Use the switch, with wall mount plates attached,
as a guide to mark the correct locations of the 4 screws.
The heads of the screws should be less than 6.0 mm in
diameter, and the shafts should be less than 3.5 mm in
diameter, as shown in the figure at the right.
Do not screw the screws in all the way
—
leave about 2 mm to allow room
for sliding the wall mount panel between the wall and the screws.
STEP 3:
Once the screws are fixed in the
wall, insert the four screw heads
through the large parts of the
keyhole-shaped apertures, and
then slide the switch downwards, as
indicated. Tighten the four
screws for added stability.
Grounding the ETM-IES-08-U1-A switch
Grounding and wire routing help limit the effects of noise due to
electromagnetic interference (EMI). Run the ground connection from the
ground screw to the grounding surface prior to connecting devices.
Wiring the Redundant Power Inputs
The top two contacts and the bottom two contacts of the 6-contact terminal
block connector on the switch
’s top panel are used for the
switch
’s
two DC
inputs. Top and front views of one of the terminal block connectors are
shown here.
STEP 1:
Insert the negative/positive DC wires into the
V-/V+ terminals.
STEP 2:
To keep the DC wires from pulling loose, use a
small flat-blade screwdriver to tighten the
wire-clamp screws on the front of the terminal
block connector.
STEP 3:
Insert the plastic terminal block connector prongs
into the terminal block receptor, which is located
on the switch
’s top panel.
Before tightening screws into the wall, make sure the
screw head and shank size are suitable by inserting the
screw into one of the key hole shaped apertures of the
Wall Mounting Plates.
ATTENTION
This product is intended to be mounted to a well-grounded
