Wiring Precautions:
• Before wiring, verify the label for correct model num-
ber and options. Switch off the power when checking.
• Care must be taken to ensure that maximum voltage
ratings specified in Section 3 on previous page are
not exceeded.
• It is recommended that power to these instruments
be protected by fuses and circuit breakers rated at
the minimum value possible.
• All units should be installed inside a suitably ground-
ed metal enclosure to prevent live parts being acces-
sible to human hands and metal tools.
• All wiring must conform to appropriate standards of
good practice, national and local codes and
regulations. Wiring must be suitable for the maximum
voltage, current, and temperature ratings expected in
the system.
• Take care not to over-tighten the terminal screws.
• Unused control terminals should not be used as
jumper points as they may be internally connected,
causing damage to the unit.
• Verify that the ratings of the output devices and the
inputs as specified on page 3 are not exceeded.
• Electric power in industrial environments contains a
certain amount of noise in the form of transient volt-
ages and spikes. This electrical noise can enter and
adversely affect the operation of microprocessor-
based controls. For this reason we strongly recom-
mend the use of shielded thermocouple extension
wire which connects from the sensor to the controller.
This wire is a twisted-pair construction with foil wrap
and drain wire. The drain wire is to be attached to
earth ground at the sensor end only. We carry both
type J and type K in our stock.
RISK OF ELECTRIC SHOCK - Dangerous and poten-
tially fatal voltages are present when working on this
equipment. Before installation or beginning any trou-
bleshooting procedures, the electric power to this equip-
ment must be disconnected and locked out as described
by OSHA Standards. Units suspected of being faulty
must be removed and returned to Ogden for inspection
and/or repair. They contain no user serviceable compo-
nents.
To help minimize the possibility of fire or shock hazards,
do not expose this instrument to rain or excessive
moisture. This control is not to be used in hazardous
locations as defined in Articles 500 and 505 of the
National Electric Code.
Do not use this instrument in areas subject to
hazardous conditions such as excessive shock,
vibration, dirt, moisture, corrosive gases or oil. The
ambient temperature of the areas should not exceed
the maximum rating specified in Section 3, on previous
page.
Unpacking:
Upon receipt of the shipment inspect the unit for ship-
ping damage. If any damage due to transit is noticed,
report and file a claim with the carrier. Write down the
model number and serial number for future reference
when corresponding with our service center. The serial
number is located on the housing of the control.
Mounting:
Make panel cutout to dimensions shown below. Insert
the controller into the panel cutout. The maximum
panel thickness is
