Caution:
Precaution must be taken during the connection of this equipment to the AC outlet to make sure
the grounding (earthing) is in place and the ground wire is not disconnected.
Caution:
Avoid covering the fan during operation to prevent premature thermal shutdown of the amplifier.
Caution:
Do not position the equipment so that it is difficult to operate the on/off switch.
Caution:
The AMPAQ-PWM devices are made to be used with Quanser designed experiment kits that have
particular actuators. Use caution if the AMPAQ-PWM is being used with your own actuator. Any
load to be used with the AMPAQ-PWM should have a minimum inductance of 0.1 mH.
Caution:
Do not use the cables provided with the AMPAQ-PWM to wire it to experiments that use a different
amplifier module. The AMPAQ-PWM can be used with such experiments only if plant specific
cables are available.

FUSE INSTALLATION
The AMPAQ-PWM has two 3.5 Amp fuses that protect the amplifier from overcurrent through the main power con-
nector. If you find your unit does not output power from the
To Load
connector, or otherwise stops functioning, check
the fuses.
Caution: Make sure the power to the amplifier is disconnected before changing any fuses!
Follow this procedure to install or replace the fuses in the AMPAQ-PWM:
