Mechanical Installation
The mechanical installation of the SMARTLINK
®
MRV system requires the following:
• SMARTLINK
®
Valve Actuators:
Install the Valve Actuator assemblies in any orientation within the appropriate air and fuel pipe lines. Observe good piping
practice when installing valves. Do not use valves or actuators to support the weight of pipe.

MRV Control Interface and DIN rail-mounted options
(When ordered without Interface Panel)
:
The Control Interface, Relay Input Interface, Relay Output Interface, Network Interface, User Display, and Universal 24VDC
Power Supply can be installed onto a DIN rail in any orientation. When the Control Interface and optional modules are provided
without a MAXON-supplied enclosure, it is the responsibility of the customer to mount these components in an enclosure that
has a rating greater than or equal to IP40 in order to comply with CE safety approvals. To satisfy FM Class I, Division 2, and
ATEX and IEC Ex hazardous area requirements, the enclosure rating must be greater than or equal to NEMA 4.

MRV Control Interface
(When ordered with Interface Panel and no enclosure
):
Refer to panel drawings on following page. All mounting material (bolts, washers, nuts) are included.
The Interface Panel assembly which includes the Control Interface and all rail-mounted options can be mounted in any
orientation. It is the responsibility of the customer to mount this factory-wired panel assembly within an enclosure that has a
rating greater than or equal to IP40 in order to comply with CE safety approvals. To satisfy FM Class I Division 2, and ATEX and
IEC Ex hazardous area requirements, the enclosure rating must be greater than or equal to NEMA 4.

MRV Control Interface
(When ordered with Interface Panel & Enclosure):
The enclosed Control Interface assembly can be mounted in any orientation. All standard MAXON enclosure options are rated
NEMA 4X and IP66. To maintain the environmental rating of the enclosure, NEMA 4X or IP66 conduit fittings (or glands) should
be installed. Provisions for a minimum of two, 1.5 inch should be made for conduit. The preferred hole location for AC power
(or mains) and all AC input/output wiring is on the bottom left or lower left side of the enclosure. The preferred hole location for
all valve actuator communications cable and low voltage (4-20 mA) control/monitoring signals is on the bottom right or lower
right side of the enclosure.
