Solid State Relays (Ssrs) - Vapac VIRTUOSO VE05-1P Installation And Operating Manual

Solid State Relays (SSRs)

A faulty SSR should be replaced with an SSR of the
same (or higher) voltage and amperage rating.
To replace an SSR:-
1. Ensure the I/O/II on the fascia of the unit is in the
'0' (Off) position.
1. Disconnect the unit from the electrical supply.
2. Disconnect the SSR and undo the mounting
screws. The SSR is bedded in thermal compound
to assist heat transfer – it is important that this
is cleaned off and a layer of fresh compound
placed under the replacement SSR, when it is
secured in position.
3. Reconnect the SSR, reconnect the electrical
supply and check the SSR function (as above)
before replacing the access panels.
Use proprietary thread locking compound on the line
voltage terminals of the SSR's.
