Operation manual
•
External indicators (if applicable) must be installed where they are clearly visible to
workers from all the operating positions.
•
Make sure that the G9SR system is securely mounted and its cables and connectors
are properly connected.
•
Make sure that foreign objects such as water, oil, or dust do not enter the inside of the
G9SR system.
Perform an inspection for all G9SR systems (as described in section 3 Test on page
•
7) when using series connections, perform inspections for every connected G9SR
system.
•
Use the G9SR Safety Relay within an enclosure with IP54 protection or higher
according to IEC/ EN 60529.
•
Use DIN Track (TH35-7.5/TH35-15 according to IEC 60715) to install the G9SR
Safety Relay into the control panel.
•
Mount the G9SR Safety Relay to the DIN Track using PFP-M End Plates (not
included with the G9SR Safety Relay) to prevent it from falling off the DIN Track
because of vibration. Correctly mount all Units to the DIN Track.
•
Install the G9SR Safety Relay in the vertical direction to ensure adequate cooling.
See also § 2.2 Step 2: Mechanical installation on page 4.
•
Space must be provided around the G9SR Safety Relay, at least 25 mm from its side
surfaces and at least 50 mm from its top and bottom surfaces, for ventilation, wiring
and Unit replacement.
•
Be sure to lock all locking mechanisms, such as those on I/O terminal blocks and
connectors, before attempting to use the G9SR Safety Relay.
Turn OFF the power supply before performing any of the following.
•
Connecting or disconnecting Expansion I/O Units, Option Boards, or any other Units
•
Assembling the G9SR Safety Relay
•
Connecting cables or wiring
•
Connecting or removing terminal blocks
● Installation and Wiring
•
Disconnect the G9SR Safety Relay from the power supply before starting wiring.
Devices connected to the G9SR Safety Relay may operate unexpectedly.
•
Properly apply the specified voltage to the G9SR Safety Relay inputs. Applying an
inappropriate DC voltage or any AC voltage may result in a product failure, reduced
safety functions, damage to the product.
•
Be sure to separate the communications cables and I/O cables from high-
voltage/high-current lines.
•
Be cautious not to get your fingers caught when attaching terminal blocks to the
G9SR Safety Relay.
•
Incorrect wiring may lead to loss of safety functions. Wire conductors correctly and
verify the operation of the G9SR Safety Relay before using the system in which the
G9SR Safety Relay is incorporated.
•
Connect no more than the specified number of additional G9SR-BC units and/or
G9SR-EX units to a G9SR-AD unit.
