Mounting the Transformer Box ENV-PSU
ATTENTION: POWER and CONTROL wiring MUST enter
the box through separate holes.
5.2.1. If wiring the Power Supply box through the bottom of
the enclosure instead of the back, remove the plugs
from the bottom of the box (as shown in PHOTO 5A),
and use them to close the holes in the back of the
mounting plate.
5.2.2. Remove the box from the mounting plate so that the plate
with the four (4) carriage bolts (supplied) may be mount-
ed separately.
5.2.3. Use only liquid-tight fittings or liquid-tight conduit fit-
tings in the two (2) holes in the back of the mounting
plate, or the bottom of the power supply unit. When
using liquid-tight fittings, it is important to use the
appropriate cable width for a snug fit. If a snug fit is
not possible, any liquid-tight
may be used instead.
