RAMM SOLID STATE DC MOTOR SPEED CONTROL
SAFETY WARNING - PLEASE READ CAREFULLY
This product should be installed and serviced by a qualified technician, electrician or 
electrical maintenance personnel familiar with its operations and the hazards involved. 
Proper installation (see instruction information which accompanies product) which in-
cludes wiring, mounting in proper enclosure, fusing or other over current protection and 
grounding, can reduce the chance of electrical shocks, fires or explosion in this product 
or products used with this product, such as electric motors, switches, coils solenoids 
and/or relays. Eye protection must be worn when working with control under power. 
This product is constructed of materials (plastics, metals, carbon, silicon, etc.) which 
may be a potential hazard. Individual material safety data sheets (MSDS) are avail-
able upon request. Proper shielding, grounding and filtering of this product can reduce 
the emission of radio frequency interference (RFI) which may adversely affect sensitive 
electronic equipment. If information is required on this product, contact our factory. It 
is the responsibility of the ultimate user of this product to read and comply with this 
safety warning. (SW effective 1/89) 
 
IMPORTANT
YOU MUST READ THESE INSTRUCTIONS BEFORE OPERATING CONTROL
1. Be sure AC line voltage corresponds to control voltage. 
 
2. Install the correct plug-in horsepower resistor according to armature voltage and 
motor horsepower.
 
3. Recheck connections: AC line L1 and L2; armature to A+ and A– and field (Shunt 
motors only to F+ and F-). (Note: if motor runs in improper direction, interchange 
armature leads.) 
 
4. Install proper AC line fuse and armature fuse as required. 
 
5. Nominal trimpot settings are as follows (expressed in % of full CW rotation): 
 
Table 1: Nominal Trimpot settings 
 
Min (minimum speed): 15% CL (current limit/torque): 65% 
Max (maximum speed): 65% ACCEL (acceleration start): 20% 
IR (IR compensation): 25% DECEL (deceleration stop): 20%
