3.1.1 Installation considerations
Consider the following before installing the GC:
1. Anchor the GC solidly before performing electrical connections.
Several options for mounting the unit are covered in this section. The GC is heavy
and the potential for damage to equipment or personnel is high.
2. Ensure that the connections to the enclosure meet local standards.
3. Use approved seals: either cable glands or conduit seals.
a. Install conduit seals within three inches of the enclosure.
b. Seal unused openings with approved blanks (plugs).
Threads for these openings are M32 x 1.5.
4. Remove any packing materials before powering up the unit.
5. Do not power up an open unit unless the surrounding area is certified non-
hazardous.
6. Printers and most laptop computers cannot be used in hazardous areas.
3.2 XA mounting arrangements
The 700XA can be installed in one of the following mounting arrangements:
• Wall mount
• Pole mount
• Floor mount
When putting a unit into its final position, be careful to avoid damaging any of the external
components or their attachments. Due to the size, weight, and shape of the GC, at least
two people are required to safely mount the unit. Also, make sure you understand the
installation procedure before handling the unit, and collect the appropriate tools
beforehand.
