Page 11: Mounting
5 – MOUNTING 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. Although the drive is designed for outdoor and washdown use, care should be taken to avoid extreme hazardous locations where physical damage can occur. -

Page 13: Ac Line Input Fusing
6 – AC LINE INPUT FUSING The drive does not contain line fuses. Most electrical codes require that each ungrounded conductor contain circuit protection. Do not fuse neutral or ground connections. It is recommended to install a fuse (Littelfuse 312/314, Buss ABC, or equivalent) or a circuit breaker in series with each ungrounded conductor. -

Page 15: Reconditioning The Bus Capacitors
9 – RECONDITIONIONG THE BUS CAPACITORS If this drive has been in storage for over one year it is necessary to recondition the power supply bus capacitors. To recondition the bus capacitors, apply the AC Line, with the drive in the Stop Mode, for a minimum of one hour. Not following this procedure will cause the bus capacitors to fail. -
Page 16: Boost Mode Selection (J6)
10.5 – BOOST MODE SELECTION (J6) Jumper J6 is factory set to the "FIX" position for Fixed Boost. For Adjustable Boost using the FIGURE 18 BOOST Trimpot, set Jumper J6 to the "ADJ" position. See Figure 18 See Section 12.8 on BOOST MODE SELECTION page 18 for the Boost Trimpot. -
Page 17: Trimpot Adjustments
12 – TRIMPOT ADJUSTMENTS The drive contains trimpots which are factory set for most applications. See Figures 4 – 6 on pages 8 – 10 for the FIGURE 24 location of the trimpots and their approximate factory calibrated positions. Some applications may require MINIMIM SPEED readjustment of the trimpots in order to tailor the drive for a specific requirement. -
Page 18: Boost Trimpot (Boost)
CAUTION! Adjusting the current limit above 160% of the motor nameplate rated current can cause overheating of the motor. Consult the motor manufacturer. Do not leave the motor in a locked rotor condition for more than a few seconds since motor damage may occur. In order to ensure that the motor is properly protected with the I t feature, it is required that the CL Trimpot be set for 160% of the motor nameplate rated current, as described below. -
