5.2 Side-by-side Installation

The drive can be mounted side by side but requires the clearance specified in
Table 11: Clearance Required for Cooling
Size IP protection rating
H3 IP20
H4 IP20
H5 IP20
H6 IP20
With IP21/NEMA Type1 option kit mounted, a distance of 50 mm (2 in) between the units is required.

5.3 Operating Environment

In environments with airborne liquids, particles, or corrosive gases, ensure that the IP/Type rating of the equipment matches the
installation environment.
For specifications regarding ambient conditions, see
CONDENSATION
Moisture can condense on the electronic components and cause short circuits. Avoid installation in areas subject to frost. Install
an optional space heater when the drive is colder than the ambient air. Operating in standby mode reduces the risk of condensa-
tion as long as the power dissipation keeps the circuitry free of moisture.
