping can
• produce high torque. This may cause damage to motors.
• Do not disconnect any of the motor leads from the drive unless power is removed or the drive is
• disabled. Opening any one lead while the drive is running may destroy the drive.
• The field output is for shunt wound motors only. Do not make any connec�ons to F1 and F2 when
• using a permanent magnet motor.
• Change voltage switch se�ngs only when the drive is disconnected from AC line voltage. Make sure
• both switches are set to their correct posi�on. If the switches are improperly set to a lower voltage
• posi�on, the motor will not run at full voltage and may cause damage to the transformer. If the
• switches are improperly set to a higher voltage, the motor will overspeed, which may cause motor
• damage, or result in bodily injury or loss of life.
• Under no circumstances should power and logic level wires be bundled together.
Maximum
• Be sure poten�ometer tabs do not make contact with the poten�ometer's body. Grounding the
Ra�ng of
• input will cause damage to the drive.
Overcurrent
• This product does not have internal solid state motor overload protec�on. It does not contain speed-
Protec�on

Time
• signals from remote devices for over temperature protec�on. If motor protec�on is needed in the
30 A
Circuit
• end-use product, it needs to be provided by addi�onal equipment in accordance with NEC standards.
Breaker
Line Input
Connect the AC line power leads to terminals L1 and L2, or to a double-pole, single-throw master
power switch (recommended). The switch should be rated at a minimum of 250 VAC and 200% of
motor current.
Motor
Connect the DC armature leads to terminals A1 and A2. If the motor does not spin in the desired
direc�on, power down the drive and reverse these connec�ons.
Field
At 115 VAC, connect the field leads to terminals F1 and L1 for a 50 VDC field or to F1 and F2 for a 100
VDC field. At 230 VAC, connect the field leads to terminals F1 and L1 for a 100 VDC field or to F1 and
F2 for a 200 VDC field. Do not make any connec�ons to F1 and F2 if using a permanent magnet motor.

Connections
Speed Poten�ometer
Use a 10K ohm, 1/4 W poten�ometer for speed control. Connect the counter-clockwise end of the
poten�ometer to S0, wiper to S2, and the clockwise end to S1. If the poten�ometer works
inversely of desired func�onality, (i.e. to increase motor speed, you must turn the poten�ometer
counterclockwire), power off the drive and swap the S0 and S1 connec�ons. See the Opera�on sec�on
for alterna�ve wiring setups.
Inhibit
Short the INHIBIT terminals to regenera�vely brake the motor to zero speed. The INHIBIT terminals
bypass the FWD ACC and REV ACC trim pots. Open the INHIBIT terminals to accelerate the motor to set
speed. ACE offers two accessory plug harnesses for connec�ng to the inhibit terminals; part number
201-0024 [18 in (46 cm) leads] and part number 201-0079 [36 in (91 cm) leads]. Do not use the
inhibit for emergency stopping.
Regenera�ve Brake
Short terminals RB1 and RB2 to regenera�vely brake the motor to zero speed. The regenera�ve brake
circuitry follows the FWD ACC and REV ACC trim pots. Open terminals RB1 and RB2 to accelerate the
motor to set speed. Do not use the regenera�ve braking for emergency stopping.
Enable (Inhibit-Run)
Short pins 1 and 2 on terminal SO502 to coast the motor to zero speed. Short pins 2 and 3 on terminal
SO502 to accelerate the motor to set speed. If no Enable switch is desired, jumper pins 2 and 3 on
SO502 (factory default). ACE offers an accessory plug harness for connec�ng to the enable terminals;
part number 201-0197 [18 in (46 cm) leads]. Do not use the enable for emergency stopping.
Tachogenerator
Using tachogenerator feedback improves speed regula�on from approximately 1% of motor base
speed to 0.1% of motor base speed. Use tachogenerators rated from 7 VDC per 1000 RPM to 50 VDC
per 1000 RPM. Connect the tachogenerator to terminals T1 (posi�ve) and T2 (nega�ve).
+15 and -15
RGA series drive can supply a regulated +15 and -15 VDC voltage (each sourcing 15 mA maximum) with
respect to RB1 or T1 to isolated, external devices.
