PN 45408
Use the following procedure to install the IQ plus
510/710 relay rack option:
1. Ensure power to the indicator is disconnected,
then place the indicator face-down on an
antistatic work mat. Remove the screws that

Caution
protect components from electrostatic
discharge (ESD) when working inside
the indicator enclosure.
2. Assemble relays onto the relay board
(4-channel) or boards (8-channel).

indicator backplate. Mount U-brackets on the
standoffs, place protective shield on top of
brackets, and secure with kep nuts (see
