CAUTION
When running and securing connecting cables on site,
ensure that the maximum permissible temperatures of

Electronic modules can be damaged by
electrostatic discharges. Before commencing
work, touch grounded objects (such as heating
or water pipes) to discharge static loads.

Note: If connecting cables touch hot components they will
be damaged. When routing and securing connecting
cables on site, ensure that the maximum permissible
temperatures for these cables are not exceeded.
Remove the existing cable grommet when using larger
cross-sections [up to 9/16 in. (7 14 mm)]. Secure the
cable with the cable grommet plugged into the lower
casing section (black).
