DIN-rail mounting -XL I/O Expansion Modules

To mount the module on a 35mm DIN-rail, snap it squarely onto the DIN-rail, as shown below.
 Install the module in an upright position.
 To ensure good ventilation, leave at least 50mm between the device and all other objects
above or below it.
 Install at a maximum distance from high-voltage cables and power equipment.

Wiring

 Do not touch live wires.
 This equipment is designed to operate only in SELV/PELV/Class 2/Limited Power
environments.
 All power supplies in the system must include double insulation. Power supply outputs
must be rated as SELV/PELV/Class 2/Limited Power.
 Do not connect either the 'Neutral or 'Line' signal of the 110/220VAC to device's 0V pin.
 All wiring activities should be performed while power is OFF.
 Use over-current protection, such as a fuse or circuit breaker, to avoid excessive currents
into the power supply connection point.
 Unused points should not be connected (unless otherwise specified). Ignoring this
directive may damage the device.
 Double-check all wiring before turning on the power supply.
 To avoid damaging the wire, do not exceed a maximum torque of:
- Controllers offering a terminal block with pitch of 5mm: 0.5 N·m (5 kgf·cm).
- Controllers offering a terminal block with pitch of 3.81mm f 0.2 N·m (2 kgf·cm).
Caution
 Do not use tin, solder, or any substance on stripped wire that might cause the wire
strand to break.
 Install at maximum distance from high-voltage cables and power equipment.
