Drive mounting (Chassis drives)
• Mount the drive with its board in either a horizontal or vertical
plane. Eight 0.188 inch (4.8 mm) wide slots in the chassis
accept #8 pan head screws. Fasten either the large base or the
narrow flange of the chassis to the subplate.
• The drive must be earth grounded for noise suppression.
Connect earth ground to the earth ground terminal on the drive’s
bottom board (see Connections).
Drive mounting (Cased drives)
Cased drives come with 0.88 inch (22 mm) conduit holes at the
bottom of the case. The units may be vertically wall mounted or
horizontally bench mounted using the three keyholes on the back
of the case. See Figure 4 (page 5) for mounting hole locations.
1. For access to the keyholes and the terminal strip, remove the
two screws from the front of the case by turning them
counterclockwise. Grasp the front cover and lift it straight out.
2. Install the mounting screws in the three keyholes.
3. Install conduit hardware through the conduit holes at the bottom
of the case. Connect external wiring to the terminal block.
4. Reinstall the front cover. Avoid pinching any wires between the
front cover and the case.
5. Replace the two screws to the front cover. Turn the screws
clockwise to tighten.
6. Set the POWER switch to the OFF position before applying AC
line voltage.
