MOUNTING INSTRUCTIONS
This operator interface is primarily designed for
through-panel mounting. Four VESA mount tapped screw-
holes (M4 x 0.7, 5 mm deep) are present on the rear of the
panels to allow for stand or wall mounting. Care should be
taken to remove any loose material from the mounting cut-
out to prevent that material from falling into the operator
interface during installation. A gasket is provided to enable
sealing to NEMA 4X/IP66 specification. Install the nine
mounting clips provided and tighten to 6.0 pound-force inch
(96 ounce-force inch) evenly for uniform gasket compression.
CONNECTING TO EARTH GROUND
Each operator panel has a chassis ground terminal on the back of the unit.
Your unit should be connected to earth ground (protective earth).
The chassis ground is not connected to signal common of the unit.
Maintaining isolation between earth ground and signal common is not required
to operate your unit. But, other equipment connected to this unit may require
isolation between signal common and earth ground. To maintain isolation
between signal common and earth ground care must be taken when connections
are made to the unit. For example, a power supply with isolation between its
signal common and earth ground must be used. Also, plugging in a USB cable
may connect signal common and earth ground. 1
1 USB’s shield may be connected to earth ground at the host. USB’s shield in
turn may also be connected to signal common.
POWER SUPPLY REQUIREMENTS
The G12 requires a 24 VDC power supply. Your unit may draw considerably
less than the maximum rated power depending upon the features being used. As
additional features are used your unit will draw increasing amounts of power.
Items that could cause increases in current are modules, additional on-board
communications, SD card, and other features programmed through Crimson.
In any case, it is very important that the power supply is mounted correctly if
the unit is to operate reliably. Please take care to observe the following points:
– The power supply must be mounted close to the unit, with usually not more
than 6 feet (1.8 m) of cable between the supply and the operator interface.
Ideally, the shortest length possible should be used.
– The wire used to connect the operator interface’s power supply should be
at least 22-gage wire suitably rated for the temperatures of the environment
to which it is being installed. If a longer cable run is used, a heavier gage
wire should be used. The routing of the cable should be kept away from
large contactors, inverters, and other devices which may generate
significant electrical noise.
– A power supply with an NEC Class 2 or Limited Power Source (LPS) and
SELV rating is to be used. This type of power supply provides isolation to
accessible circuits from hazardous voltage levels generated by a mains
power supply due to single faults. SELV is an acronym for “safety extra-
low voltage.” Safety extra-low voltage circuits shall exhibit voltages safe
to touch both under normal operating conditions and after a single fault,
such as a breakdown of a layer of basic insulation or after the failure of a
single component has occurred.
