• Read and understand this manual before installing, operating, or servicing this Drive. All warnings, cautions, and
instructions must be followed. All activity must be performed by qualified personnel. The Drive must be installed according
to this manual and local codes.
• Do not connect or disconnect wiring while the power is on. Do not remove covers or touch circuit boards while the power is
on. Do not remove or insert the digital operator while power is on.
• Before servicing, disconnect all power to the equipment. The internal capacitor remains charged even after the power supply
is turned off. The charge indicator LED will extinguish when the DC bus voltage is below 50Vdc. To prevent electric shock,
wait at least five minutes after all indicators are OFF and measure DC bus voltage level to confirm safe level.
• Do not perform a withstand voltage test on any part of the unit. This equipment uses sensitive devices and may be damaged
by high voltage.
• The Drive is suitable for circuits capable of delivering not more than 100,000 RMS symmetrical Amperes, 240Vac
maximum (200V Class) and 480Vac maximum (400V Class). Install adequate branch circuit short circuit protection per
applicable codes. Failure to do so may result in equipment damage and/or personal injury. Refer to Appendix E for further
details.
• Do not connect unapproved LC or RC interference suppression filters, capacitors, or overvoltage protection devices to the
output of the Drive. These devices may generate peak currents that exceed Drive specifications.
