HDA 5500
6 Installation and commissioning
6.1 Mechanical installation
The HDA 5500 is a control panel unit with a standard mounting housing with the following
measures for mounting:
•
Control panel cut-out of 92 x 45 mm
•
Panel thickness: at least 1.25 mm
•
Mounting depth: at least 150 mm
6.2 Electrical connection
The electrical connection must be carried out by a qualified electrician in accordance with
relevant regulations (in Germany: VDE 0100).
Important:
In order to fulfil the relevant EMC standards, subject to the ambient conditions, the screening
effect of the control box must comply with the EMC standard.
Additional installation notes which, from experience, reduce the effect of electromagnetic
interference:
• Make line connections as short as possible.
• Use screened lines (e. g. LIYCY 4 x 0.5 mm²).
• The cable screening must be fitted by qualified personnel subject to the ambient condi-
tions and with the aim of suppressing interference.
• Direct proximity to interference must be avoided as far as possible.
If inductive loads are to be switched using the relays, varistors must be used on the load to
prevent high switch-off surges.
