INSTALLATION INSTRUCTIONS
It is recommended that the unit be kept at room
temperature for at least 24 hours before applying
power; this is to allow the evaporation of any
condensation resulting from low shipping / storage
temperatures.
US requirement, only: This device must be installed
in a UL-listed enclosure offering adequate space to
maintain the segregation of line voltage field wiring
and Class 2 field wiring.
To avoid electrical shock or equipment damage, you
must switch OFF the power supply before attaching /
removing connections to/from any terminals.
