1	Before starting the installation, check that none of the components of the
	frequency converter are live.
2	If the frequency converter is installed outside either a switchgear,
	separate cubicle or electrical room, it must be equipped with a protection
	cover (see e.g. Figure 6-4) as provided by the regulations for IP21
	protection class. For installations in a switchgear, separate cubicle or
	electrical room, the cable protection plate is normally not necessary.

	cables
	! If the motor cables runs in parallel with other cables, note the
	minimum distances between the motor cables and other cables
	given in the table below.
	! The given distances also apply between the motor cables and
	signal cables of other systems.
	! The maximum length of the motor cables is 300 m (level H,
	units with power greater than 1.5 kW) and 100 m (units with power
	from 0.75 to 1.5 kW).
	! The motor cables should cross other cables at an angle of 90
	degrees.
