MOD 30ML Multiloop Controller
MECHANICAL INSTALLATION

2.4 MOUNTING
The controller must be installed in an approved enclosure or installed in a means acceptable
to the authority having jurisdiction for electrical installations.
WARNING
Do not install a MOD 30ML controller in a residential, commercial or light
industrial environment in the European Union.
Select a mounting location where:
 There is minimum vibration.
 The ambient temperature is between 32 and 122°F (0 and 50°C) with a relative humidity
of 5-95% RH (noncondensing). The ambient temperature and humidity requirements
apply to the air directly below the controller.
 The installation allows for free air flow above and below the controller
 If it is necessary to mount two or more controllers above each other, and the room
ambient temperature is above 70°F, heat generated by the lower instruments may raise
the ambient of the upper instruments above the 122°F limit. To assure that operating
temperatures are within specified limits, it is recommended that a fan be installed below
the instruments to force air circulation over the instruments in an upward direction. Air
velocity should be at least 100 to 200 feet per minute.
 The panel provides rigid support for a fully loaded 5.5-pound (2.5 kg) controller and any
other panel devices.
 Electrical wiring routing and support are planned.
Mount the controller as follows:
1. Prepare the panel as indicated in Figure 2-2. Be sure to allow enough clearance under
the front panel of each controller to access the communications jack in the bottom of the
front panel (not present with NEMA 4 option).
2. Draw a 1/4" boundary around cutout for reference when caulking. Apply a 1/4“ bead of
silicon caulking (Loctite # 59530 or equivalent) on the panel around the cutout.
* NOTE:
If NEMA 4 is not required, the controller can be installed without the gasket or the
caulking.
3. Slide instrument housing only into panel cutout.
4. Insert brackets into slots in top and bottom of instrument housing.
Be sure the housing gasket is not pinched or twisted between the instrument housing
and the front of the panel.
5. Tighten retaining screws to a torque of 5 inch-pounds (0.6 Nm) or 1-1/2 turns after
contact is made with the back of the panel.
6. Wipe the excess silicon caulking to form a smooth fill and allow it to dry for 24 hours.
7. After the caulking has dried, insert the instrument into the housing and tighten the jack
screw(s) to 7 to 10 inch-pounds (0.8 to 1.1 Nm) or 1-1/2 turns after the front face draws
into the gasket (two screws for NEMA 4 option, one on top otherwise).
