Figure 4. Mounting Options.
The RWD62U can be mounted as follows:
Observe all local installation and mounting regulations.
A On a DIN rail (EN 50 022-35 x 7.5) at least 4.75 inches (120 mm) long for
RWD62U.
B Wall-mounted with two screws. (Minimum length of the screws should be
2.75 inches (70 mm) (φ 3.2 mm).
C Front-mounted using standard elements:
• One DIN rail 5.90 inches (150 mm) long for RWD62U
• Two hexagonal placeholders 1.96 inches (50 mm)
• Washers
• Screws
NOTE: (Ensure all terminations are tightened before final mounting to front
panel.)
D Inside the ARG62.21.
WARNING:
There must be a minimum of 0.31 inches (8 mm) distance from
terminations to panel/enclosures to avoid electric shock.
Electrical Installation
Notes
• Standard cables can be used for the controller. However, when mounting in an
environment greatly exposed to EMI, use only shielded cables.
• The RWD62U is designed for 24 Vac operating voltage.
• Use safety insulating transformers with double insulation as per EN 60742; they
must be designed for 100% Duty.
• When using several transformers in one system, the connection terminals G0
must be galvanically connected.
• Supplying voltages above 24 Vac to low voltage connections may damage or
destroy the controller or any other connected devices. Additionally, connections
to voltages exceeding 24 Vac endanger personal safety.
