The CPU Module Type 9442/35-10-00 and Power Module 9445/35-12
with the Socket 9496/35-03-00 are nonincendive apparatus for
installation in Class I, Division 2, Group A-D or Class I, Zone 2, Group
IIC/IIB hazardous location; Providing intrinsically safe BusRail and
Backplane interfaces according to NEC Article 504/505 or Canadian
Electrical Code, CSA C22. Power Supply input, RS485, Ethernet
interfaces as well as the USB interface are nonincendive for Division 2
or Ex nA for Zone 2.
It is not allowed to plug or unplug the Socket from the BusRail while in
operation.
It is not allowed to plug or unplug the CPU from the socket while in
operation.
It is not allowed to plug or unplug the RS485, Ethernet interfaces as
well as the USB interface from or to the CPU while in operation.
The power supply connector of the Power Module may be unplugged
and the Power Module may be removed from the socket while
explosive atmosphere is present and power supply is switched off.
Follow the procedure to plug the Power Module onto the Socket:
o
Plug the Power Module onto the Socket
o
Tighten the Power Modules screw to the Socket (Tightening
torque 1.7 ± 0.2 Nm)
o
Plug the unpowered power supply connector into the Power
Module
o
Secure the power supply connector by tighten both screws to the
Power Module
o
Switch on the power supply
Follow the procedure to unplug the Power Module from the Socket:
o
Switch off all poles of the power supply connector
o
Unscrew both power supply connector screws
o
Unlock and unplug the power supply connector
o
Unscrew the Power Modules screw to the socket
o
Unplug the Power Module from the Socket
Socket 9496/35-03-00
Module supply over BusRail (BusRail Connector):
CL I, DIV 1, A-D / CL I Zone 1, GP IIC/IIB:
Power Supply:
With intrinsically safe type of protection:
Maximum value:
V
OC
= 26.2 V
The circuit requires external current limitation which is provided by the
system
BusRail Address and data bus:
System internal intrinsically safe circuit for up to 16 I/O Modules via BusRail.
Module supply over Backplane (Slot Connectors):
CL I, DIV 1, A-D / CL I Zone 1, GP IIC/IIB:
Power Supply:
With intrinsically safe type of protection:
Maximum value:
V
OC
= 26.2 V
The circuit requires external current limitation which is provided by the
system
Backplane Address and data bus:
System internal intrinsically safe circuit for up to 32 I/O Modules via
Backplane.
Notes:
1.
Electrical Apparatus connected to the Power Module 9445 should not use or generate voltages > 60 V DC (U
m
).
2.
Electrical Apparatus connected to the CPU Module 9442 should not use or generate voltages > 30 V DC (U
m
).
3.
Follow requirements of IEC 60079-14 for devices with U
m
< 250 VAC.
4.
Exceeding the sum of 2 Power Modules 9445 in one system is not allowed.
5.
Exceeding the sum of 2 CPU Modules 9442 in one system is not allowed.
6.
The Socket is installed on a DIN rail and can be screwed onto a metal mounting plate for increased ambient loads (vibrations, temperatures
up to +75 °C). The mounting plate must be made of at least 3 mm of galvanised sheet steel or a metal with better heat dissipation (e.g.
aluminium).
7.
A distance of at least 50 mm must be maintained for intrinsically safe and non-intrinsicallysafe electrical circuits. If a Power Module is placed
in between the CPU Module and the I/O Modules on the BusRail, the requirements is fulfilled.
8.
General Notes see Certification drawing for IS1 resp. IS1+ Remote I/O System No. 9400 6 031 006 1.
WARNING:
Do not disconnect equipment when a flammable or combustable atmosphere is present.
AVERTISSEMENT:
Ne pas débrancher l’équipement en présence d’atmosphère inflammable ou combustible.
