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.

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.
