K. Enable Jumper (J11) –

Jumper J11 is fac-

tory installed to enable the control. If
installing the Enable Circuit, as described
in Section IIJ, on page 13, remove Jumper
J11. See Figure 27.

MOUNTING INSTRUCTIONS

Warning! The KBRC-240D is not designed to be used in an explosion-proof appli-
cation.

It is recommended that the control be mounted vertically on a flat surface with adequate ven-
tilation.  Leave enough room below the control to allow for AC line, motor connections and
any  other  wiring.   Although  the  control  is  designed  for  outdoor  and  wash  down  use,  care
should be taken to avoid extreme hazardous locations where physical damage can occur.  If
the control is mounted in a closed, unventilated location, allow enough room for proper heat
dissipation.  If operating the control at full rating, a minimum enclosure size of 12”W X 24”H
X 12”D is required.  See Figure 3, on page 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 speed control, which has been
installed in the equipment, it is recommended that the following procedure be followed.
Figure 28 shows a typical hi-pot test setup.

Note: All equipment AC line inputs must be disconnected from the AC power.

A.

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 control and other auxiliary equipment are mounted.

B.

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 pro-
cedure must be followed for each machine tested. A suggested hi-pot tester is Slaughter
Model 2550.

WARNING! Instantaneously applying the hi-pot voltage will cause irre-
versible damage to the speed control.
