ATTENTION: To avoid an electric shock hazard and prevent
thermal damage, ensure that all power to the drive power module
and heat exchanger has been removed before performing any
steps of these instructions. Since control wires from the drive are
connected to the heat exchanger control board, it is necessary to
remove power from the drive as well as the heat exchanger.
!
ATTENTION: To avoid an electric shock hazard, verify that the
voltage on the drive power module bus capacitors has completely
discharged before performing any work on the heat exchanger.
After removing power to the drive power module, wait 5 minutes
for the bus capacitors to discharge. Remove the front cover of the
drive power module (complete cover for Frame 2 drives or lower
front cover for Frame 3A and 3B drives). Measure the DC bus
voltage at the DC+ TESTPOINT and DC- TESTPOINT sockets
on the front of the drive power module. The voltage must be zero.
!
ATTENTION: This heat exchanger control board contains ESD
(Electrostatic Discharge) sensitive parts and assemblies. Static
control precautions are required when installing, testing,
servicing or repairing this assembly. Component damage may
result if ESD control procedures are not followed. If you are not
familiar with static control procedures, refer to Allen-Bradley
publication 8000-4.5.2, “Guarding Against Electrostatic
Damage” or any other applicable ESD protection handbook.
