7 MOUNTING INSTRUCTIONS
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. When mounting
the drive in an enclosure, the enclosure
should be large enough to allow for proper
heat dissipation so that the ambient temper-
ature does not exceed 45 °C (113 °F) at full
rating. See Figures 3 and 4, on page 11.
WARNING! Do not use this drive in
an explosion-proof application.
8 RECOMMENDED HIGH VOLTAGE
DIELECTRIC WITHSTAND TESTING
(HI-POT TESTING)
Testing agencies such as UL, CSA, VDE,
etc., usually require that equipment undergo
a hi-pot test. In order to prevent catastrophic
damage to the drive which has been installed
in the equipment, the following procedure
is recommended. A typical hi-pot test setup
is shown in Figure 29, on page 20. All drives
have been factory hi-pot tested in accor-
dance with UL requirements.
WARNING! All equipment AC line
inputs must be disconnected
from the AC power.
8.1 Connect all equipment AC power input
lines together and connect them to the
H.V. lead of the hi-pot tester. Connect
the RETURN lead of the hi-pot tester
to the frame on which the drive and
other auxiliary equipment are mounted.
8.2 The hi-pot tester must have an
automatic ramp-up to the test voltage and an automatic ramp-down to zero voltage.
Note: If the hi-pot tester does not have automatic ramping, then the hi-pot output must be manually
increased to the test voltage and then manually reduced to zero. This procedure must be followed for
each machine to be tested. A suggested hi-pot tester is Slaughter Model 2550.
CAUTION! Instantly applying the hi-pot voltage will cause irreversible damage to the drive, which will
void the warranty.
