Helios Candeo Power System
– AP6C75AA Installation Manual
3.5.3. Earthquake anchoring
Earthquake anchoring is that type used in earthquake areas up to Zone 4 per
requirements from Telcordia Technologies (formerly Bellcore).
CAUTION
Preserving the integrity of earthquake installations
The AP6C75AA Helios Candeo power system frame is
earthquake qualified when properly anchored to a 3000 psi
(2.11 kg per sq. mm) concrete floor. The earthquake
qualification is not valid otherwise.
CAUTION
Preserving the integrity of earthquake installations
Zone 4 (Bellcore) earthquake rating of the power system
cannot be guaranteed on floors other than concrete. When
installed on a wooden floor, the installation is not earthquake
qualified.
Secure the frame(s) to a concrete floor using earthquake anchors as described in
the following procedure (refer to Figure 3.5).
Procedure 3.8 – Securing the frames to a concrete floor with earthquake anchors
Step Action
1
If applicable, install the floor isolation pad where the frame is to be installed.
2
Lower the frame to its exact final position over the anchoring holes (and the
isolation pad if applicable).
3
Drop the anchors into the holes drilled per Procedure 3.2.
4
If necessary, use a hammer to insert the anchors until the upper edge of their
upper anchor sleeves is flush with the frame base. See Figure 3.5.
Note:
The penetration hatch marks on the upper anchor sleeve are at least
flush with the concrete floor or below it.
5
Install the anchoring stud in each anchoring hole.
6
Install the anchoring hardware for each anchor; follow the stack-up order
shown in Figure 3.5.
7
Level the frame for proper horizontal and vertical leveling as required as
required using incompressible shims.
