Clamp electrical wires securely with a cable clamp after all wiring is
connected to the terminal block. In addition, run wires securely through
the wiring access channel.
When installing the power lines, do not apply tension to the cables.
Secure the suspended cables at regular intervals, but not too tightly.
Make sure that the terminals do not come into contact with the surface
of the electrical box. If the terminals are too close to the surface, it may
lead to failures at the terminal connection.
Do not clean with, or pour water, into the controller as it could cause
electric shock and/or damage the unit. Do not use strong detergent
such as a solvent. Clean with a soft cloth.
Check that the ground wire is securely connected. Do not connect
ground wiring to gas piping, water piping, lighting conductor, or
telephone ground wiring.
