1) Output contacts of CRM-93H do not allow switching of di erent phases or 3-phase
voltages (voltage > 250 V).
2) When mounting into steal-plated switchboards, it is necessary to keep a safety distance
of min. 3 mm from terminal’s screws 35-36-38 and 25-26-28 towards the shutter of a
switchboard.

Technical parameters
The device is constructed for 1-phase main installation of 230V AC or AC/DC 12-240 V,
CRM-9S is constructed for connection for 1-phase main AC 12-240 and must be installed in
accordance with regulations and standards applicable in the country of use. Installation,
connection, setting and servicing should be installed by quali ed electrician sta only,
who has learnt these instruction and functions of the device. This device contains
protection against overvoltage peaks and disturbancies in supply. For correct function
of the protection of this device there must be suitable protections of higher degree
(A,B,C) installed in front of them. According to standards elimination of disturbancies
must be ensured. Before installation the main switch must be in position “OFF” and
the device should be de-energized. Don´t install the device to sources of excessive
electro-magnetic interference. By correct installation ensure ideal air circulation so in
case of permanent operation and higher ambient temperature the maximal operating
temperature of the device is not exceeded. For installation and setting use screw-driver
cca 2 mm. The device is fully-electronic - installation should be carried out according to
this fact. Non-problematic function depends also on the way of transportation, storing
and handling. In case of any signs of destruction, deformation, non-function or missing
part, don´t install and claim at your seller it is possible to dismount the device after its
lifetime, recycle, or store in protective dump.
Example of time setting to 8 hours period:
For rough setting use time scale 1-10s on the potentiomenter.
For ne time setting aim for 8s on potentiometer, then recheck accuracy (using
stopwatch etc).
On rough time setting, set potentiometer to originally desired scale 1-10 hours, leave a
ne setting as it is.
More accurate setting of timing for long periods of time
