Micromod Micro-DCI: 53SL6000 Single Loop Controller - Manual (Page 20)

2.1 Inspection
Inspect the equipment upon arrival for damage that
may have occurred during shipment. If damage is
such that faulty operation is likely to result, do not
install the controller and contact the MM Automat-
ion representative if purchased direct, or contact
the appropriate supplier for repair/replacement pro-
cedures. Inspect the packing material before dis-
carding it to prevent the loss of any additional
product literature that may have been included in
the shipment. Also inspect the controller data tag
to ensure it has the correct power requirements for
the intended application (e.g., 120/240 V ac or 24 V
dc).
2.2 Site Location
The 53SL6000 controller is designed to operate on
a plant floor where the controller faceplate might be
exposed to occassional wash-downs. See Section
1.3 for the stated environmental specifications of
the controller.
2.3 Panel Mounting
Dimensions for single and multi-controller mount-
ing in a single panel cutout are provided in Figure
2-1.
2.3.1 Single Cutout Installation
(NEMA4 Compliant)
1. From the rear of the controller, slide on the
rubber O-ring so that it butts against the dis-
play flange.
2. The applicable option modules can be installed
now, before the controller is mounted in the
panel cutout, or after mounting. If installing the
option modules now, see Figure 2-7 to install
the universal analog input module, Figure 2-9
to install the 2DI/2DO module, and Figure 2-
12 to install the RS-232 or RS-485 module.
This step can be skipped if none of these mod-
ules were ordered with the controller.
3. Slide the controller through the panel cutout
and secure it in place using the two mounting
brackets as shown in Figure 2-1.
2.3.2 Multiple Cutout Installation
Multi-controller mounting collar part numbers are
provided in Table B-1, Parts List.
1. If it is desired to cushion the controller from the
collar, then slide on the rubber O-ring from the
rear of the controller so that it butts against the
display flange. This step is optional and not
required.
2. The applicable option modules can be installed
before each controller is mounted in the panel
cutout, or after mounting. If installing the op-
tion modules now, see Figure 2-7 to install the
universal analog input module, Figure 2-9 to
install the 2DI/2DO module, and Figure 2-12
to install the RS-232 or RS-485 module.
This step can be skipped if none of these mod-
ules were ordered with the controllers.
3. Slide each controller through the mounting col-
lar and panel cutout. Secure each controller in
place using the two mounting brackets as
shown in Figure 2-1.
2.4 Power Connections
Figure 2-2 illustrates the power plug location on the
controller backplane. The power plug is removable
and can be pulled straight out from its backplane
connector. The plug is scalloped on one side to
ensure proper insertion after the power wires are
connected.
WARNING: Instruments that are powered from an
ac line service constitute a potential electric shock
hazard to the user; therefore, only qualified
technicians should install the unit. Make certain
that the ac power lines are disconnected from the
operating branch circuit before attempting
electrical connections.
NOTE: Installations are expected to have access
to a high quality, noise-free point of earth
reference. Connection should be through a low
resistance (less than one ohm) lead wire directly
to the installation’s point of earth reference which
can be an independent grounding rod or ground
grid mesh that penetrates the permanent moisture
level below the frost line in accordance with Article
250 of ANSI/NFPA 70, the National Electrical
Code, or other code(s) acceptable to the authority
having jurisdiction over the installation.
NOTE: In electrically noisy locations, use shielded
signal wiring. Also, the power wiring should not
be routed in close proximity to signal wiring.
NOTE: Each power wire lead should be stripped
to expose 1/4 inch (6.4 mm) conductor.
