2.1.2 Making a NEMA-4 Mounting
Panel
Details
The EOP5-057 series can be mounted into panels with a depth of over 105mm. It
is recommended that the unit be mounted on the front panel of a steel enclosure,
through an appropriate opening. Allow a clearance of at least 25mm around the
sides of the unit for mounting hardware. Allow clearance for cable connections to
the back of the unit. Unit depth may vary according to cable type used. Typically,
plan a depth to accommodate at least 105mm behind the panel.
NEMA-4
Mounting
Put the unit through the panel cut out. Slide the clamps into the 4 holes provided
around the case. Tighten the clamping screws in an even pattern until the unit is
secured in the panel.
Caution!
Do not over-tighten mounting clamps!
Note:
Specifications:
To seal to NEMA-4 specifications, all supplied mounting clamps must be used and
do not flex panel.
2.1.3 Environmental Considerations
The EOP5-057 series is to be used indoors as built in displays. Make sure that
the displays are installed correctly and that operating limits are followed (See
Hardware Specifications).
Do not operate the unit in areas subject to explosion hazards, flammable gases,
vapors or dusts.
The unit should not be installed where fast temperature variation or high humidity
is present. This will cause condensation of water in the device and damage it.
2.2 Power Connections
2.2.1 Power Requirements
Power Supply
Input voltage: 24V DC
±15%
Fusing
Requirement
If the display does not come on within 2 seconds of power-up, turn off
the power immediately. An internal fuse will prevent damage if the
polarity of the DC power is incorrect. Check wiring to ensure proper
connections and try to power up again.
Caution!
High Voltage
An Internal fuse will prevent damage for over voltage condition,
however it isn‟t guaranteed the internal electronic components are not
damaged.
DC sources should provide proper isolation from main AC power.
Caution!
Emergency
Stop
A hard-wired Emergency Stop should be fitted in any system using the
EOP5-057 to comply with the ICS Safety Recommendations.
Caution!
Supply Voltage
Condition
Do not power the EOP5-057 and inductive loads, or input circuitry to
the controller, with the same power supply.
Note: The 24V DC output from some controllers may not have enough
current to power the EOP5-057.
