2.2 Mechanical Installation
This section outlines specifications, procedures, and the environment for proper mechanical installation of the bypass.
u
Installation Environment
Install the Z1000 Bypass in an environment matching the conditions below to prolong its optimum performance life.
Move the disconnect handle into the OFF position to open the enclosure door for all bypass units. The wall mount units have
two full-turn fasteners, CCW to open, that require a flat blade screwdriver to open the enclosure door.
Wall mount units require a minimum 6 inch clearance above and below to achieve adequate heatsink cooling.
No side clearance is required for cooling because the cooling air flow is in and out of the enclosure door at the front surface
of the bypass. To maintain adequate cooling, do not block the enclosure cooling louvers.

Orientation
Install the bypass vertically to maintain maximum cooling effects.
NOTICE: Avoid placing peripheral devices, transformers, or other electronics near the Z1000 Bypass as the noise created can lead to
erroneous operation. If such devices must be used in close proximity to the Bypass, take proper steps to shield the bypass from noise.
NOTICE: Prevent foreign matter such as metal shavings and wire clippings from falling into the Z1000 Bypass during installation. Failure
to comply could result in damage to the bypass. Place a temporary cover over the top of the drive during installation. Remove the temporary
cover before bypass start-up, as the cover will reduce ventilation and cause the Bypass to overheat.
