1.2 CSA Certification
STOP
For valid CSA certification, all devices (IMR 6000/xx and A6000 modules)
must be marked with the respective CSA lable.
If no CSA lable is available on the respective device, this device is not CSA
certified!
The respective CSA lable looks as shown in the following picture.
1.3 CSA − Conditions of acceptability
This device must be supplied with safety low voltage SELV LPS (C22.2 60950 − 1) 24V. The
voltage required for operation must be drawn from a separate power supply.
The IMR system should be placed in a suitable fire enclosure.
The IMR system is evaluated for an ambient of 0
°
C to 45
°
C.
Adequate ventilation space has to be provided so that heat does not build up. The ventilation
space must be at least 1 RU (1
3/4
inch) in all directions. If the ambient temperature of the rack
rises above 45 ° C, cool this instrument with a forced air fan, cooler, or similar.
When mounting several IMR units above each other in one cabinet, install cooling fan racks in
between instead of the ventilation space. The necessary specifications for cooling fan racks
result from the environmental and sitting criterions of the cabinet and thus cannot be defined
generally.
1.4 Advice for Installation
STOP
According to the IEC 61010 directive, permanently installed systems must be
equipped with a power disconnect device (e.g. a switch or circuit
− breaker
according to IEC60947 − 1 and IEC60947 − 3). When using an IMR rack, in
compliance with this directive, such a switch or breaker must be implemented
into the cabinet installation and easily accessible for the user. Furthermore,
each disconnect devices must be labeled in accordance to the associated
system.
1.5 Installation and Mounting
A prepared 3U slot in a 19” rack, or other Intermas − compatible enclosure, is required for
mounting the A6312 monitor. The slot must be fitted with a 48 − pin plug connector (DIN 41612,
design F 48 M). The pin assignment is listed in the following table.
