Routing Cables into the MLM-WB+
After the MLM-WB+ is securely mounted to the wall, route all power, audio, video, and
control cables required for the installation.
ATTENTION: Potential Damage to Property. All electrical installation steps
should be performed by a qualified electrician in accordance with national and
local electrical codes.
Installing the Junction Box
Extron recommends using the UL-listed junction box and receptacles included with
the MLM-WB+. In some cases, such as installations in Europe and Asia, you may need
to use a different kind of junction box and receptacles to meet local electrical code
requirements.
WARNING: Risk of Electric Shock. Improperly grounded or ungrounded
receptacles can allow electrical shocks, which can cause injury and damage
equipment. Receptacle installation should only be performed by a qualified
electrician in accordance with national and local electrical codes.
1. Remove a knockout tab from one of the openings in the junction box.
• Remove a rear knockout tab if the power cable will be routed in from behind the
MLM-WB+.
• Remove one of the top or left conduit knockouts if the power cable will be
inserted via a conduit through the top or bottom of the MLM-WB+.
2. If needed, install a 1.125 inch (2.9 cm) or 1.375 inch (3.5 cm) outer diameter conduit
through one of the knockouts at the top or bottom of the MLM-WB+ enclosure. Use
standard fittings to secure it to the junction box inside the MLM-WB+.
NOTE: The installer is responsible for providing the conduit and fittings; Extron
does not provide these items.
3. Install receptacles into the junction box as follows:
a. If necessary, cut off the mounting strap tabs (ears) of the receptacles so that
the fronts of the receptacles fit snugly against the back side of the junction box
cover.
b. Secure each duplex receptacle to the junction box cover.
