INSTALLING UND CONNECTING THE VT-MSPA2-2X
The dimensions of valve amplifier VT-MSPA2-2X are given in data sheet RE
30232-01. The installation orientation is vertical. Observe the required mounting
distances:
• The distance to covers and walls must be at least 2 cm.
• At ambient temperatures above 50 °C, provide a minimum distance of 1 cm to
the next assembly.
• By snapping the housing of the VT-MSPA2-2X on a conductive and earthed
mounting rail, the earth connection is established with the rear wall of the
control cabinet. This constitutes HF grounding of the VT-MSPA2-2X.
• Do not use any silicone-containing sealants, adhesives or insulating agents.
• Ensure maintenance-friendly installation, i.e. simple access to the connection
lines. Ensure free access to the connection side.
• Lay cables and lines so that they cannot be damaged and no one can trip over
them.
Install the VT-MSPA2-2X as follows on a DIN mounting rail in the control cabinet:
1.
Disconnect the relevant system part from the power supply.
2.
Snap the back panel of the VT-MSPA2-2X carefully into position on the DIN
mounting rail. Mechanical contact points on the rear panel of the VT-MSPA2-2X
ensure firm seating on the DIN mounting rail and the connection of the housing
to the grounding system of the control cabinet.
