Operate the switches and push buttons with an insulated stick (such as a closed
ball-point pen) to avoid touching of live parts.
Make sure to re-attach the inspection cover into the electronic component box
cover and to close the front plate's inspection cover after the job is finished. During
operation of the unit the front plate of the unit should be attached. Settings are
still possible to be made through the inspection opening.
NOTICE
Make sure that all outside panels, except for the service cover on the electrical
component box, are closed while working.
Close the lid of the electrical component box firmly before turning on the power.
