Installation site
All modules of the S7-1500R/H redundant system are unenclosed equipment. You may only
install unenclosed equipment in housings, cabinets or electrical operating rooms indoors. The
housings, cabinets and electrical operating rooms must guarantee protection against electric
shock and spread of fire. The requirements for mechanical strength must also be met. The
housings, cabinets, and electrical operating rooms must not be accessible without a key or
tool. Personnel must be trained or approved for access.
Installation position
The S7-1500R/H redundant system is designed for use in the following mounting positions:
• Horizontal mounting position up to 60 °C
• Vertical mounting position up to 40 °C
Note
If you use the synchronization modules Sync Module 1 GB FO 40 km (6ES7960-1FE00-0AA5)
in the CPUs 1517H-3 PN or 1518HF-4 PN, then the following maximum ambient
temperatures apply:
• Horizontal mounting position up to 55 °C
• Vertical mounting position up to 35 °C
You can find more information in the Mechanical and climatic ambient conditions section.
Rail
You can mount the following components on the rails alongside the S7-1500R/H-CPUs,
system power/load current supplies:
• Terminals
