or turning off. Power modules are compatible with all 800G
pilot light operators.
• Power module with contact block (catalog number
800GDBxXx-EX)
Power module with contact block combination units are used
within hazardous areas where machine functions are activated
by depressing a push button and the corresponding functional
status is visually indicated. These units are compatible with all

Additional Contact Block and Power Module
Information
Front-of-panel operators are inserted into a mounting hole in an “Ex e”
enclosure or control panel. The respective back-of-panel module is
mounted directly underneath the operator by latching onto a DIN
mounting rail (NS 357.5).
The conductor connection is made by wiring the conductors to
terminals at the back of the contact block, power module, or power
module with contact block combination unit.
Compatibility
Contact blocks, power modules, and power module with contact block
combination units are compatible with specific front-of-panel
operators.
Safety Instructions
Improper installation can cause malfunctioning and the loss of
explosion protection.
All back-of-panel modules and operators can only be used within the
specified ambient temperature range (depending on the voltage and
current).
Use in areas other than those areas specified or the modification of the
product by anyone other than the manufacturer is not permitted and
exempts Rockwell Automation from liability for defects and any
further liability.
The applicable statutory rules and other binding directives that relate
to workplace safety, accident prevention, and environmental
protection must be observed.
Before you commission or restart operation, check compliance with all
applicable laws and directives.
All back-of-panel modules can be used only if they are in a clean and
undamaged condition. Do not modify these modules in any way.
Standards Conformed To
Assemble, Install, and Commission
• Only qualified personnel are allowed to assemble, disassemble,
install, and commission the device.
• Protect devices against mechanical damage or electrostatic
discharge.
• Use suitable tools and install cable firmly.
• Use cable that is rated with an appropriate temperature range
suitable for the application.
Assemble and Disassemble
To mount the contact block or power module, follow these steps:
1. Verify that the contact block or power module is intact (no
cracks).
2. Confirm the back-of-panel module is compatible with the
installed operator (see Compatibility).
3. Position the contact block or power module on the mounting
DIN rail.
4. Align the position of the contact block or power module on
the mounting DIN rail at the front-of-panel operator.

Installation
In hazardous areas, the contact block or power module must be used:
• In appropriate enclosures with “Ex e” increased safety type of
protection. The clearance and creepage distances under IEC/
EN 60079-7 Clauses 4.3 and 4.4 must be observed.
• In an enclosure that corresponds to another approved type of
protection that is specified in IEC/EN 60079-0 Clause 1.
Take care when following these steps to connect the cable:
1. Strip 40 mm (1.575 in.) of sheath off the cable.
2. Remove approximately 6 mm (0.236 in.) of insulation from the
conductors.
3. Prepare the ends of the fine-stranded and multi-stranded
conductors. Crimp wire end sleeves with suitable crimp tools.
Connection cross-sections: 0.75…2.5 mm (18…14 AWG).
4. Open terminal cage and insert conductors.
5. Tighten the terminals to a torque range of 0.4…0.7 N·m
(3.5…6.2 lb·in).
Commissioning
Before commissioning, check the following:
• The device has been installed in compliance with the
regulations.
• The device is not damaged.
• The connection has been established properly (verify that the
conductors are secure).
Maintenance
• Only qualified personnel are allowed to do any maintenance
and fault clearance.
• IEC/EN 60079-17 must be observed.
You must keep the contact block and power module devices in good
condition, operate them properly, monitor them, and clean them
regularly.
• Check all contact blocks, power modules, operators, and cables
regularly for cracks and damage. Verify that they are properly
installed.
Repair and Replacement
• Back-of-panel devices are defective if the contact block does
not function properly or the status indicator does not
illuminate on the power module.
• Devices must be replaced with an equivalent catalog number
from the manufacturer.
