To reduce the risk of severe injury or death to persons,
review these installation safety steps before proceeding:
Read all installation instructions for AV Credenza and AV Credenza
accessories before beginning any installation.
When supporting one or more displays using H544 Support Kit for AV
Credenza, always install the legs. Failure to support the weight of one or
more displays to the ground may result in injury.
Always use H570 Dual Display Kit for AV Credenza in combination with the
display supports and legs of H544 Support Kit. Failure to support the weight
of one or more displays to the ground may result in injury.
Anchor the AV Credenza to the wall for all installations.
Use the wood cleat provided for all installations.
Heavy duty SNAPTOGGLE brand wall anchors and 3/8” diameter screws are
provided for your convenience. While these wall anchors and screws are
suitable for many drywall and steel stud installations, a professional should
determine the best anchoring hardware and method for each specific
installation.

CAUTION: Shock Hazard
AV Credenza is an aluminum enclosure and therefore is electrically
conductive. Like all metal enclosures AV Credenza should be grounded
by a professional to reduce the risk of shock due to static electricity or
electrical shorts. AV Credenza features two ground lug locations for this
purpose. Bonding AV Credenza to a grounded PDU via these grounding
lugs is recommended.
