Epsilon Eb Digital Servo Drive Installation Manual
Note
For Epsilon drives, surrounding air ambient temperature
can be up to 50°C (122° F) with 3% linear derating for every
degree above 40° C (104° F)
The amount of cooling depends on the size of the enclosure, the
thermal transfer of the enclosure to the ambient air and the
amount of power being dissipated inside the enclosure. Consult
your enclosure manufacturer for assistance with determining
cooling requirements.
Wiring Notes
• To avoid problems associated with EMI (electromagnetic
interference), you should route high power lines (AC input power and
motor power) away from low power lines (encoder feedback, serial
communications, etc.).
• If a neutral wire (not the same as Earth Ground), is supplied from the
building distribution panel it should never be bonded with PE wire in
the enclosure.
• You should consider future troubleshooting and repair when
installing all wiring. All wiring should be either color coded and/or
tagged with industrial wire tabs.
• As a general rule, the minimum cable bend radius is ten times the
cable outer diameter.
• All wiring and cables, stationary and moving, must be protected from
abrasion.
• Ground wires should not be shared with other equipment.
• Ensure that metal to metal contact is made between the enclosure
ground lug and the metal enclosure, not simply through the mounting
bolt and threads.
