DANGER
Explosion hazard due to incorrect installation of the device!
Non-compliance results in severe or fatal injuries.
• Carry out installation strictly according to the instructions and national
safety and accident prevention regulations to maintain the explosion
protection.
• Select and install the electrical device so that explosion protection is not

7.3 Installation
7.3.1 Preparation for electrical installation
Remove the cover
• Remove cheese-head screws.
• Carefully lift MCP front cover.
DANGER
Explosion hazard due to open holes, unused cable entries and cable glands!
Non-compliance can result in severe or fatal injuries.
• Only use approved and flameproof (Ex d) cable glands.
• When selecting cable entries, observe the thread type and thread size
in the component documentation.
• Seal thread with non-hardening thread sealant.
• Always close unused holes, cable entries and cable glands using
approved stopping plugs or plugs. Observe IEC/EN 60079-14 for this.
CAUTION
Danger of electric shock due to energised parts!
Non-compliance can result in minor injuries!
• All connections must be disconnected from the power supply.
• Secure the connections against unauthorized switching.
• Correct reassembly of the unit is required to ensure ingress protection
to IP 66.
