Installation, Operation and Maintenance
Make sure you follow all the recommendations in the Harmony HMISTU and
HMISCU user manual, and additionally those listed below.
DANGER
POTENTIAL FOR EXPLOSION
• Confirm that the location is free from explosively hazardous gases or dust
before connecting or disconnecting equipment, replacing or wiring
modules.
• The service temperature in the suitable enclosure must not exceed 50°C
(122 °F).
• Confirm each interface (COM, Ethernet, USB, power line, …) has been
securely locked.
• Confirm that any USB cable has been attached with its appropriate
clamp.
• Install the certified equipment in a protective enclosure providing at least
IP54 protection when applied in zone 2 environments and IP6x when
applied in zone 22 environments. This protective enclosure must be
certified for hazardous areas zone 2 or 22.
• Do not open the protective enclosure while the system is powered up.
• Confirm that the power supply has been turned OFF before
disconnecting, replacing or wiring modules.
• Ensure that ground at power supply is properly connected.
• Do not use equipment that has been damaged.
• Use Touch Pen XBTZGPEN to all terminals at using zone 2 and zone 22
areas to avoid the risk of electrostatic discharges.
• Do not expose the terminal to direct sunlight.
• The terminal must be protected against accidental shocks.
• Do not allow layers of dust to form on terminals: it should be cleaned
regularly.
Failure to follow these instructions will result in death or serious injury.
