MCE SmarTRAQ - Drive Enclosure Cable Access; Over Voltage Protection Unit

Cable Access
The SmarTraq drive enclosure is designed with easy field access in mind. There are access
plates on the enclosure that simplify command signal control and motor connections. The
plates have multiple access holes sized to accept 1/2” conduit collars and fittings. Plates are
secured to the drive enclosure using four phillips-head screws.
When making connections, you can remove the plates and easily attach conduit hardware, fit
wire ends to plug-in connectors, plug in the connectors, then re-attach the plates. When remov-
ing a drive, you can unplug connectors, detach the access plates, and remove the drive enclo-
sure.
Caution
If you need to enlarge the conduit holes, REMOVE the plates and perform the operation
OUTSIDE the drive to avoid damaging drive components or getting metal debris inside the
enclosure. Damage caused by tools or metal debris is NOT COVERED by warranty.
The circuit board assembly is also attached to an easy-access plate. If there is a circuit board
related failure, you can easily unplug motor encoder, control, and over voltage protection unit
connections, unplug power connections, remove the grounding screw, remove the four access
plate screws and slide the entire board assembly out of the enclosure for the fastest possible
replacement time. Please refer to “Board Set Replacement” on page 40.
Over Voltage Protection
The over voltage protection unit is an assembly that mounts between the top drive cover and the
drive enclosure. The protection unit protects drive circuitry from transitory over voltages. To
test the protection unit (with the drive top cover removed), press the black test button on the
OVP unit. The red LED should light while the button is pressed, indicating that the unit is cor-
rectly installed. During normal operation, the LED will light or flicker any time over voltage
exists.
