3 MOUNTING INSTRUCTIONS
The drive is designed with a NEMA-1 / IP-40 enclosure for indoor use. It is recommended that
the drive be mounted vertically on a flat surface with adequate ventilation. Leave enough room
below the drive to allow for AC line, motor connections, and any other wiring that is required.
Care should be taken to avoid extreme hazardous locations where physical damage can occur.
When mounting the drive in an enclosure, the enclosure should be large enough to allow for
proper heat dissipation so that the ambient temperature does not exceed 45°C (113 °F) at full
rating. A mounting template is included to facilitate mounting of the drive.
See Figure 4, on page
14.
The drive is designed with a removable cover. To open the cover, the two front cover screws
must be removed. After mounting and connections, install and tighten the two front cover
screws to 5 lbs-in (6 kg-cm). Do not overtighten.
4 ELECTRICAL CONNECTIONS
See Table 9, on page 14 for terminal block wire and tightening torque specifications.
WARNING! READ ALL SAFETY WARNINGS, ON PAGE 8, BEFORE USING THE
DRIVE. DISCONNECT MAIN POWER BEFORE MAKING CONNECTIONS TO THE DRIVE.
TO AVOID ELECTRIC SHOCK, BE SURE TO PROPERLY GROUND THE DRIVE.
Application Note:
To insure proper operation, position and separate the AC line and motor
connections, signal connections, signal following circuitry, or start/stop contacts. Also, do not
combine (or in close proximity) motor wires from multiple drives in the same conduit. Use
shielded cables on all signal wiring over 12" (30 cm). The shield should be earth grounded on
the drive side only. Connect the drive in accordance with the National Electrical Code
requirements and other local codes that may apply.
Be sure to properly fuse each AC line conductor that is not at ground potential. Do not fuse
neutral or grounded conductors. A separate AC line switch or contactor must be connected as
a disconnect, so that each ungrounded conductor is opened. For fuse or circuit breaker rating,
see Table 7, on page 6. Also see Section 4.1.
