16 Installation (Electric) and Service Instructions
Take the following into consideration when designing the control box:
1. To ensure suffi cient airfl ow for cooling, provide air vents (holes, slots, etc.) on the upper, lower, left and right sides of the box, as shown
in the fi gure below. (Be sure not to clog the ventilation hole when setting.)
Ensure that the temperature inside the control box does not exceed 40 °C.

2. Keep the power and communications signal lines as far apart as possible (at least 50 mm, if cabled inside the control box) to reduce the
effects of electrical noise.

Caution
 Do not route communications signal lines or input /
output signal lines close to power supply lines, or routing
them through the same conduit. Doing so may result in
malfunction.
 Mount the unit far away from potential noise sources.
 Do not mount the unit where it could get wet, or in areas of
high humidity.
 Do not mount the unit where it could be subject to excessive
vibration or shocks.
 Mount the unit inside a control box.
(1) Remove the two pan-head bolts from the lower sides and
