Mount Your 8720MC-RPS
Regenerative Power Supply
This procedure assumes that you have prepared your panel and understand
how to bond your system. For installation instructions regarding other
equipment and accessories, refer to the instructions that came with those
products.
Follow these steps to mount your 8720MC-RPS units to the panel.
1. Lay out the placement for each system component in the enclosure.
See System Design Guidelines
beginning on page 16 for panel layout
recommendations.
For multiple 8720MC-RPS unit installations, see Mounting Guidelines
beginning on page 24
.
2. Drill holes in the panel for mounting your drive system.
Refer to Product Dimensions
beginning on page 111.
3. Loosely attach the mounting hardware to the panel.
We recommend mounting hardware for 8720MC-RPS units as follows:
• 8720MC-RPS065 units: M5 (#10-32) steel bolts.
• 8720MC-RPS190 units: M8 (5/16-24-32) steel bolts.
Observe bonding techniques as described in Bonding Modules
on
page 19
.
4. Tighten all mounting fasteners.
• 8720MC-RPS065 units: 2.0 N•m (17.7 lb•in) maximum torque
• 8720MC-RPS190 units: 5.5 N•m (48.7 lb•in) maximum torque
IMPORTANT To improve the bond between the drive modules and subpanel,
construct your subpanel out of zinc plated (paint-free) steel.
