2.2 Dimensions
2.3 Mounting procedures
(1) Make a rectangular holes corresponding to the number of
instruments to be mounted through the panel by referring to
the panel cutout dimensions.
(2) Insert the instrument into the panel from the panel cutout.
(3) Insert the mounting bracket into the mounting groove of the
instrument.(Fig.1)
(4) Push the mounting bracket into the instrument until the
instrument is firmly fixed to the panel.(Fig.2)
*After inserting the CB900 in the panel, fix it to
the panel rear surface with the two mounting
brackets so that the upper and lower mounting
brackets are positioned diagonally.
!"
The front of the instrument of the waterproof and dustproof construction type (CB900: mounting bracket 4 pieces) conforms to
IP65
with the instrument mounted on the control panel. In order to assure the waterproof and dustproof properties, check that
there is no dislocation of the packing nor clearance between the instrument and mounting frame with the instrument mounted.
!"
If the packing is damaged, contact your nearest RKC agent or our sales office.
!"
The instrument can also be mounted by tightening screws. Insert a hexagon nut in the mounting bracket according to the above
procedure (Fig. 3) to mount the bracket, then fix the instrument with the screw. Use the hexagon nuts and screws attached.
!"
CB900 is used in the above figures for explanation, but the same mounting procedures also apply to CB400/CB500/CB700.

•
Install the noise filter on the panel which is always grounded
and minimize the wiring distance between the noise filter
output side and the instrument power terminals.
NOTES
(1) For thermocouple input, use the specified compensation wire.
(2) For RTD input, use leads with low resistance and having no
resistance differences among the 3 leads.
(3) Conduct input signal wiring away from instrument power,
electric equipment power and load lines to avoid noise
induction.
(4) Conduct instrument power wiring so as not to be influenced by
noise from the electric equipment power. If the instrument may
be affected by external noise, a noise filter should be used.
•
Shorten the distance between twisted power supply wire
pitches. The shorter the distance between the pitches, the
more effective for noise reduction.
•
Do not install fuses and/or switches on the filter output signal
since this may lessen filter effect.

When mounting the instrument by tightening
screw
Insert the L-shaped hook
of the mounting bracket
into the groove, then firmly
secure it in the groove.

When tightening each
screw, tighten it only one
turn just after it touches
the panel.
